Two phases of growth can sometimes be distinguished in long-lived fish species. The first involves the growth of zooplankton-feeding juveniles and young adults. The second consists of accelerated growth of large, piscivorous ...
Length-weight relationships of fishes from tributaries of the Volta River, Ghana: Part II and Conclusion
Type: Journal Article
Slopes and intercepts of length-weight relationships obtained from 37 populations from the rivers Oti, Pru and Black Volta in Ghana were compared using a one way analysis of covariance with fixed effects. Although no ...
Growth, mortality and length-weight parameters for some Kuwaiti fish and shrimp
Type: Journal Article
As a (small) contribution toward reestablishing communication between Kuwait-based fishing research and other research conducted elsewhere in the tropics, the growth parameter estimates and the "a" and "b" values ...
Time recovery for exploited fish populations based on surplus yield models
Type: Journal Article
A new method to estimate the time recovery of exploited population based on M.B. Schaefer's theory is proposed. The parameters used as follows: current population size (alphaP sub( infinity )'), target population level ...
Growth, mortality and recruitment of Decapterus kurroides in Davao Gulf, Philippines

Type: Journal Article
Details are given of a framework for developing breeding programmes using experience from the Genetic Improvement of Farmed Tilapias project which focussed on Nile tilapias (Oreochromis niloticus ). The following aspects ...
Diet and feeding ecology of two sizes of Barbodes gonionotus (=Puntius gonionotus) and Oreochromis sp. in ricefields in Bangladesh
Type: Journal Article
Fish 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 ...
Changes in consumer tastes in the demand for fish and meat in Malaysia
Type: Journal Article
In this article the demand for fish and its substitute was estimated using a very flexible demand function, the Almost Ideal Demand System (AIDS) developed by Deaton and Muelllbaeur (1980), incorporating the habit formation ...
