(1997)Type: Journal ArticleBetween 1989 and 1992, small-scale grow-out trials of cultured Tridacna gigas (L.) were established at 40 coastal villages in Solomon Islands. The juvenile giant clams were delivered to village participants at a mean size ... -
Trends in the farming of the snakeskin gourami (Trichogaster pectoralis) in Thailand
(1997)Type: Journal ArticleThe production of snakeskin gourami (Trichogaster pectoralis) from wild stocks and traditional culture systems has been declining in central Thailand, although they are on the increase in modern culture practices adopted ... -
Fry production of Shire River tilapia Oreochromis shiranus at two broodstock sex ratios
(1997)Type: Journal ArticleOptimal sex ratio in tilapia breeding ponds depends upon stocking density. However, under certain circumstances, altering the male: female sex ratio from a more or less natural 1:1 to 1:2 or even higher has been shown to ... -
Evaluating mortality using length-frequency data when growth parameters are poorly known
(1997)Type: Journal ArticleA method is presented through which the total mortality undergone by several fish stocks of the same species can be compared when growth parameters are poorly known or unknown. Whereas the estimate of Z obtained via the ... -
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 ... -
A computer software package for assessing and managing risks posed by experiments with genetically modified fish and shellfish
(1998)Type: Journal ArticleAssessment and management of risk is needed for sustainable use of genetically modified aquatic organisms (aquatic GMOs). A computer software package for safely conducting research with genetically modified fish and shellfish ... -
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 ... -
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 ... -
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 ... -
Diet and feeding ecology of two sizes of Barbodes gonionotus (=Puntius gonionotus) and Oreochromis sp. in ricefields in Bangladesh
(1998)Type: Journal ArticleFish culture experiments were conducted to compare and evaluate the feeding pattern and strategies, daily ration, gastric evacuation rates, dietary breadth, similarity and overlap of silver barb, Barbodes gonionotus, and ... -
Preliminary studies of locomotion and burrowing by juvenile boring clam, Tridacna crocea
(1998)Type: Journal ArticlePreliminary experiments in Okinawa, Japan, revealed that survival of juvenile Tridacna crocea depends on the size ofthe pit in which it is placed and its locomotory behavior. Juvenile T. crocea, less than 20 mm in shell ... -

(1998)Type: ReportThe major objectives of the DEGITA ( Project (Dissemination and Evaluation of Genetically Improved Tilapia Species in Asia) were: 1) to carry out genetic, socio economic and environmental evaluation of the improved tilapia ... -
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 ... -
Manual on genetic improvement of farmed tilapia (GIFT) research methodologies
(1998)Type: ManualGathering and recording of biological data vital to experiments in a genetic improvement program should be carried out with efficiency, precision and accuracy. This is important in order to avoid marking erroneous conclusion ... -
Can nitrogen pollution from aquaculture be reduced?
(1998)Type: Journal ArticleNitrogen is essential for the normal growth of fish. It is an important ingredient in fish feed but is very expensive. There is evidence that nitrogen loading from feeding and metabolic activities of fish can cause pollution ... -

(1998)Type: ReportThe Project consists of two phases, Phase I focusing on determining research priorities leading to the development of high yielding breeds and strains; documentation of carp genetic resources, documentation of carp genetic ... -
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 ... -
Integrating aquaculture with rice farming in Bangladesh: feasibility and economic viability, its adoption and impact
(1998)Type: ReportStudies were undertaken on 256 farms in Bangladesh from 1992-1994 to assess the feasibility and economic viability of integrating fish culture with rice farming during aman (wet) and boro (dry) seasons in medium highlands. ... -
