New functions for the analysis of two-phrase growth of juvenile and adult fishes, with application to Nile perch
Type: Journal Article
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 ...
Growth and mortality of snapper Etelis carbunculus in Vanuatu
Type: Journal Article
This paper presents estimates of the parameters L8 and K of the von Bertalanffy equation, as obtained from length-frequency data on the lutjanid Etelis carbunculus from Vanuatu, analyzed using teh Compleat ELEFAN software. ...
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 ...
Notes on the silverbiddy Gerres oyena (Gerreidae) in Tarawa Lagoon, Kiribati
Type: Journal Article
Length-frequency data, collected using beach seines, on the common silverbiddy Gerres oyena (Gerreidae) in Tarawa Lagoon, Kirbati (northern Gilberts Group), from September 1976 to October 1977 were analyzed using the ...

Growth, mortality and recruitment of Decapterus kurroides in Davao Gulf, Philippines
Type: Journal Article
The ringnet fishery off Davao, southern Philippines, is briefly described. The major species (36%) in the catch is Decapterus kurroides (Pisces, Carangidae), whose growth parameters and mortality rates (natural and fishing) ...
Concurrent rice-fish trials: comparing regular and border planting patterns
Type: Journal Article
Details are given of experiments conducted at the Freshwater Aquaculture Centre at Munoz, Philippines, to investigate the effects of varying the rice planting pattern on fish yields in integrated rice field aquaculture ...
The relationship between maximum and asymptotic length in fishes
Type: Journal Article
The case is made, based on growth curves and other data on Kuwait fishes, that the maximum length in a population does not provide a reliable approximation of asymptotic length.
