Influence of symbiont strain on early growth of tridacnids
Type: Journal Article
Symbiotic algae (zooxanthellae) from the mantles of fast- and slow-growing Tridacna gigas, from T. maxima, T. crocea and Hippopus hippopus were isolated and supplied to larvae of T. gigas grown under hatchery conditions. ...
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".
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 ...
Population parameters of Sardinella species in the coastal waters of Dar es Salaam, Tanzania
Type: Journal Article
Population parameters of Sardinella species from the artisanal purse seine and ring net fisheries of the Dar es Salaam area, Tanzania, were investigated based on length-frequency data, analyzed with FAO's LFSA and ICLARM's ...
Exemple de la contribution de l'analyse fsctorielle des correspondences pour suivre l'evolution de la structure d'une population piscicole
Type: Journal Article
This contribution demonstrates an application of correspondence analysis to length-frequency data of catfish (Ictalurus melas, lctaluridae) sampled by electrofishing in the Garonne River, near Toulouse, France. The available ...
Some population parameters of commercially-important fishes in the Philippines
Type: Book
The estimates of the von Bertalanffy Growth Function (VBGF) parameters and mortality parameters (Z and M) for some of the commercially-important species caught in the Philippine waters are presented using the FAO-ICLARM ...
Growth, mortality and recruitment of short-wing flying fish Oxyphorhampus micropterus in Bohol Sea, Philippines
Type: Journal Article
The von Bertalanffy growth parameters (L8 and K) were estimated, based on length-frequency data from the small scale fishery, and the Compleat ELEFAN software, for short wing flying fish Oxyphorhampus micropterus (Hemiramphidae) ...
Growth and mortality of Indian mackerel Rastrelliger kanagurta (Scombridae) in the Visayan Sea, Central Philippines
Type: Journal Article
The growth of Indian mackeral Rastrelliger kanagurta in the Visayas Sea, central Philippines, is estimated, based on length-frequency data from 1983 to 1987 and the Compleat ELEFAN program. Results are TL8 = 38 cm and K = ...
Growth, mortality and recruitment of Omani abalone (Haliotis mariae)
Type: Journal Article
Historical length-frequency data of Oman abalone (Haliotis mariae) from two areas (Sadh and Hadbin) of the Dhofar coast of the Sultanate of Oman were used to estimate growth parameters by nonlinear least square fitting. ...
