Fish and Fishing Flashcards
Vertebral Column
a series of approximately 33 bones called vertebrae, which are separated by intervertebral discs. The column can be divided into five different regions, with each region characterised by a different vertebral structure.
Neural crest
a transient embryonic structure in vertebrates that gives rise to most of the peripheral nervous system and to several non-neural cell types, including smooth muscle cells of the cardiovascular system, pigment cells in the skin, and craniofacial bones, cartilage, and connective tissue.
Fin
A fin is a thin component or appendage attached to a larger body or structure.
Scale
each of the small, thin horny or bony plates protecting the skin of fish and reptiles, typically overlapping one another
Operculum
a series of bones found in bony fish that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding
Atrium
each of the two upper cavities of the heart from which blood is passed to the ventricles
Ventricle
each of the two main chambers of the heart, left and right.
each of the four connected fluid-filled cavities in the center of the brain
Nephron
each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine.
Lateral line
a visible line along the side of a fish consisting of a series of sense organs that detect pressure and vibration
Spawning
release or deposit eggs
Swim bladder
a gas-filled sac present in the body of many bony fishes, used to maintain and control buoyancy.
Jawless fish
Jaws are absent.
Paired fins are generally absent.
Early species had heavy bony scales and plates in their skin, but these are not present in living species.
In most cases the skeleton is cartilaginous.
The embryonic notochord persists in the adult.
Seven or more paired gill pouches are present.
Cartilaginous fish
Paired fins. Paired nostrils. Scales. Two-chambered hearts. Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone.
Bony fish
Bony fish are members of the class osteichthyes, and are defined by their calcified skeleton, hinged jaw, gill arches, gill filaments, and gill rakers. They also have an operculum for pumping water across the gills and swim bladders to control buoyancy, as well as mucous-lined scales
Bowfin/Dogfish
has flat head with tube-like nostrils and strong jaws filled with sharp, cone-shaped teeth. Unlike other species of fish, bowfin uses gas-bladder to maintain buoyancy and to facilitate breathing of the fresh air
Brown Bullhead
grows to be approximately 21 inches in length and is darker brown green dorsally growing lighter green and yellow towards the ventral surface
brown trout
lacustris reaches an average length of 40–80 cm (16–31 in) with a maximum length of 140 cm (55 in) and about 60 pounds (27 kg). The spawning behaviour of brown trout is similar to that of the closely related Atlantic salmon.
Eelpouts
Eelpouts are thick-lipped, eel-shaped fishes with the dorsal and anal fins connected around the end of the tail and with small pelvic fins that, if present, are near the gills. They live on the bottom and range from shallow to deep water.
Channel Catfish
A catfish is easily distinguished from other species of fish because of their smooth, scaleless bodies. The channel catfish is olive to light blue in color with black speckles on the sides, has a forked tail, whisker-like organs around the mouth, a broad flat head, and a slender body.
Common Carp
Family. Minnows (Cyprinidae)
Body. Mouth and Snout: Subterminal with 2 obvious barbels on each side. …
Fins. Elongated dorsal fin with 15-23 rays. …
Distinguishing Characteristics. Carp have large scales, a long dorsal fin with a serrated spine, and 15-23 soft rays
Crappie
are most accurately identified by the seven or eight spines on its dorsal fin. Crappies have a deep and laterally compressed body. They are usually silvery-gray to green in color and show irregular or mottled black splotches over the entire body. Both black and white crappies
Flathead Catfish
it looks like any other catfish: it has smooth, scaleless skin, whisker-like barbels around the mouth, and long spines on the dorsal (back) fin and one on each side of the pectoral (shoulder) fin.
Lake Sturgeon
can be huge, topping six feet (two meters) long and weighing nearly 200 pounds (90 kilograms). They are also extremely long-lived.
Lake Trout
Family: Salmonids – Salmonidae.
Similar species: arctic char, brook trout.
Size: In lake Inari usually 40–80 cm, 0.7–2 kg, max. …
Appearance: Somewhat more angular in appearance than other Finnish members of the genus Salvelinus (chars). …
Colouring: Sides usually dark brown, sometimes greenish or dark grey, almost black.
