An objective method for determining fish growth from length-frequency data
Type: Journal Article
A computing procedure was devised, to determine fish growth, that traces through a series of length frequencysamples sequentially arranged in time, a multitude of growth curves, and then selects the single curve which best ...
On the interrelationships between naturual mortality, growth parameters, and mean environmental temperature in 175 fish stocks
Type: Journal Article
A compilation of values for the exponential coefficient of natural mortality (M) is given for 175 different stocks of fish distributed in 84 species, both freshwater and marine, and ranging from polar to tropical waters.
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 ...
The relationships between gill surface area and growth performance in fish: a generalization of von Bertalanffy's theory of growth
Type: Journal Article
This paper is an attempt to interpret some of the data on fish growth available in the literature, emphasis is being given to a reassessment of von Bertalanffy's theory of growth as applied to fishes.
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, ...
Tabular data on marine fishes from Southern Africa. Part II: growth parameters
Type: Journal Article
This contribution presents von Bertalanffy growth parameter estimates for 28 species of marine fishes derived from growth curves in R. van der Elst's "Guide to the Common Sea Fishes of Southern Africa".
The population dynamics of Nemipterus marginatus (Cuvier & Val.) off western Kalimantan, South China Sea
Type: Journal Article
The following parameter values are derived for a West Kalimantan (West Borneo) stock of the threadfin bream, Nemipterus marginatus : L infinity = 24.5 cm (L.T.), W infinity = 210 g, K = 0.42, t = -0.41 and M = 1.73. ...
Growth, reproduction and mortality of the sea hare Dolabella auricularia (Gastropoda: Aplysiidae) in the Central Visayas, Philippines
Type: Journal Article
The growth parameters W infinity and K of the von Bertalanffy growth equation were estimated from size-frequency data of the sea hare D. auricularia using an objective, computer-based method. The results obtained from two ...
A simple method for estimating the food consumption of fish populations from growth data and food conversion experiments
Type: Journal Article
A multiple-regression extension of the basic model is presented which accounts for the impact of factors other than body weight on values of K1 and p. This method is illustrated with an analysis of data on dab (Limanda limianda).
