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. -

Also available in:
No results found.This working paper represents those parts of my consultants' report to FAO, for the period 20 August – 24 September 1979, which relate to the Programme for the Expansion of Freshwater Prawn Farming in Thailand (Project THA/75/008). Full details of all the techniques and units utilised can be found in an earlier report published by the South China Sea Fisheries Programmea. The primary reason for visiting Bangkok was to help in solving problems of unsatisfactory water in Macrobrachium hatchery s ystems. Methods of abstracting pre-filtered sea water from the natural bed were taught and had already been applied before the visit ended. The technique of using both Village Units, for primary filtration, and Mini-Units, for recirculation, in wholly artificial beds, was shown in Chacheongsao: in this case also a permanent source was created and this had been supplying clean water for some four days before the mission ended. Abstraction from insitu beds is clearly impossible on the vast Centr al Plain, where the canal's base usually consists of almost bottomless mud. For the numerous isolated communities who still take much of their household water from these canals it seems that the mini-Unit methods could bring much improved water at minimal cost. Throughout this region there are numerous fish ponds. While it can hardly be economic to filter the whole supply it seems that the general method described below under “Chacheongsao Fisheries Station” could well be used for that part of t he supply needed for the actual hatchery and the early fry stages, as well as for any sensitive species that might be kept.
