Length-weight relationships of marine fishes from the central Brazilian coast
Type: Journal Article
Parameters of the length-weight relationship are presented for 85 fish species from the marine and estuarine regions of the central Brazilian coast (latitude 13° to 23° S). Three different methods were used. A non-linear ...
Relative Importance of Various Predators in Clarias gariepinus Fry Mortality in Cameroon
Type: Journal Article
To estimate the relative importance of the most common predators of Clarias gariepinus fry, increasing levels of protection were afforded to exclude amphibians, aquatic arthropods and birds. At a stocking density of 10 ...
Stock improvement of silver barb (Barbodes gonionotus Bleeker) through several generations of genetic selection
Type: Journal Article
This paper reports stock improvement of silver barb (Barbodes gonionotus Bleeker) using selective breeding techniques and presents the results of three generations of growth performance between selected and nonselected ...
An empirical bio-economic stocking model for floodplain beels in Bangladesh.
Type: Journal Article
While stocking floodplain depressions or beels with fingerlings is a common form of fisheries management in Bangladesh, bio-economic guidance for improving the outcome of stocking strategies is sparse. The Community-Based ...
A new era for restocking, stock enhancement and sea ranching of coastal fisheries resources
Type: Journal Article
The growing number of countries investigating the potential for releasing cultured juveniles to augment coastal fisheries resulted in the First International Symposium on Stock Enhancement and Sea Ranching (ISSESR) in ...
A simple spreadsheet model to incorporate seasonal growth into length-based stock assessment methods
Type: Journal Article
The paper describes a method by which seasonal growth can be incorporated into length-converted catch curves and cohort analyses using a spreadsheet. The method is based on calculating the length of fish using seasonal ...
Reducing the costs of restocking giant clams in Solomon Islands
Type: Journal Article
On many corals reefs in the Indo-Pacific, the larger species of giant clams (Tridacnidae) have either been eliminated or fished down to the point where the external fertilization of gametes is improbable. In the mid 1980s, ...
Towards the maximum profitability of smallholder catfish nurseries: predator defense and feeding-adapted stocking of Clarias gariepinus
Type: Journal Article
To determine how best smallholders could maximize the profitability of their catfish hatcheries, the cost/benefit analyses of using fences, hapas and bird nets to exclude predators; as well as over-stocking to create food ...
Evaluating mortality using length-frequency data when growth parameters are poorly known
Type: Journal Article
A method is presented through which the total mortality undergone by several fish stocks of the same species can be compared when growth parameters are poorly known or unknown. Whereas the estimate of Z obtained via the ...
Exploitation of the dolphin-fish Coryphaena hippurus L. off Ecuador: analysis by length-based virtual population analysis
Type: Journal Article
Dolphin-fish Coryphaena hippurus in the east Central Pacific are principally exploited by Ecuador. A length-based virtual population analysis of this fishery was sensitive to assumed values of growth parameters in ...
