A note on the development of a new software package, the FAO-ICLARM stock assessment tools (FiSAT)
Type: Journal Article
A brief narrative is given of the background of a new FAO-ICLARM software for (mainly length-based) fish stock assessment, the FAO-ICLARM Stock Assessment Tools or "FiSAT" package, integrating the ICLARM's Compleat ELEFAN, ...
Biochemical and morphometric approaches to characterize farmed tilapias
Type: Journal Article
Biochemical (electrophoresis and mitochondrial DNA) and morphological analysis are important tools for the characterization of strains. Reference is made to studies conducted in the framework of the Genetic Improvement of ...
Population dynamics of Saurida elongata and S. undosquamis (Synodontidae) in the southern Gulf of Thailand
Type: Journal Article
Length-frequency data on Saurida elongata and S. undosquamis (Synodontidae) from bottom trawl survey conducted in 1984 in the Southern Gulf of Thailand were analyzed using the Compleat ELEFAN software. The seasonal pattern ...
Estimation of yield per recruit when growth and fishing mortality oscillate seasonally
Type: Journal Article
A general form of the yield equation is presented. This is used to investigate the effects of seasonal growth oscillations on estimation of yield per recruit. The results show that these effects will be strongest in ...
Growth performance in fishes: rigorous description of patterns as a basis for understanding causal mechanisms
Type: Journal Article
The origins and features of the growth performance index Phi ' are reviewed, emphasizing its ability to express the underlying common characteristics of a family of growth curves. Some other aspects of Phi ' are discussed, ...
Growth of Pomadasys kaakan (Haemulidae) off the coast of Pakistan
Type: Journal Article
The growth parameters of javelin grunter Pomadasys kaakan (=P. hasta, Haemulidae) were estimated from length-frequency samples collected from December 1988 to February 1989 along the Pakistan coast. They are L sub( infinity ...
Tabular data on marine fishes from Southern Africa. Part 1: Length-weight relationships
Type: Journal Article
The parameters a and b of length-weight relationship of the form W = aLˆb were computed for 122 species from graphs presented in R.van der Elst's "Guide to the Common Sea Fishes of Southern Africa".
Population control in farmed tilapias
Type: Journal Article
Under the majority of culture practices, the reduction or elimination of reproduction in culture ponds results in significantly improved yields of marketable fish. An examination is made of existing methods for the control ...
Supply response functions of two fish species in the Arabian Gulf area
Type: Journal Article
A polynomial distributed lag model was fitted to monthly fish production data from the Arabian Gulf, Saudi Arabia, inorder to determine the nature of the lagged output response resulting from a change in fish price. Results ...
On length-weight relationships. Part II: Computing mean weights from length statistics
Type: Journal Article
Assuming a known length-weight relationship, the formula for calculating the mean weight from grouped length statistics is recapitulated. Then a simple analytical method for calculating mean weight from basic length ...
