  1. Family Gadidae • Cods • Commercially important species: • Atlantic Cod (Gadus morhua) • Pollock (Pollachius virens) • Haddock (Melanogrammus aeglefinus) Melanogrammus aeglefinus Gadidae thru Fundulidae

  2. Family Gadidae • Local species • Southern Hake (Urophycis floridana) • Spotted Hake (Urophycis regia) Urophycis floridana Gadidae thru Fundulidae

  3. Gadidae Characteristics • Bottom oriented marine fishes that play an integral ecological role in their communities • Long dorsal and anal fins • Cods have 3 sections of the dorsal fin and 2 sections of the anal fin • Hakes have 2 sections of the dorsal fin and 1 section of the anal fin Gadidae thru Fundulidae

  4. Atlantic Cod • Important because of size and ease of capture • The fishery has collapsed on both the Grand and Georges Bank Gadus morhua Gadidae thru Fundulidae

  5. Family Ophidiidae • Cusk-Eels • Local Species: Blotched Cusk-Eel (Ophidion grayi) Gadidae thru Fundulidae

  6. Ophidiidae Characteristics • Dorsal and anal fins are continuous, with modified pelvic fins as barbels on the jaw • Range in habitats from tide pools to the deepest parts of the world’s oceans Gadidae thru Fundulidae

  7. Pearlfishes • Related family: Pearlfishes (Carapidae) • Closely associated with several marine invertebrates. • Relationships range from commensal - parasitic Gadidae thru Fundulidae

  9. Family Exocoetidae • Flyingfishes • Margined Flyingfish (Cypselurus cyanopterus) • Halfbeaks • Ballyhoo (Hemiramphus brasiliensis) • Halfbeak (Hyporhamphus unifasciatus) Cypselurus cyanopterus Gadidae thru Fundulidae

  10. Single dorsal and anal fins located close to the caudal fin Well-developed lateral line located near the ventral surface Coastal and oceanic, tropical and subtropical waters Exocoetidae Characteristics Gadidae thru Fundulidae

  11. Exocoetidae Larvae Fahay Gadidae thru Fundulidae

  12. Flyingfishes • Long pectoral fin used for gliding after they jump from the water • Lower lobe on caudal fin increases glide distance by sculling in the water Gadidae thru Fundulidae

  13. Halfbeaks • Elongated lower jaw • Used as funnel for directing plankton into the mouth • Popular bait fish for sportsmen Ballyhoo Gadidae thru Fundulidae

  14. Family Belonidae • Needlefishes • Species: • Houndfish (Tylosurus crocodilus) • Atlantic Needlefish (Strongylura marina) Strongylura marina Gadidae thru Fundulidae

  15. Belonidae Characteristics • Prey on small fish with long jaws and well-developed teeth • Fast pelagic spp; have a habit of skipping on the surface • Houndfish is the largest: 5ft. And 10 lbs. Gadidae thru Fundulidae

  16. Family Fundulidae • Killifishes • Common species: • Mummichog (Fundulus heteroclitus) • Striped Killifish (Fundulus majalis) Fundulus heteroclitus (male) Gadidae thru Fundulidae

  17. Fundulidae Characteristics • Found in waters that experience extreme changes in physical parameters • Schooling fish; occur in bays and estuaries • Usually small < 15 cm., omnivores • Most species are sexually dimorphic • Mummichog • Striped Killifish Gadidae thru Fundulidae
