Value of river fisheries

This paper examines the importance of accurately valuing the fisheries of large rivers (and in all ecosystems) and how such information can be used to maintain, improve and develop inland fisheries and ecosystem services, from both the exploitation and conservation perspectives, for future generations.

Utilization of trawl bycatch in Gujarat (India)

Bycatch from trawlers forms a signifi cant quantity of the total marine fi sh landings along the northwest coast of India, particularly in the state of Gujarat, which contributes about 23 percent of the total marine fi sh landings in the country. This paper discusses the composition of this bycatch, its significance in terms of nutritional value, its present utilization pattern and the scope for improvement.

Use of hapas to produce Nile tilapia (Oreochromis niloticus L.) seed in household foodfish ponds: a participatory trial with small-scale farming households in nothwest Bangladesh

Production and supply of fish seed-stock are essential for the promotion of aquaculture. Traditional inland aquaculture was based on the collection of seed-stock from rivers and required the sorting and acclimatising of mixed species. Fine meshed nylon net cages ‘hapas’ have been used for this purpose for Chinese carps in China and in Bangladesh and India for Indian major carp for a long time. Hapa nursing of small fry to larger, more predator-resistant fingerlings has been the focus for intensification of aquaculture in North East Thailand and Lao PDR.

Use and exchange of aquatic genetic resources for food and aquaculture: clarias catfish

There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly US$400 million in 2006. Most production involves the African Clarias gariepinus (Burchell, 1822) and three Asian species, Clarias batrachus (Linnaeus, 1758), Clarias macrocephalus (Günther, 1864) and Clarias fuscus (Lacep'de, 1803). In much of Asia, hybrids of introduced C.

Updating names, distribution and ecology of riverine fish of Kenya in the Athi-Galana-Sabaki river drainage system.

Few studies of the riverine fish of the Athi-Galana-Sabaki river drainage area in Kenya have been carried out since the last comprehensive surveys of the 1950s and early 1960s. This paper presents updated information on scientific and recommended common names, distribution and ecology of selected fish species of this catchment. At least 28 riverine fish families consisting of 46 genera and 62 species occur in the drainage system, of which, 39 species are strictly freshwater (4 introduced) while 23 species are of marine origin.

Understanding livelihoods dependent on inland fisheries in Bangladesh and Southeast Asia: Vietnam PRA report

During the period of May to July 2002, An Giang University, in conjunction with the Chau Phu, Thoai Son and Chau Doc District People's Committees, and Can Tho University conducted Participatory Rural Appraisals (PRAs) in four different Provinces. The research findings from this study are presented in this report. The purpose of this exercise was to better understand the livelihoods of people living in rural areas and depending mainly on inland capture fisheries.

Understanding livelihoods dependent on inland fisheries in Bangladesh and Southeast Asia: final technical report

The Department for International Development (DFID) through the Marine Resources Assessment Group (MRAG) has approved the project proposal for the Project Memorandum on “Understanding Livelihoods Dependent on Inland Fisheries in Bangladesh and South East Asia” based on an earlier concept note on the same topic. The project characterizes the poor, identifies their dependence upon aquatic resources, describes the nature and status of those resources, and emphasizes the vulnerability of the poor to loss or mismanagement of these resources.
