Law and fishing rules at fishing district Kamenica č. 2

Closed season, fishing hours, minimum sizes and daily limit. For guidance only: check them in the fishing regulations of the fishing district

Closed season for all fish

Section 13, paragraph 1 of the Act

1 Oct – 15 Apr

fishing for all fish prohibitedoutside this period

Exception: on waters where huchen occurs, from 1 Nov to 31 Dec fishing for huchen is possible only with a huchen fishing permit (§ 13, para. 4 and § 19 of the Act).

The protection periods by species (below) apply independently of this closed season.

Daily fishing hours

§ 11 of the Decree

Applies only outside the closed season. Outside these hours fishing is prohibited (§ 14(b) of the Act).

April, September6.00 – 20.00 h

May, August5.00 – 21.00 h

Jun, Jul4.00 – 22.00 h

November, December7.00 – 19.00 h

Months missing from the table fall within the closed season. The hours in November and December on trout and grayling waters relate to the exception for fishing huchen (§ 13, para. 4 of the Act); check in the fishing regulations what may be caught at that time. On border waters the hours in the permit or the fishing regulations apply (§ 11, para. 2 of the Decree). The Act regulates night fishing in two wordings that seem to contradict each other at first sight, so always ask about it in the fishing regulations of the district or the fishing guard.

prohibition of groundbaiting and of several baits (pastes, granules, pellets, cheese, worms, insects, roe)

This is a summary. For baits, hooks and groundbait also read the fishing regulations of the district, because the user may tighten the conditions.

How many fish you may keep per day

§ 14 of the Decree
  • 1pcsBlue groupsterlet, Siberian sturgeon, wels catfish
  • 2pcsGreen groupeel, carp, burbot, zander, pike, tench, barbel, lake brown trout, brown trout, grayling (combined)
  • 4pcsYellow grouprainbow trout, brook trout, common nase, vimba bream; added to the green or blue group (at most 4 fish in total)
  • 5kgOther speciesfor example crucian carp, breams, dace and chub (combined); invasive species are not counted

The blue and green groups cannot be combined. The limit applies per day, also when fishing in several districts, and once it is reached, fishing for that day ends. The species groups follow the SRZ interpretation of January 2026, not the text of the section directly. The district user may set a lower limit in the permit, in which case the stricter one applies.

Protection periods by species§ 10 of the Decree

During this period the species must not be caught, even if the water type otherwise allows fishing at that time. It applies independently of the closed season for all fish.

1 Jan – 15 Mar
burbot
1 Jan – 31 May
grayling, spirlin, northern pike
1 Jan – 15 Jun

Some species are protected all year round (for example zingel and streber, lampreys, gudgeons, spined loaches, maraena whitefish, Carpathian barbel, sabre carp) and fishing for them is always prohibited. The full list of species is in the guide The fishing law, rule by rule.

Minimum sizes§ 12 of the Decree

The shortest length from which you may keep a fish. The district user may raise the size, so look for the valid value in the permit and the fishing regulations.

Show as a list

Total length is measured from the front of the head to the end of the longest ray of the tail fin (§ 12, para. 4). No minimum size applies, for example, to sunbleak, Prussian carp, European perch, roach, stone loach and invasive species.

Before and after fishing

  • Carry your fishing license and permit while fishing and show them when checked (§ 12 of the Act). Check that they are valid.
  • Before you start fishing, write down the date and the district number (no. 4-0950-4-1); after fishing, write down the number and weight of your catch (§ 14(d) of the Act). Fishing without a record is an offense.
  • Prohibited fishing methods, night fishing, competitions and other rules are covered in the guide The fishing law, rule by rule.

As of 6 Nov 2026: Act no. 216/2018 Coll. on fisheries (wording effective 1 Jan 2022) and Decree no. 381/2018 Coll. (wording effective 1 Jan 2019); we found no newer wording. The law may change; you can find the current wording on Slov-Lex (Act) and Slov-Lex (Decree).

Bed and bedrock according to maps

What the bed and banks are made of: rock, sediments and their effect on the water

Bed and bedrock

Bottom and bedrock (ŠGÚDŠ)The bedrock under the water according to the hydrogeological map of Slovakia at 1 : 50,000 (ŠGÚDŠ). It tells whether the surroundings are gravelly, sandy, clayey, muddy or rocky.

Well-oxygenated water and rich food; gravel bars also serve as spawning grounds.

  • Bedrock, stony 20%
  • Gravels 40%
  • Clays and loams 40%
Springs and outflows
2within 1 km

Springs and groundwater outflows bring cooler water into the watercourse in summer and warmer in winter; fish stay near them in extreme weather.

The map shows the bedrock geology, not the exact bottom at the spot. The actual bottom material may differ, especially where sediment has been deposited.

68from 100
Water of below-average suitability for trout

The water is in the bottom 9% of 461 trout fishing districts with data.

  • Best fit: stream zone
  • Most missing: water hardness

Reliability medium: we used 5 water data points; the rest are missing and are not part of the assessment.

  • Stream zoneLevel of evidence: Partly supported

    gradient 43 ‰, 515 m a.s.l. → trout zone

    Based on gradient and elevation, the stream lies in an area that corresponds to the trout zone. This is a natural zone for trout.

    What we know about it

    European streams are divided from source to mouth into zones with typical fish: trout, grayling, barbel and lowland; they are determined mainly by gradient and stream size (Huet 1959), and the zones can also be used to assess the condition of streams (Aarts and Nienhuis 2003). We estimate the zone from the gradient of the fishing district's line and its elevation; it is a simplification without stream width. A match between the zone and the fishing district type adds +1 to quality, a clear mismatch −1.

  • Water hardnessLevel of evidence: Hypothesis

    ≈ 2.3 °dH (0.4 mmol/l of calcium and magnesium), ŠGÚDŠ atlas

    Soft water is poor in minerals and nutrients: there is usually less food, the water is more sensitive to acidification, and metals are more toxic in it.

    What we know about it

    Water with calcium and magnesium is more productive and buffers acidity swings better: trout production was higher in calcareous hard waters (Almodóvar et al. 2006), and an index based on dissolved solids and depth predicts fish yield from lakes (Ryder et al. 1974). In Irish streams, however, geology did not change trout density (Lehane et al. 2004), and Downing et al. (1990) showed that production is related rather to primary production. Hence only ±1 point. Hardness comes from the ŠGÚDŠ atlas, not from a measurement in the fishing district; it replaces the separately assessed bedrock of the basin.

    Sources: Almodóvar et al. 2006; Lehane et al. 2004; Ryder et al. 1974

    32
  • Water acidity (pH)Level of evidence: Partly supported

    pH 7.4, ŠGÚDŠ atlas

    The pH is within the range in which fish commonly thrive.

    What we know about it

    Below about pH 6 fish suffer, and trout and grayling are more sensitive than cyprinids (Alabaster and Lloyd 1982); in acidic soft water, aluminium is released from the soil and damages gills (Gensemer and Playle 1999). The pH from the atlas is a model estimate, so the reduction is only −1 or −2, and only where we have no pH measurement (which is assessed by a separate factor).

    Sources: Alabaster and Lloyd 1982; Gensemer and Playle 1999

    100
  • MineralizationLevel of evidence: Hypothesis

    ≈ 91 mg/l, ŠGÚDŠ atlas

    Very few dissolved solids: poor water, fish grow slowly.

    What we know about it

    Dissolved solids (mineralisation) are related to the fertility of the water, which is why Ryder used them to estimate fish production in lakes (Ryder 1965, Ryder et al. 1974). Downing et al. (1990) showed, however, that primary production is a better predictor of production. It does not enter the score, only the suitability index.

    Sources: Ryder 1965; Ryder et al. 1974; Downing et al. 1990

    61
  • Metals in sedimentLevel of evidence: Partly supported

    0 elements among the highest 10 % in Slovakia (ŠGÚDŠ atlas 1999)

    None of the toxic elements in river sediment is among the highest values. In soft water metals are more toxic, so we rate more strictly.

    What we know about it

    The toxicity of metals to fish decreases with water hardness, because calcium competes with the metal for sites on the gills (Pagenkopf 1983). The ŠGÚDŠ atlas gives only the rank among streams, not a concentration comparable with a limit (MacDonald et al. 2000). In hard water we therefore rate metals more leniently, in soft water more strictly.

    Sources: Pagenkopf 1983; Gensemer and Playle 1999; MacDonald et al. 2000

How this water would suit each type

  • Trout68
  • Grayling61
  • Carp31

The same water data evaluated against the requirements of trout, grayling and carp. The fishing district is registered as a trout district; its type is highlighted.

The index 0 to 100 compares the properties of the water with the requirements of the species (60 is the neutral value, 100 the ideal). The verbal rating comes from comparison with other fishing districts of the same type, because most Slovak waters have good values for their species. The index does not affect whether fish really occur in the fishing district (that is decided by stocking and the manager). Hardness, pH and mineralisation from the atlases are historical and model estimates. Only a small part of this feeds into the conditions score and fishing district quality (hardness ±1, atlas acidity −2 to 0, stream zone match ±1 to quality).

  • OvergrowthClean surface
  • IceNo ice

The watercourse is narrower than a satellite pixel (10 m). The values are therefore taken from a strip around the fishing district line and from pixels where water mixes with the bank, so they are only approximate and may also show the bank. The water surface area is not assessed for a watercourse, and estimates over the water appear in the image only where the watercourse is wider than a satellite pixel.

The last usable image is 267 days old (18 Feb 2026) because the fishing district was cloud-covered.

Five pillars from measurements and registers. A pillar without data is not counted in the index, so check the data reliability too.

  • Oxygenno data–

    We have no measurement or register record for this pillar at this district.

  • Water pollutionno data–

    We have no measurement or register record for this pillar at this district.

  • Nutrients and bloomno data–

    We have no measurement or register record for this pillar at this district.

  • Pollution sources nearbyLandslides nearby: 73 landslides and slope deformations within 3 km, ŠGÚDŠ72

    Landslides deliver fine sediment to the stream, which clouds the water after rain and silts up salmonid spawning grounds. The register also lists old, settled landslides, so the reduction is only small.

  • Acidity and hardnessWater hardness: ≈ 2.3 °dH, ŠGÚDŠ atlas64

    Very soft water is poor in minerals and nutrients: there is usually less food and the fish grow more slowly.

Oxygen has a weight of 30%, water pollution 25%, nutrients and bloom 20%, sources nearby 15%, acidity and hardness 10%. Detailed measurements are in the cards below.

    A gravel and stony bottom is typical of trout and grayling waters: a good food base and spawning grounds.

    What we know about it

    Trout production is higher in limestone hard waters (Almodóvar et al. 2006), but in Irish streams geology did not change trout density and the structure of the channel decided (Lehane et al. 2004). The evidence diverges; the weight is small.

Groundwater reaches streams as base flow, so the connection to the stream at the fishing district is only indirect. Natural substances (iron, manganese, sulfates, conductivity) are not counted in the yearbook-based assessment.

The data comes from the SHMÚ yearbooks (groundwater 2017 to 2025).

Groundwater: measured values

Groundwater nearby (SHMÚ)Measured groundwater values from stations within 10 km of the fishing district (nitrates, harmful substances, ammonium, iron, chlorides) and the SHMÚ yearbooks.

A typical value from 8 groundwater stations within 10 km of the fishing district (nearest 4.1 km), measured in 2025. Closer stations carry more weight. This is groundwater near the district, not a measurement in the watercourse itself. The standard is the limit that SHMÚ gives for the indicator (for drinking water); a value equal to the standard counts as an exceedance, as it does at SHMÚ. The label "somewhere above the standard" means that the typical value is below the standard but at least one station exceeds it; which one is shown on the tile. Fish are more sensitive to some substances than people are.

How it affects fish and the water
Ammonium
Ammonium ions are not very toxic in themselves, but depending on pH and temperature part of them turns into ammonia (NH₃), which damages the gills and stresses fish. The higher the pH and temperature, the more ammonia there is (Emerson et al. 1975). The repealed Directive 2006/44/EC gave a guideline of at most 0.04 mg/l of ammonium for salmonid waters and 0.2 mg/l for cyprinid waters.
Nitrites
Nitrites are toxic to fish: they pass through the gills into the blood and turn hemoglobin into methemoglobin, which does not carry oxygen, so fish "suffocate" even in oxygenated water. Salmonids are the most sensitive; chlorides in the water reduce the toxicity (Lewis and Morris 1986). Directive 2006/44/EC gave a guideline of 0.01 mg/l for salmonid waters.
Nitrates
Nitrates do not harm adult fish immediately, but they feed algae and plants and so contribute to over-fertilization and nighttime oxygen crashes. For sensitive aquatic animals (salmonids, amphibians, some invertebrates) Camargo et al. (2005) recommend keeping nitrates below 2 mg of nitrogen per liter, which is about 9 mg/l of nitrates.
Oxygen
Fish, especially salmonids, need a lot of oxygen. Directive 2006/44/EC gave a guideline of 9 mg/l for salmonid waters (in at least half of the measurements) and never less than 7 mg/l. Groundwater from deeper layers often has less of it; in the stream it is re-oxygenated only after it emerges.
Water temperature
Groundwater has an almost constant temperature throughout the year. Inflow from springs can therefore cool a stream in summer and warm it in winter, and such sections often serve as refuges for cold-water fish (Hayashi and Rosenberry 2002).
pH
Fish tolerate a pH of roughly 6 to 9 (Directive 2006/44/EC). Outside this range the gills are damaged and the toxicity of ammonia and metals changes.
Water hardness
Harder water (more calcium and magnesium) is better for fish: calcium protects the gills and reduces the toxicity of metals such as copper and zinc (Pagenkopf 1983), and keeps the pH stable. Soft water is more sensitive to metals and to acidification.
Iron
Iron is dissolved in groundwater at depth. When the water reaches the air, it oxidizes and precipitates as brown flocs that clog gills, cover gravel with eggs and invertebrates, and destroy shelters (Vuori 1995).
Manganese
Manganese is natural in deeper groundwater. For fish it tends to matter less than iron; the standard applies mainly because of the taste and color of drinking water.
Chlorides
Chlorides come from road salt, fertilizers and waste. The US EPA (1988) set 230 mg/l for long-term protection of aquatic life and 860 mg/l for short-term.
Sulphates
Sulfates are common in groundwater; they come from rocks (for example gypsum), fertilizers and mines. Together with chlorides they raise the mineralization of the water; the standard of 250 mg/l is set for drinking water.
Conductivity
Conductivity shows the total amount of dissolved salts. A higher value in groundwater is often natural (limestone, gypsum), but a sharp increase in a stream points to an inflow of salts from roads, mines or waste.
Metals and metalloids
Copper, zinc, nickel, cadmium and mercury are toxic to fish even at low concentrations, more so in soft water than in hard water (Pagenkopf 1983). The groundwater standard is set for drinking water, not for fish.
Pesticides
Pesticides get into groundwater from fields. The standard of 0.1 µg/l per substance (0.5 µg/l in total) is a drinking-water standard and is very strict; fish are usually harmed only by a much higher concentration. The value mainly shows how heavily the surroundings are burdened by agriculture.
Solvents and benzene
Chlorinated solvents (for example tetrachloroethene) and benzene come from industry, treatment plants and petrol stations. They are toxic and break down slowly in groundwater.
PAHs (combustion, petroleum substances)
PAHs are formed by combustion and petroleum spills. The standard for benzo(a)pyrene (0.01 µg/l) is very strict for drinking water because it is a carcinogen.

inferred covered by younger sediments

Fissure groundwater flows out of the bedrock along faults and at springs. It tends to be cooler in summer and warmer in winter than the water in the stream, so according to anglers' experience fish stay near such places in extreme weather (summer and winter islands of a more suitable temperature).

However, fresh fissure water can have little oxygen. This is anglers' experience, not a phenomenon measured at this fishing district.

Faults are from the geological map at 1 : 50,000. Springs come from a hydrogeological map that covers only some regions, so zero does not mean there are no springs there.

The line is the water of the fishing district, the light band is the 3 km zone in which boreholes, mine workings and burdens were searched for. The map shows the nearest objects (at most a few dozen from each register), not all of them. The points correspond to the position in the register; area objects are marked by their centre.

The data come from registers, maps and atlases of the State Geological Institute of Dionýz Štúr and describe the environment around the water. Proximity of a mine working or burden does not mean the water is polluted. The chemistry of water and sediments is a modelled estimate from interpolated maps of the Geochemical Atlas of Slovakia, not current monitoring or a measurement in the stream.

Geomagnetic activity

Geomagnetic activity (Kp)The planetary Kp index (0 to 9) measures the fluctuation of the Earth's magnetic field. From 5 it counts as a geomagnetic storm. The last 48 hours and a forecast for 24 hours are shown.
09

Kp index

0.3from 9

quiet field

Latest measurement (13 Nov 2026 04:00). The dot on the dial is the highest forecast for the next 24 hours.

Highest forecast Kp in the next 24 hours: 1.7 (quiet field).

Kp (0 to 9) measures the fluctuation of the Earth's magnetic field caused by the solar wind. From 5 it counts as a geomagnetic storm. Fish, especially salmonids and eels, sense the magnetic field. That their bites depend on Kp has not been shown, though: these are anglers' observations and hypotheses.

The value is the same for the whole of Slovakia. It enters the activity score only during a strong geomagnetic storm (a hypothesis, −1 to −2 points).

0tremors

no tremors

Within 150 km over the last 30 days (from magnitude 0.0).

According to angling lore, fish (especially catfish and eels) react restlessly to tremors beforehand or stop biting. This is not reliably proven, and with weak tremors it is coincidence. People mostly do not notice deeper tremors from the Carpathians (for example near Komárno and Dobrá Voda) at all.

The GEOFON catalog is global; weak tremors near Slovakia may not all be in it. It is not counted in the activity score.

Data: © ŠGÚDŠ (geological, geophysical and hydrogeological maps), NOAA SWPC (Kp index), GFZ GEOFON (earthquakes). A link between the geomagnetic field, tremors or radon and fish bites has not been reliably proven, so they are not counted in the activity score. The method is described in Methodology.

Most records: Jun.
How to protect yourself

They breed in standing water, so they are worst around reservoirs, oxbow lakes and floodplain forests, especially at sunset.

How to protect yourself: When fishing in the evening and at night wear long sleeves, repellent and a net. Warmth and humidity after rain speed up mosquito development.

Giant hogweedRisk
