No results found.The Cuban government wish to expand the tourist industry as a sorce of much needed foreign exchange. Opportunites to supply and support the industry are actively being sought and include the provision of fish and shellfish foods from fisheries and aquaculture to supply the hotel and restaurant enterprises throughout the designated tourist areas. The culture of the Giant Freshwater prawn (Macrobrachium rosenbergii) is one such Trials are being made with pond reared stock using three methods to improve breeding; i) eyestalk ablation; ii) photoperiod manipulation; iii) artificial insemination. In the hatchery larvae are fed algae followed by minced clam, squid, marine fish and Artemia but Nippai prepared feeds are also used. A nursery phase is employed lasting 30–40 days which takes the shrimp from 5–10 day old post-larvae to 0.5 to 1.0 g juveniles. Stocking rate is 100/sq m but trials, have been made with 1000–2000 in 70 t tanks. In the on-growing phase shrimp are stocked at 5/m2, feed is given at from 15 to 2.5% per day and salinity is 25%. Feed costs around 200–250 pesos per tonne and contains squid, shrimp meal (from processed P. schmitti caught at sea) and zeolite. Problems with unstable artificial feed are common. Production is around 400–500 kg/ha/cycle and at present there are 1.6 to 1.7 cycles/yr. Newness of the ponds, inexperience and climatic changes are constraints on production. Early trials with P. notialis were not encouraging as growth stopped at 6–8 g, howev er new trials may be undertaken. -

No results found.The farming of the Giant Freshwater Prawn has expanded rapidly in Thailand in recent years. Production has increased from less than 3 tons/year in 1976 to an estimated output of more than 1,200 tons in 1982. This rapid growth was largely stimulated by the Chachoengsao Fisheries Station established in 1976 to solely promote culture of the prawn. Services of the station comprise the production and distribution of post-larvae, without cost to the farmers in 1976 –1978, along with training and exten sion programmes on all phases of Macrobrachium culture. During the initial period of 1976–78, postlarvae were distributed to farmers free of charge. The assistance of UNDP/FAO in 1979–1980 has also contributed much to its rapid expansion. The station has increased its post larvae production from 5.6 million in 1979 to 15 million in 1982. The number of farms and acreage have also increased, from 306 farms with a total area of 300 ha in 1979 to 677 farms of 1,737 ha by 1982. Thailand is still im porting some Macrobrachium, about 700 tons/year chiefly from Burma, but at the present rate of growth, domestic demands will soon be met by local production. Current practices and the improvement made in the culture system in Thailand are reviewed below. -
