1 MARINE ORNAMENTAL FISHES

2 Ornamental sponges Red sponge, Amphimedeonneptune's cup sponge Clathria Bowl sponge

3 IMPORTANT FAMILIES  Acanthuridae :12 species  Balistidae : 8  Scaridae : 9  Labridae : 6  Syngnathidae : 6  Chaetodontidae : 15  Haemulidae : 3  Pomacanthidae : 3

4 IMPORTANT FAMILIES contd..  Triacanthidae : 3 species  Monacanthidae : 2  Scorpaenidae : 2  Theraponidae: 2  Diodontidae : 1  Caesionidae: 1  Dasyatidae : 1  Grammastidae : 1 (Pogonoperca punctata)  Malacanthidae : 1  Zanculidae: 1

5 Families contd …  Ostracidae (Tetrasomus, Lactaria)  Tetradontidae Food fishes / not considered as ornamentals  Lutjanidae  Serranidae (Epinephelus group)  Siganidae  Nemipteridae  Mullidae

6 Syngnathidae  Pipe fishes and seahorses  Small in size  Pipe fishes: long and slender with bony exterior  Seahorses: Horse like;brood pouch in male  Pectoral, anal and caudal fins absent  Feed - zooplankton, copepods, isopods and amphipods  Seahorse four species(Lipton, 1996)  Hippocampus kuda, H. fuscus, H. trimaculatus, (H. histrix), H. spinifera  Schedule 1 of Wild Life Protection Act

7 Hippocampus kuda

8 Scorpion fishes  Mostly venomous  Most popular aquariculture sp  About 30cm  Color red, brown or gray  Feed - crabs and small fishes  Nocturnal  Pterois volitans

9 Pterois volitans-red lion fish

10 Pseudochromidae  Small  Lives under boulders  Pseudochromis and Acanthochromis

11 Chaetodontidae  World wide 113 sp  Feed - coral, algae, small benthic invertebrates  Monogamy  Chaetodon, Heniochus  Small buoyant eggs  Hatching 24-48 hrs

12 Chaetodon collare

13 Pomacanthidae  Angel fishes  Stout backward projecting spine on the lower edge of operculum  Centropage- small in size - <8cm-  Feed algae  Form harems of single dominant male and several females  Pomacanthus relatively larger- 40-45cm  Feed-sponge supplemented with algae, tunicates  Monogamous  P. annularis, P. imperator

14 Pomacanthus annularis

15 Pomacanthus semicirculatus

16 Pomacanthus

17 Pomacentridae  Damsel fishes- anemone fishes  The tentacles touch, poison, and kill fish except for the clown fish.  Protects the clown fish from predators.  Chromis - Guards a small plot of turf for feeding  Abudefduf  Amphiprion: 100- 500 eggs deposited on firm substrate  Parental care-guards the egg  Egg predation-wrasses and butterfly fishes

18 Amphiprion clarkii

19 Amphiprion sebae

20 Chromis sp

21 Abudefduf sexfasciatus

22 Clown fish in anemones

23 Labridae  Wrasses  Iniistius [ Xyrichthys], Thalassoma, Coris  Eats eggs of damsel fish  Omnivorous  Feed-crabs, shrimps, Polychaetes, Zooplankton  Harem found in Labroides - single dominant male followed by several females

24 Iniistius pavo

25 Coris formosa

26 Scaridae  Parrot fishes  Fussed jaw teeth  Feed - coral polyps  Scarus gibbus

27 Chlorurus gibbus (Scarus gibbus)

28 Gobiidae  World species exceed 1600  Wide distribution- fw, estuarine, coral reefs  Cryptocentrus obliquus-pink spot shrimp goby  Omnivorous  Easy to maintain  Makes protective burrows  Lays eggs in clusters-guard by parents  Successfully bred

29 Cryptocentrus leptocephalus (C.obliquus)

30 Acanthuridae  Surgeon fish  Acanthurus, Naso, Zebrasoma  Bony, knife like structure in the middle of the tail.  Naso- two spines

31 Acanthurus leucosternon

32 Naso brevirostris

33 Zebrasoma veliferum

34 Balistidae  Triggerfish  Odonus niger - highly abundant  Feeds- sea urchin, starfish,crabs and shrimps  Size>30cm

35 Odonus niger

36 Balistoides viridescens

37 Rare Species  Zanculus cornutus  Bolbometopon muricatum  Pogonoperca punctata  Low population,-  Low fecundity  Coral destruction  High natural mortality  Predation

38 Zanculus cornutus

39 Porcuppine fish

40 Box fishes Ostracion

41 BREEDING METHODS  Egg depositors : Clown fishes  Mouth Brooder: Apogonids  Pouch breeders: Sea horses  Egg scatterers  Problem in Breeding  Breeding Successful - Sea horses, Anemone fishes, Chaetodon, Pseudochromis, Gobiosoma sp

42 FISHERY  Least exploited  Gears Lift net Seine net Scoop net Traps Hand picking – skin divers Stupefying methods / icthyocides - cyanide, clove oil  Crevice dwellers and Caverns- no specific fishing method

43 CHOOSING A RIGHT FISH FOR AQUARIUM  Avoidance of sensitive sp  Stocking compatible sp  Less fish stock-easily feeding – Anemone fishes, Gobids  Communal living (different type feeders)  Stocking cheap varieties  Segregating big predators (Grouper)
