Book (stand-alone)The potential of farming tilapia (Oreochromis niloticus) and freshwater prawn (Macrobrachium rosenbergii) in Vanuatu 2004
Also available in:
No results found.Under the auspices of the Food and Agriculture Organization of the United Nations (FAO) Sub-Regional Office for the Pacific Islands (SAPA) in Samoa, a feasibility study on farming tilapia and prawns was undertaken by SPC Aquaculture Office in November 2003. The objectives were to survey the potential to develop Tilapia (Oreochromis niloticus) and Prawn (Macrobrachium rosenbergii) farming in Vanuatu (further details are given in the Terms of References in Appendix 2). -
ProjectFeasibility Study and Piloting of Farming of New Shrimp/Prawn and Fish Species in Punjab and Sindh Provinces - TCP/PAK/3710 2022

No results found.Aquaculture is increasingly recognized as a means of improving food security, reducing poverty, and providing a source of employment for rural communities In Pakistan, the fish sector constitutes approximately one percent of employment In recent years, aquaculture has gradually become an important component of this sector, with potential for further development in the country Most of the surface area cultivated for fish farming, totalling between 200 000 and 300 000 acres, is located in Punjab and Sindh provinces Shrimp farming, in comparison, is not yet a common practice in Pakistan Over a period of time, due to proactive government policies, interest in aquaculture among the private sector and local farmers has significantly increased The country’s water resources and the range of ecological habitats store the potential for scaling up these farming practices To do so, careful and thorough assessments of environmental conditions, appropriate fish and shrimp species and the viability of aquaculture technologies need to be conducted. -

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.
