1. Wildlife and Fishery Science

2. Fish
Cold blooded animals that depend on their environment for body heat
Freshwater and Saltwater environments
Crucial anatomy features
Shapes and sizes of body parts vary with species
Breathing
Gills
How does this work?!

3. Breathing
Water containing dissolved oxygen passes through the GILLS of the fish
Oxygen enters the tissue in the gills where it becomes attached to blood cells
Waste materials flow across the gill tissue to the surrounding water
Breathing

4. Reproduction
Spawn
Reproduce
Females deposit roe (eggs) in depressions beneath the water
Male fertilizers by discharging milt (sperm) on the surfaces

5. Freshwater Fish Freshwater
All the waters on this continent that are not high in salt continent
Most springs, streams, rivers, lakes, marshes, canals, and ponds
These sources vary greatly across the continent
Temperature, Oxygen Content, pH, rate of flow, dissolved nutrients, and degree of pollution

6. Catfish 2 Families, 46 Species in North America
Largest Family, Bullhead
45 species from Canada to Mexico

7. Bullhead Catfish 4 pairs of barbels (feelers or whiskers)
Give the fish a sense of touch to locate food
Bony spines located at the bases of their dorsal fins
Pectoral fins correspond to front legs in terrestrial animals
Adipose fins store fat
Pelvic Fins correspond to rear legs
Prominent Anal fin
Tough Skins and No Scales and Sharp Spines

9. Sunfish Native to North America These fish are laterally compressed
Greater measure from their back to their belly than from side to side
Become active in direct sunlight
This family includes basses, crappies, and bluegills
Several distinctly different fishes belonging to different families are among the basses

10. Sunfish Mating Males build nests in which the females lay their eggs
Nests are a shallow depression in the gravel or sand
Males fan the loose material away with his fins
Each male defends a small area in the vicinity of the nest, the eggs, and the small fish.
Sunfish of different species may mate together producing hybrids
Commonly happens when the water is polluted or dirty
Potentially because they have trouble distinguishing between different species.

14. Trout, Carp, and Whitefish
Several species of this family will migrate to the ocean. These species are strictly freshwater.
Large number of species even though they look quite different, divided into different groups or races within the species
Most migrate to their spawning areas
They spawn in clean gravel so that the eggs can be trapped in the rocks and the eggs are well aerated.
