The maintenance of reference populations of Tilapia is discussed, examining genetic considerations to be taken into account to conserve the gene pool to prevent genetic drift and prevent detrimental levels of inbreeding. The importance of knowledge of the proper effective breeding number and its use in management of the reference population is described.
This report is a literature review on Food and Nutrition Security in Timor-Leste based on data from surveys conducted by the Timor-Leste National Statistics Directorate, as well as from national and international organizations working in Timor-Leste. This review was supported by the Australian Centre for International Agricultural Research (ACIAR)-funded project “Strategy for Investment in Fisheries in East Timor”.
Fisheries and fish supply are undergoing a fundamental structural transition, as indicated by a ten country analysis. Aquaculture now provides around half the fish for direct human consumption and is set to grow further, but capture fisheries continue to make essential contributions to food and nutrition security throughout the global South. Capture fisheries provide diverse, nutritionally valuable fish and fish products which are often culturally preferred and easily accessed by the poor.
This working paper is an attempt to distil what is known currently about the likely impacts of climate change on the commodities and natural resources that comprise the mandate of CGIAR and its 15 Centres. In this WorldFish contribution, a summary is given on the importance of fisheries and aquaculture on food nutrition and security.
The results are presented of a 2-year study conducted regarding management practices and problems associated with raising fish in concrete tanks in Nigeria. The location and construction of the tanks, which were used toculture Clarias gariepinus, Tilapia guineensis and Heterobranchus bidorsalis , are described, and suggestions made for overcoming the problems involved, which were mainly due to poor management skills. Major problems identified included incidence of "broken skull" disease in C.
The criteria applied by a development bank in taking investment or financing decisions rely basically upon thesocioeconomic merits of the investment project. Financing projects and mechanisms regarding fisheries andaquaculture are outlined.
Experiments were conducted on the feeding habits of Mugil so-iuy fry under rearing conditions in order to obtain information of use in enhancing survival during development stages.
The Feed the Future Aquaculture project is a five year transformative investment in aquaculture focused on 20 southern districts in Barisal, Khulna and Dhaka divisions, Bangladesh, which started in October 2011. This report describes the achievements of FtF-Aquaculture project activities implemented during the 6th quarter (January to March 2013) along with cumulative progress on FtF indicators. Due to the seasonality of fish and shrimp production, which is out of sync with the project year, final harvesting of aquaculture production was completed in this quarter.
Increases in fish demand in the coming decades are projected to be largely met by growth of aquaculture. However, increased aquaculture production is linked to higher demand for natural resources and energy as well as emissions to the environment. This paper explores the use of Life Cycle Assessment to improve knowledge of potential environmental impacts of future aquaculture growth. Different scenarios of future aquaculture development are taken into account in calculating the life cycle environmental impacts.
This document presents ex-ante impact evaluations of research for development projects related to aquaculture in Bangladesh, Malawi and Ghana. The Ghana chapter also includes an ex-ante evaluation of a fisheries project. The case studies utilized preliminary versions of guidelines developed specifically for ex-ante evaluations of aquaculture and fisheries projects. The guidelines, found in A Practical Guide for Ex-Ante Impact Evaluations in Fisheries and Aquaculture, are designed to provide an approach for a qualitative examination of the potential for a project to deliver impacts.
