Pearl oysters and pearl production techniques- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Pearl oysters are soft bodied marine pearl producing bivalve mollusk with hard protective shell. These animals produce pearls. About 29 species of pearl oysters are available in the world and distributed in tropical and subtropical regions

Mussel seed resources of India and seeding methods

Commercial farming of mussel is dependent on the availability of seed. The natural spat fall is considered to be the primary source of seed. Although technology for production of mussel seed in hatchery has been perfected but it is not economically viable for commercial farming

Mussel culture

The annual production of mussels, which was 10,000 tonnes in the early 1990's, doubled by 2002 through increased exploitation and farming. Among the maritime states, maximum production is along the Keralacoast. C.M.F.R.I has conducted demonstration progranunes in open sea and estuarine fanning of mussels by using rack, raft and long line methods. Hatchery production of seed by induced maturation, induced spawning and larval rearing has also been achieved. The method of harvcsting, processing and the nutritional value of mussel meat are given in this paper

GABA from Hypnea valentiae (Turn.) Mont. and its effect on larval settlement of Perna viridis Linnaeus

The crude GABA (ã- amino butyric acid) extracted from Hypnea valentiae collected from Vizhinjam coast was tested for its activity of favouring settlement of pediveliger larvae of Perna viridis by comparing the similar activity of standard commercial grade GABA. The results showed better rate of settlement in 10 ppm followed by 15 ppm standard GABA (100% in 10 ppm and 83.3 % in 15 ppm standard GABA) against only 55 % in both 10 and 15 ppm of crude GABA extracted from the seaweed, whereas the control showed 20.73 % of larval settlement at the end of 48 h. The results are discussed in the light of its advantages and improving its activity through purification of the crude extract
