Results of the study on the relative safety of nine different pesticides: Diazinon 40% EC, Diazinon 10 G, Elsan 50% EC, Sumithion 50% EC, Furadan 3 G, Padan 50% SP, Kitazin 48% EC, Kitasin 17% G and EPN 45% EC for various fish species: Cyprinus carpio, Labeo rohita, Oreochromis mossambicus, Channa punctata, Clarias batrachus and Anabas testudineus used in rice-fish culture are presented and discussed.
Goldfish, common carp and Nile tilapia were sampled between September 2002 and May 2003 to investigate lesions induced by viral diseases and ectoparasites. Goldfish exhibited neoplasms, Dermocystidium sp., Ichthyophthirius multifiliis (Ich), Trichodina reticulata, Lernaea cyprinacea and systemic infections. Neoplastic and systemic infections in goldfish were associated with viral infection. Oreochromis niloticus and Cyprinus carpio were mainly infested with several species of Trichodina and monogeneans. The presence of Dermocystidium sp.
The WorldFish Aquaculture Research and Training Center is located outside Abbassa, a typical village in Egypt's Nile delta. The WorldFish Center launched its regional research and training activities in 1998. Courses were held in the center from 1999 to 2009. The growth in training over this period reflects the growth in aquaculture in Egypt and globally, the need for trained technicians, and the growing reputation of the Center in this field.
This review is prepared as part of the FAO Project “Environmental Impact Assessment (EIA) and monitoring in aquaculture”. The review provides a compilation, review and synthesis of existing EIA and environmental monitoring procedures and practices in aquaculture in the Asia-Pacific region, the largest aquaculture-producing region in the world. This review, as in other regions, gives special consideration to four areas related to EIA and monitoring in aquaculture including: (1) the requirements (2) the practice (3) the effectiveness and (4) suggestions for improvements.
In this chapter, the author discusses the Farmer-Scientist Research Partnership (FSRP) approach established in Malawi.
The Fisheries Research Institute with the technical assistance of International Center for Living Aquatic Resources Management (ICLARM) has developed low-cost aquaculture practices, through on-station and on-farm research. These studies have shown that farmer's fish productions and incomes could be increased manifold, through appropriate management practices.
The article is a summary of the preliminary results of an AFSSRN-funded study on Risk Programming of Rice-Fish Production Systems in the Philippines conducted early 1993 by the AFSSRN-CLSU team. The results show that rice-fish culture leads to a higher rice production compared to rice monoculture.
Currently there are 2 sources of freshwater prawn Macrobrachium rosenbergii production in Vietnam - natural production from the rivers and canals and aquaculture production from ponds and ricefields. An account is given of the production of this prawn in the Mekong Delta. The prawns are harvested primarily by a common small scale method using shelter traps.
This document is part of a series of 5 technical manuals produced by the Challenge Program Project CP34 “Improved fisheries productivity and management in tropical reservoirs”. The Water Research Institute (WRI) in Akosombo, Ghana, is working to bring cage aquaculture technology to smallholder farmers. The stocking, feeding and cage-construction technology piloted by WRI is now being widely adopted in the Lower Volta basin in Ghana. The results of WRI research over the period 2005-2009 are presented here as a guide to potential investors.
Aquaculture has become the fastest growing sector of food production in the world. Despite the encouraging trends, several constraints have a negative impact on the growth of aquaculture. Among those, diseases are the primary limiting factors. Bacterial diseases are responsible for heavy mortality in both wild and cultured fish. Antibiotics are used to control such infection but may result in development and spread of antimicrobial-resistant bacteria and resistance genes and occurrence of antimicrobial residues in fish tissues.
