Czech First Fishing Licence Knowledge Verification: freshwater angling flashcards

24 cards. Read the term and the definition here. The deck at the top of this page is optional.

Vousky

Barbels containing sensory structures in relevant fish, whose number and position can assist identification without being unique to every member of one family.

Tuková ploutvička

An adipose fin observed in relevant fish groups, useful as one identification feature alongside the complete body, head and other fins.

Postranní čára

A sensory system detecting relevant water movement and pressure changes, distinct from a fish’s eyes, taste receptors and swim bladder.

Zooplankton

Small drifting aquatic animals such as relevant crustaceans that can participate in freshwater food webs rather than being simply juvenile fish.

Plynový měchýř

The swim bladder contributing to buoyancy in many bony fish, with different gas-regulation structures and no universal guarantee against pressure injury.

Osmoregulace

Physiological regulation of internal water and salt balance, important because ordinary freshwater fish body fluids differ in concentration from the surrounding water.

Dissolved oxygen

Oxygen present in water and available for relevant aquatic respiration, measured with stated units and interpreted with temperature, species and conditions.

Respirace

Metabolic use of oxygen in relevant organisms, continuing during darkness even when light-dependent photosynthetic oxygen production has stopped.

Tření

Fish reproduction involving the actual species’ spawning behavior and habitat, distinct from the calendar dates of a legal closed season.

Položená

A bottom-angling method whose actual definition, rigs and allowed use must be checked separately from float, spinning and fly arrangements.

Přívlač

A regulated active lure method with actual rod, hook, seasonal and water-type conditions, not simply any rig marketed with the word lure.

Muškaření

An angling method involving artificial fly imitations under its actual definition, which can change treatment when movement-attracting attachments are added.

Brzda navijáku

A reel drag allowing controlled line release under tension, helping manage loads without removing line, knot, hook or rod limitations.

Vyprošťovač háčků

A suitable hook-removal tool used as part of careful handling, distinct from authority to perform an invasive improvised medical or fish procedure.

Alkalinity

The water’s acid-neutralizing and buffering capacity, distinct from hardness, dissolved oxygen, fish abundance and a direct pH measurement.

Hardness

A property generally reflecting dissolved calcium and magnesium ions, not interchangeable with alkalinity or a complete measure of water quality.

Eutrofizace

Nutrient enrichment that can alter aquatic production and oxygen conditions, with consequences depending on actual inputs, organisms and water dynamics.

Biosecurity

Measures reducing transfer of organisms and contaminated material between sites, including appropriate equipment care and lawful handling rather than uncontrolled stocking.

Rybí přechod

A structure intended to improve fish movement past a barrier, whose effectiveness depends on design, species and flows and does not create unrestricted fishing access.

Rybářský lístek

The Czech state fishing licence, distinct from association membership and the district user’s angling permission for the actual intended place.

Povolenka k lovu

The permission issued by the fishery user for relevant districts and conditions, recognized in its actual lawful paper or electronic form.

Rybářský revír

The actual legally designated fishing district, whose boundaries and applicable conditions matter rather than an approximate map pin alone.

Doba hájení

An applicable closed-season protection, separate from minimum length and daily hours, which a preferred target or long fish does not automatically override.

Evidence docházky

The required factual attendance record identifying the actual date and district or subdistrict, not a prediction of unconfirmed future catches.
