Status of crustacean fishery resources -Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008
From the economic and industrial point of view, edible marine crustaceans consisting of shrimps,
lobsters are the most important constituents of the commercial fish landings in the country. Major portion
of the landings was exported in various product forms. Investigations on resources and biology of shrimps,
lobsters and other important crustaceans were initiated at the CMFRI in 1947 and since then, valuable data
had been collected. Information on catch and effort, composition of landings, species-wise details on age
and growth, food and feeding, maturation and spawning, migration and population characteristics for shrimps,
lobsters and crabs were collected from fish landing centers along the Indian coast. This voluminous database
has provided a strong foundation for assessment of edible crustacean stock, so as to suggest appropriate
regulatory measures for effective management of these resources. A comprehensive account on the fishery
and biological characteristics on edible crustaceans, and management options for their optimum exploitation
based on the research carried out by CMFRI is presented here
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. WorldтАЩs 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)
Lobster farming in India
Spiny or rock lobsters are low volume and
high value fisheries which support some of the
most valuable marine resource worldwide. India,
earns an approximate US $ 15 million each year
through export of lobsters, mostly to Southeast
Asian countries and Japan, although less than,
3,000 tonnes is landed annually. The potential for
increasing the yield from the wild fisheries is
limited, as the stock is subjected to extreme fishing
pressure and is nearing their long term equilibrium
yield. Hence, the most imaginative management
strategy seems to be increasing the production
through population enhancement and aquaculture.
Recent success in rearing the phyllosoma larvae,
has significantly improved the chances of captive
breeding and seed production in spiny lobsters
Review of prospects for lobster farming
Capture fisheries have reached a peak in production, and
stock enhancement or aquaculture appears to be the only
hope of meeting the ever increasing demand for high value
seafood like lobsters. For aquaculture, the pressing need is to
solve the dilemma of promoting expansion while at the same
time demanding the development of environmentally sound
technologies and farming practices (Mace, 1997). Lobsters have
excellent market demand and price and especially live lobsters
are the most preferred. Customers in affluent countries are ready
to pay more for fresh seafood. Lobsters are exported in different
forms; live, frozen tails, whole frozen, whole-chilled, wholecooked
and frozen and as lobster meat. The live lobster trade
increased from 1.3 % during 1993-94 to 12.7% during 2003-
04 period
Commercial prospects for farming spiny lobsters
Tropical spiny lobsters are fast growing and highly adaptable to captive condition
Lobster Fishery and Management
Lobsters are one of the highly priced crustaceans in India and are in great demand as a delicacy in the internal market and as a foreign exchange earner in export market. Gourmets the world over prize this crustacean as the most delectable. As a result, lobsters are now fished indiscriminately and the population at least in certain areas is threatened. Most females either don't get a chance to reproduce or are caught while they are breedin
Breeding and hatchery technology development of spiny lobsters and crabs - a review
Though maturation and breeding of spiny lobsters have been successful under captivity, prolonged larval phase of
spiny lobsters has been the major constraint for seed production. Protracted larval phase ofthe spiny lobster poses several problems. In India, larvae of Panulirus homarus were reared upto the 7th stage in 60 days. Partial success has been achieved in the larval culture of P. polyphagus and P. ornatus also. However, morc information on the appropriate food for different larval stages, the feeding behaviour and optimum water quality requirements for faster
moulting and growth of the larvae is required for successful development of lobster hatchery technology
Co-management: an alternative approach to lobster fisheries management
Stagnation in marine fisheries sector has prompted fishery
managers to think of an alternative fisheries management strategy
where both government agencies and fishing communities
participate in decision making, exercise authority and share
responsibility
Removal of nitrogenous wastes by seaweeds in closed lobster culture
The experiment shows that the seaweeds Gracilaria sp. can be used in maintaining water quality in closed culture systems by ready uptake of nitrogenous wastes excreted by the cultured organisms. The advantages of water reuse systems incorporating biological agents such as seaweeds for water management in closed systems
