A reassessment of equations for predicting natural mortality in Mediterranean telosts
Type: Journal Article
This brief article presents new empirical models for prediction of natural mortality (M) from growth parameters (L and K, W and K) in Mediterranean teleosts, based on 56 data sets presented in an earlier paper in the January ...
Seasonal variations of growth pattern and condition of Paradise threadfin Polynemus paradiseus (Polynemidae) from Tetulia River in Southern Bangladesh
Type: Journal Article
The Paradise threadfin, Polynemus paradiseus is a marine fresh and brackish water fish species of the family Perciformes. This fish is found in Bangladesh, India, Malaysia, Myanmar, Thailand, Pakistan and Cambodia. Only ...
Conservation for sustaining livelihoods: Adaptive co-management of fish no-take zones in the Mekong River
Type: Journal Article
A major challenge in natural resource management in developing countries is to pursue conservation objectives while avoiding negative impacts on local livelihoods. Inland capture fisheries provide opportunities to demonstrate ...
Using eye lens diameter as age indicator of young Lithognathus mormyrus and Diplodus vulgaris
Type: Journal Article
Eye lens diameter was analyzed in two sparid fish species, Lithognathus mormyrus and Diplodus vulgaris, in order to determine the possibility of using these data for age determination. The results showed that the technique ...
Can the age of the tropical species be determined by otolith measurement?: a study using Pristipomoides filamentosus (Pisces: Lutjanidae) from the Mahe Plateau, Seychelles
Type: Journal Article
The sagittal otoliths of bluespot jobfish (Pristipomoides flamentosus) from the Mahe Plateau, Seychelles, were examined for growth rings using light microscopy. Banding with putative annual and monthly frequency were ...
Growth, mortality and recruitment of Nile perch Lates niloticus (L. Centropomidae) in the Nyanza Gulf of Lake Victoria: an evaluation update
Type: Journal Article
A reassessment of the estimates of growth, mortality and recruitment patterns of Nile Perch, Lates niloticus was made based on data from commercial landings collected during the Catch Assessment Survey Programme. Two sets ...
Empirical equations for the estimation of natural mortality in Mediterranean teleosts
Type: Journal Article
Empirical relationships were established linking estimates of the instantaneous rate of natural mortality (M), the von Bertalanffy growth parameters, L sub( infinity ) (or W sub( infinity )) and K, and annual mean water ...
Small fishes as a resource in rural Bangladesh
Type: Journal Article
The role of small fishes in the diet of the rural poor in Bangladesh is described. Basic statistics (maximum size reached, length-weight relationships and prices) are presented for 42 species, belonging to 10 families and ...
The general von Bertalanffy growth function: possible use in the Beverton and Holt model
Type: Journal Article
Using the concept of generalized Von Bertalanffy growth formula developed by Pauly and Gasch? tz, we tried to integrate the basic equation of Beverton and Holt and to check on changes in the quantitative evaluation of ...
Variable number of tandem repeats in the mitochondrial DNA of Dascyllus trimaculatus
Type: Journal Article
The primary structure of the Dascyllus trimaculatus mitochondrial (mt) control region was determined, and conserved features were identified based on sequence comparisons to other teleostean fish species. Three ...
