| Notable Contributions of the Division in the
Recent Past |
|
Estimation of the stock parameters of twelve
major species contributing to the demersal finfish yield significantly |
|
Breakthrough in broodstock development from
fingerlings to adult size, sex reversal, maturation, spawning and fertilisation
and larval rearing in an onshore, indoor, fully controlled, seawater recirculating
system developed at Cochin |
|
Aquariculture of marine ornamental fishes occurring
in the Mandapam and Vizhinjam regions and their relative abundance; the
study revealed the presence of 68 species belonging to 17 families of ornamental
fish at Vizhinjam. Nine species dominate at Mandapam in the Gulf of Mannar
and Palk Bay region |
|
Spawning of the clown fish Amphiprion chrysogaster
in FRP tanks at Vizhinjam and successful rearing of the larvae to juveniles
under laboratory conditions |
|
Information on present status of knowledge on
the distribution of groupers and snappers along the northwest coast, off
Kerala, Wadge bank and Gulf of Mannar, in depths up to 360 m, which are
not trawlable owing rocky and coralline growths and suggestions for fishing
these resources through trapping and long lining |
|
Estimation of stock size, maximum possible yield
and catch quotas of 165 species of ornamental fishes of Lakshadweep |
|
Successful conduct of “Summer School on Marine
Fisheries Resources Assessment and Management” in May-June 1999 |
