Title: Saltwater Fish Species Identification


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
  • Knowledge

5
  • Go Fish

6
Fish Classification
  • Cartilaginous
  • 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
  • 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
  • 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
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
  • 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
  • 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 400-500 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.
