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

Seed production of the Sand lobster Thenus orientalis(Lund)

Lobsters are among the most priced seafood delicacies enjoying a special demand in international markets. As against a world average annual productio'n of2.1 lakh tonnes, India's average annual lobster production is about 2000 tonnes. 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. 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 scylla rid lobster (Thenus orientalis)

Diet composition and food habits of demersal and pelagic marine fishes from Terengganu waters, east coast of Peninsular Malaysia

Fish stomachs from 18 demersal and pelagic fishes from the coast of Terengganu in Malaysia were examined. The components of the fishes’ diets varied in number, weight, and their frequency of occurrence. The major food items in the stomachs of each species were determined using an Index of Relative Importance. A conceptual food web structure indicates that fish species in the study area can be classified into three predatory groups: (1) predators on largely planktivorous or pelagic species; (2) predators on largely benthophagous or demersal species; and (3) mixed feeders that consume both pelagic and demersal species

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

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

Taxonomy, Biology and Distribution of Lobsters

Lobsters are among the most prized of fisheries resources and of significant commercial interest in many countries. Because of their high value and esteemed culinary worth, much attention has been paid to lobsters in biological, fisheries, and systematic literature. They have a great demand in the domestic market as a delicacy and is a foreign exchange earner for the country

Mariculture nutrition research at CMFRI

Mariculture is now accepted as an alternative to augment marine fish production in the backdrop of dwindling capture fisheries. CMFRI has prioritized mariculture research in three areas which are marine food fish production, production of high value marine cru staceans, and ca ptive breeding and propagation of selected marine ornamental fishes for breeding and conserva tion

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

Overview of lobster farming- Winter School on Recent Advances in Breeding and Larviculture of Marine Finfish and Shellfish

Lobsters are high valued seafood with well established export markets around the world and form extremely important fisheries in many countries. World’s production of palinurid lobsters mostly originate from Australia, New Zealand, Cuba, Brazil, South Africa, USA and Mexico. The annual world catch of lobsters is 2, 33,825 t (2005) valued at US $ 2108 million. Total landing of spiny lobsters is 71925 t (2004)
