  13. Fish ID Bluegill • Small, flattened fish, • shaped like the palm of a hand • 2 part dorsal fin – spines in front, and soft rays in back • Small mouth • (edge of mouth doesn’t reach the front of the eye) • Dark vertical stripes on sides • Ear flap is black • Breast is yellow/orange • Chin and lower part of gill cover is blue

  14. Fish ID Bluegill Spines are sharp like needles! They help protect the fish from larger fish. • Small, flattened fish, • shaped like the palm of a hand • 2 part dorsal fin – spines in front, and soft rays in back • Small mouth • (edge of mouth doesn’t reach the front of the eye) • Dark vertical stripes on sides • Ear flap is black • Breast is yellow/orange • Chin and lower part of gill cover is blue

  15. Fish ID Bluegill Bluegill spend most of their time in vegetation. The vertical stripes help camouflage them. • Small, flattened fish, • shaped like the palm of a hand • 2 part dorsal fin – spines in front, and soft rays in back • Small mouth • (edge of mouth doesn’t reach the front of the eye) • Dark vertical stripes on sides • Ear flap is black • Breast is yellow/orange • Chin and lower part of gill cover is blue

  16. Fish ID Bluegill Bluegill primarily eat aquatic insects and other invertebrates. • Small, flattened fish, • shaped like the palm of a hand • 2 part dorsal fin – spines in front, and soft rays in back • Small mouth • (edge of mouth doesn’t reach the front of the eye) • Dark vertical stripes on sides • Ear flap is black • Breast is yellow/orange • Chin and lower part of gill cover is blue

  17. Fish ID Green Sunfish • Distinguished from bluegill by: • Body is longer than round • Larger mouth • (edge of mouth reaches the front of the eye) • Fins tipped in yellow/orange • Ear flap has yellow/orange edge • Blue streaks on the sides of head

  18. Fish ID Largemouth Bass • Body is long instead of round • Very large mouth • (edge of mouth reaches past the eye) • White on bottom • Dark stripe on sides • Spiny and soft-rayed parts of dorsal fin nearly separate • Can get larger than sunfish – up to 10 lbs. in Nebraska

  19. Fish ID Largemouth Bass Dark on top & light on bottom is called countershading. It camouflages a fish from predators. • Body is long instead of round • Very large mouth • (edge of mouth reaches past the eye) • White on bottom • Dark stripe on sides • Spiny and soft-rayed parts of dorsal fin nearly separate • Can get larger than sunfish – up to 10 lbs. in Nebraska

  20. Fish ID Channel Catfish • No scales on body • Whiskers (barbels) on mouth • Small fatty adipose fin on back • When small, dark spots on sides of body • Forked tail fin • Can get very large – record is 41.5 lbs. in Nebraska

  21. Fish ID Channel Catfish Barbels don’t sting! They are covered in ‘tastebuds’ and used to locate food. Spines on the pelvic & dorsal fins are the things to be careful of! • No scales on body • Whiskers (barbels) on mouth • Small fatty adipose fin on back • When small, dark spots on sides of body • Forked tail fin • Can get very large – record is 41.5 lbs. in Nebraska

  22. Fish ID Black Bullhead • Distinguished from channel catfish by: • No spots on sides of body • Brown or golden orange color • Rounded tail fin • Does not grow to large sizes

  23. Fish ID Rainbow Trout • Long, streamlined body • Very small scales • Small fatty adipose fin on back • Small black spots on body and tail fin, dorsal fin • Pinkish stripe on sides • Can get large – record is 14 lbs. in Nebraska
