Aquariculture of marine ornamental fish |
At Vizhinjam, 68 species belonging to 17 families of ornamental fish were identified. Of these, Abudefduf spp (Pomacentridae), Chaetodon collaris (Chaetodontidae), Apogon taeniatus (Apogonidae),Thalassoma lunare (Labridae), Siganus javus and S. canaliculatus (Siganidae) Sargocentron rubrum (Holocentridae), Acanthurus nigricauda,Ctenochaetus striatus and A. philippinus (Acanthuridae) Parupeneus indicus and P. macronemus (Mullidae), Scarus ghobban (Scaridae), Platax orbicularis (Platacidae) are very important. |
About 40 species of important aquarium fishes were maintained in aquaria, by feeding them with different feeds; it was found that majority of the marine aquarium fishes could sustain on cooked mussel meat. On the basis of the work in this project, a marine aquarium was established at Vizhinjam for the benefit of the public and the tourists |
At Mandapam in the Gulf of Mannar and Palk bay, the dominant species are Chaetodon collaris, C. octofasciatus, Heniochus acuminatus, Abudefduf septemfasciatus, Siganus oramin, S. javus, Sargocentron rubrum, Syngnathus biaculeatus and Hippocampus kuda. |
Culture of Groupers, Seabass, Rabbitfish and Ornamental fish | |
The important species under culture experiments are the groupers (Serranidae), rabbit fish (Siganidae) and ornamental fish (Pomacentridae). | |
A breakthrough in the brood stock development and breeding of the grouper Epinephelus tauvina was achieved at Cochin Fisheries Harbour Laboratory. The major achievements in the experiments at Cochin are: | |
Successful rearing, from fingerlings, of groupers and development of brood stock in onshore, fully controlled, seawater recirculating system | |
Sex reversal, maturation and spontaneous spawning under onshore captive conditions | |
successful fertilization and larval hatching |
