Low cost breeding and hatching techniques for the catfish (Heteropneustes fossilis) for small-scale farmers
(1998)Type: Journal ArticleThe high demand for the stinging catfish (Heteropneustes fossilis) and declining wild stocks led the Centre for Aquaculture Research and Extension of India to look for methods for the culture of the species. This paper ... -
Effect of fishpond input on pond mud nutrient levels in integrated crop-fish culture resource recycling
(1998)Type: ReportThe success of aquaculture among small holder farmers in Malawi, depends on the use of the available on-farm resources. Commercial fish feeds are currently not available. Fish ponds open possibility for recycling of waste ... -
Effect of transportation stress on hepatic glycogen of Oreochromis niloticus (L.)
(1998)Type: Journal ArticleOreochromis niloticus was subjected to transportation stress to investigate hepatic glycogen levels and mortality as indices of stress. Mortalities lasted up to three days after transportation, except in highly aerated ... -
Observations on gillnet catches of Kariba tilapia, Oreochromis mortimeri from Bumi Basin of Lake Kariba, Zimbabwe
(1998)Type: Journal ArticleGillnet catches of Oreochromis mortimeri (Trewavas) were studied in the Bumi Basin of Lake Kariba in 1988 and 1989. Total length (TL) was positively correlated with standard length (SL). The linear relationship between TL ... -
Efforts to save the marine environment in Tanzania
(1998)Type: Journal ArticleThe Tanzanian marine environment has been under threat for quite a long time now due to human activities. With the establishment of the Marine Parks and Reserve Act in 1994, several areas have been earmarked as marine ... -
The evolution of body muscle composition of the African catfish (Clarias gariepinus) (Burchell 1822)
(1998)Type: Journal ArticleChanges in body muscle composition of Clarias gariepinus were studied in fish reared from 1.08 g to 383 g mean body weight in a 201-day culture period. Changes in the amount of protein content, dry matter and ash free dry ... -
Making experiment station results more useful to African fish farmers
(1998)Type: Journal ArticleRather than using more or less ideal conditions for setting experimental controls, the use of conditions similar to those likely to be encountered by farmers should produce research results which are realistically achievable ... -
Policy imperatives for sustainable aquaculture development in Asia: lessons from Bangladesh, the Philippines and Thailand
(1998)Type: Conference PaperThe main objective of this paper is to identify an appropriate policy framework for the development of aquaculture and its contribution to overall economic development. The second section of this paper examines the performance ... -
Integrated poultry-fish farming: a way to increase productivity benefits
(1998)Type: Book ChapterThe integration of aquaculture with poultry results in a more efficient use of resources than is possible with aquacul-ture farming alone. Other benefits of diversification include a reduction in the risk of total crop ... -
Polyculture of carps in integrated broiler-cum-fishfarming systems
(1998)Type: Book ChapterA study was undertaken to determine fish species combinations that would result in optimum production levels in integrated broiler raising systems. Its objectives were: (i) to evaluate the production potential of fish in ... -
The potential for crop rotation in controlling diseases in shrimp culture
(1998)Type: Journal ArticleThe use of antibiotics and other chemicals in controlling shrimp pathogens become ineffective as the strains grow more resistant to these chemicals. Moreover, the bacterial pathogen (Vibrio harveyi) produced biofilm coating ... -
USAID_Scaling nutrition-sensitive fisheries technologies and integrated approaches through partnership in Odisha_Annual Report Oct 2017-Sept 2018
Type: Donor ReportThe annual report (Oct 2017-Set 2018) provides details of all activities undertaken under the 4 thematic areas (increased availability, increased accessibility, increased consumption and scaling) of the project, results ... -
Integrated smallholder agriculture aquaculture in Asia: optimizing trophic flows
(1999)Type: Book ChapterA nutrient modelling approach was applied to show how the combination of crops, trees, livestock, and fish, that is, integrated agriculture-aquaculture (IAA), helps in optimizing trophic flows in Asian rice-based agroecosystems. ... -
Responses to bi-directional selection for frequency of early maturing females in Nile tilapia (Oreochromis niloticus)
(1999)Type: Journal ArticleThe present study was carried out to investigate a simple method for recording the occurrence of early maturing females in Nile tilapia at a fixed time after stocking and to estimate the response to bi-directional selection ... -
Response of two generations of selection to increased body weight in channel catfish, Ictalurus punctatus, compared to hybridization with blue catfish, I. furcatus, Males
(1999)Type: Journal ArticleTwo generations of selection for increased body weight in Kansas (AU-KS-2) and Marion (AU-MS-2) lines of channel catfish, Ictalurus punctatus, resulted in a 12% and 11% increase in body weight at market size, respectively. ... -
The good, the bad, and the ugly: a critical look at species and their institutions from a user's perspective
(1999)Type: Journal ArticleOver the past eight years my colleagues and I have been involved in a major project to make key information on fishes available to users, especially in developing countries. There are about 25 000 species of fishes in the ... -
Study on feeding habits of Piaractus mesopotamicus (Pacu) larvae in fish ponds
(1999)Type: Journal ArticleA limnological study of the artificial fish pond and an analysis of the stomach contents of pacu (Piaractus mesopotamicus) larvae of 2 to 45 days age were made for a period of 45 days to evaluate their feeding preferences. ... -
