On the Use of the Johnson-Schumacher Function to Represent the Relationship Between Length and Fishing Mortality Coefficients
(Training Department, Southeast Asian Fisheries Development Center, 1988-03)
The model is derived under the assumption that within the range of the maximum length and the length at which the fishing mortality is zero, the rate of change in fishing mortality coefficients at ant length is proportional ...
An Assessment of the Interactions between Species in Multispecies Demersal Fisheries in the Southern Part of the Gulf of Thailand
(Training Department, Southeast Asian Fisheries Development Center, 1987-09)
The demersal fisheries in the Gulf of Thailand are a good example of multispecies fisheries which have been studied intensively. Since the early 1960’s, catch per unit of fishing effort (CPUE) statistics, in terms of ...
An Analysis of Catch Curve Using Length Composition Data With Applications to the Lizard Fish (Saurida elongata) in the Gulf of Thailand
(Training Department, Southeast Asian Fisheries Development Center, 1987-04)
Since the beginning of this century a catch curve, which represents the relationship between the size or age of the fish and the logarithms of the frequency of the occurrence of the fish in catches, has long been recognized ...
Estimation of the Bertalanffy Growth Parameters of Fishes in the Gulf of Thailand by Unweighted of Weighted least Squares Methods
(Training Department, Southeast Asian Fisheries Development Center, 1989-05)
Three probabilistic models are postulated under the assumptions that the error terms are additive and that the length variances are constant for all ages in Model 1, the variances are proportional to the square roots of ...
Dynamics of Demersal Fish Communities in the Gulf of Thailand, 1963-1981
(Training Department, Southeast Asian Fisheries Development Center, 1987-02)
The demersal fish stocks In the Gulf or Thailand have been intensively studied since the exploitation of these fisheries started in the early 1960 ‘s. Investigations by otter board trawl have been conducted annually by the ...
