Larval and juvenile rearing of the sand lobster Thenus orientalis Lund, 1793- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Over the last fifty years, global aquaculture production has undergone remarkable changes, with production scaling up from less than a million tonnes in the early 1950s to 48.1 million tonnes in 2005. China contributed to 67.3% of the production, followed by India with 5.9%. Aquaculture now accounts for nearly 45% of the world’s food fish supply, and this share is expected to reach 50% in 2015 (FAO, 2007). Mariculture is a relatively virgin field with continuous scope for diversification and its ultimate aim is always to enhance high value sea food production through ecofriendly, cost-effective technologies. The present annual mariculture production in India is about 7000t, which is estimated to reach about 1 lakh tonnes in 2020

Open sea cage farming of Asian sea bass Lates calcarifer in the Bay of Bengal, off Chennai- National Training on Sea cage farming- 2010

Controlled captive culture of fin fishes in open water bodies (seas, reservoirs, lakes) is mostly done in pens and cages. Open sea cage culture of the Asian sea bass Lates calcarifer ,was carried out for the first time in the Bay of Bengal off Chennai by CMFRI during February - August 2010. The execution of the programme began with the fabrication of suitable cages with proper accessories, identification of site, procuring and nursery rearing of seed, transportation and stocking of fingerlings and open sea rearing till harves

Hatchery Technology and Seed Production of Lobsters

Lobsters are high-value seafood delicacies commanding high demand in international markets, with a high culinary value attached and lobster tails are always in great demand world-wide. Freshwater crayfishes, which are considered a delicacy in many parts of the world, are a favourite aquaculture candidate in North America, Europe and Australia. Crayfish and rock lobster aquaculture practices are initially capital oriented but deliver high production and income turnover in the long run. This industry has already taken off in countries like the U.S.A. and Australia. The lobster fishery in India is supported by two groups of lobsters – the spiny lobsters (Palinurus homarus, P. polyphagus, P. ornatus and P. versicolor) and the scyllarid lobster (Thenus unimaculatus). Lobster culture in India is still in the infancy stage. With the distinction of being perhaps, the only seafood resource in India’s trade economy, which remains relatively low down the ladder in terms of quantity of production but brings in maximum foreign exchange, lobsters have been the subject of study for more than two decades now and C.M.F.R.I. has been spearheading research in the development of culture technologies for different species of lobsters

Culture potential of the sand lobster Thenus orientalis (Lund)

Complete larval development of the scyflarid lobster Thenus orientalis was achieved for the first time in India at the Kovalam Field Laboratory of CMFRI. There has been only one other earlier report of a similar achievement in T. orientalis from Australia. Sub-adult male and female T. orientalis collected from the wild matured and mated in captivity Larvae (phyflosoma) were reared in treated seawater of salinity 37-39 ppt and pH 8-8.2 and fed on a combination of fresh clam meat and live zooplankto

Broodstock development and captive breeding of sand lobster Thenus orientalis lund, 1793- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Lobsters are among the largest marine arthropods, with a long life span. They are slow growing animals with a complicated and prolonged life cycle, which greatly increases the risk of stock depletion through indiscriminate fishing. Sand lobsters are known to inhabit the open unconsolidated sediments between the coast and adjacent reefs and further beyond. These animals prefer soft, muddy beds. They are nocturnal feeders, with specific predatory feeding habits. Unlike the spiny lobsters, they swim actively and cover large distances while foraging for food. Gross morphological modifications including dorsoventral compression of the body, lateral expansion of carapace and extreme reduction of antennae and body spines have resulted in a well streamlined, energy-efficient swimming shape. An insight into the reproductive biology of an animal is a preliminary requisite for broodstock development and breeding in captivity. The intricate processes underlying the actual phenomenon of propagation of a species usually begin at the formative phase of the individual. They however manifest as visible changes at a later phase of growth, commonly acknowledged as the “adult” or “sexually mature” phase. These processes include a number of anatomical, physiological, morphological and behavioral changes

Sand Lobster Thenus unimaculatus (Burton and Davie 2007)

Sand lobster is distributed in Indian Ocean from West to East and is one of the most promising candidates for lobster aquaculture in India

Black porpoise Neophocena phocaenoides, G. Cuvier landed in a dol net at Seemar, Gujarat

A black porpoise, Neophocaena phocaenoides Gi Cuvier was caught in a dol net operating off Seemar bunder, Gujarat. The animal is locally called "Gonio." Local enquiry revealed that though there is no regular or targeted fishery for dolphins or porpoises, there have been stray occurrences of these mammals being captured by dol nets operated in the area. The nets {16 m long) are usually operated at a depth of 8 m. The locals utilize the oil extracted from these animals for application on their wooden boats
