1 Saltwater Fish Species Identification
Mr. Robinson

2 Today We Will Describe saltwater fish habitats
Differentiate between saltwater fish species Identify locations for successful fishing

3 Who Loves to Fish

4 What do you need Reliable radio Compass Life jacket Sea chart

5 Go Fish

6 Fish Classification Cartilaginous Bony fishes Sharks, Skates and rays
Skeletons of cartilage rather than bone Bony fishes Skeletons of bone Over 95% of known fish species

7 Fish Classification Ecological Groupings Inshore (littoral)
Offshore bottom (reef) Offshore migratory (pelagic)

8 Inshore (coastal) Habitat
Most marine fishes locate themselves near the edges of continents

9 Inshore Habitats Estuaries Exposed Beaches
Fresh and salt waters meet and mix Harsh environment Fluctuating salinity and temperature Fish expend energy by swimming in search of better conditions Exposed Beaches Turbulent environment Small disoriented invertebrates provide constant food source

10 Inshore Habitats Salt Marshes Mudflats
Salt tolerable plants invade mudflats One of best nutrient producing habitats Will support large fish and invertebrates Mudflats A feature that allows sediment to accumulate Receding tides expose accumulations Worms, clams and other burrowers are abundant

11 Near-shore Soft Bottoms
Inshore Habitats Seagrass Flats Shallow coastal areas often regress into flats Highly productive habitat Large populations of fish can be supported Near-shore Soft Bottoms Soft, silty featureless bottom Fish are of commercial importance

12 Inshore Species Red Drum
Silver to bronze Black spot at upper base of tail Grayish silver fins Found along passes and channels between bars 3-4 lbs.

13 Inshore Species Speckled Trout
Dark grayish-blue back Silvery bottom Dark spots on upper sides, dorsal fin and tail One or two prominent canine teeth on upper jaw Grassy areas, bays and coastal areas 1-2 lbs.

14 Inshore Species Sheepshead
Convict Fish Vertical black and white bars Sharp spines and gill covers Near pilings, jetties, reefs and shell shores 1-3 lbs.

15 Inshore Species Hardhead Catfish
Dark grey back Silvery-white underneath Coast, bays and inlets Toxic slime on fins ½-3 lbs.

16 Inshore Species Southern Flounder
Dark olive to lighter brown Lies on side White underside Both eyes on “up” side Sandy and silty bottoms along shores and estuaries Caught by gigging 1-2 lbs.

17 Inshore Species Atlantic Stingray
Brownish above White underneath Rhomboid shape Triangular nose Painful tail spine Found on or close to bottom 6-8 inches wide and up to 2 feet in length

18 Inshore Species Bull Shark
Dark gray above White below Wide head, blunt snout, and heavy body Live in fresh and salt waters Found in estuaries, bays and shallow waters Up to 500 lbs. and 10 feet long

19 Inshore Species Tarpon
Silver king Body jaws, elongated dorsal fin, falcate anal fin, and large flat scales Exciting catch Found in estuaries, bays and inlets 30-80 lbs.

20 Deep Sea Habitats Natural Reefs Artificial Reefs
Abundance of food and shelter Reduced wave activity “Fish eat fish” world Artificial Reefs Most costly to incorporate Many fish seek out for shelter Sunken objects Burned car shells Bundles of clay and concrete Pipe Oyster shells Sunken ships

21 Fish Eat Fish World Catch small fish Notice increase in strength
Pull up much larger fish

22 Deep Sea Habitats Blue Water Line Off-Shore Oil Rigs
Two currents come in contact Forms line of sediment and trash Allows fish to hide from predators Off-Shore Oil Rigs Supports covered with algae, crustaceans and snails Trolling Avoid close passes for safety Still fishing Tie up to support Attracts fish from depths

23 Deep Sea Habitats Objects Floating debris Turtles Fishing boats
Smaller fish escape nets Throw undesirable species overboard

24 Bottom/Reef Offshore Species Red Snapper
Deep rosy color with dark fringe around fins Often confused with redfish United dorsal fin Found close to the bottom Strike chum bait rather than lures

25 Bottom/Reef Offshore Species Jewfish
Dark to chocolate brown Round tailfins Large reaching lbs. Good spear fishing

26 Migratory Offshore Species Wahoo
Dark blue above, lavender sides and silver underneath Young have distinctive vertical bars Solitary feeder 20 lbs.

27 Migratory Offshore Species Cobia
Dark brown to black above with white below Spike like spines on dorsal fins Dark band from snout to tail Tendency to associate with floating objects 15-30 lbs.

28 Migratory Offshore Species Spanish Mackerel
Black top, blue-green sides and silver below Orange to brown spots Huge schools along coast Found in mouth passes into the gulf Most abundant during summer 1-2 lbs.

29 Migratory Offshore Species Blackfin Tuna
Dark blue back to silver below Vertical bars and dots along sides May have yellow streak on sides Live and move freely in the open sea 10-20 lbs.

30 Migratory Offshore Species Blue Marlin
Deep blue above to silvery-white underneath Vertical lavender bars appear when hooked Found in deep blue waters far offshore Highly sought after sport fish 200 lbs.

31 YOU What Did Learn
