Lanternfish heaven: the future of world fisheries?
Type: Journal Article
The differences between fishes in their size, behavior and food make them more or less vulnerable to fishing pressure. Large predators, long-lived fish, most trawl species and pelagic schooling fishes will possibly become ...
Fishermen's knowledge as background information in tropical fish ecology: a quantitative comparison with fish sampling results
Type: Journal Article
An investigation of fishermen€™s knowledge of fish occurrence patterns on various spatio-temporal scales has been realized in the Fatala Estuary (Guinea, West Africa), accompanied by a one-year survey with standardized ...
Length-weight relationships of five species of the family Sparidae in the Gulf of Guinea
Type: Journal Article
Length-weight relationships are presented by sex and by country for five species of the family Sparidae (Pugrus caeruleostictus, Pagellus bellottii, Dentex canariensis, Dentex congonensis, Dentex angolensis) sampled in ...
Integrated management of coastal fisheries: lessons from initiatives in San Miguel Bay, Philippines
Type: Conference Proceedings
Coastal fisheries occur in a variety of natural and human settings. In terms of coastal use intensity, fisheries may be viewed to operate in a spectrum ranging from essentially single sector (i.e., fisheries) situations ...
Biology, fisheries and culture of tropical groupers and snappers
Type: Conference Proceedings
Groupers and snappers are important fishery resources of the tropics and subtropics, where their high values have caused most of their stocks to be heavily exploited, some even to the point of collapse. Trends towards heavy ...
Outmigration and movement of tagged coral reef fish in a marine fishery reserve in Jamaica
Type: Book Chapter
Between December, 1996 and May, 1998, a total of 6,947 coral reef fish were marked and released within the Discovery Bay Fishery Reserve, on the north coast of Jamaica. Nearly 6,000 recaptures have been obtained (including ...
Assessment of Lutjanus vivanus and Lutjanus buccanella in the north Caribbean coast of Costa Rica
Type: Journal Article
This paper presents results of stock assessment on two snapper species, Lutjanus vivanus and L. buccanella, in the north Caribbean coast of Costa Rica. Growth parameters, mortality rates, length-weight relationships, ...
Developments in tropical reef fisheries science and management
Type: Book Chapter
Extinction is conceivable for some species, including aquarium-fish stocks of high value and limited geographical range, but a biological basis exists for management of such small fishes. Immediate data needs are much ...
Can we use traditional length-based fish stock assessment when growth is seasonal?
Type: Journal Article
Based on simulated catch data, this contribution shows that standard length-converted catch curves cannot be used for accurately estimating total mortality when growth oscillates seasonally. Some implications for length-based ...
VPA estimates of fishing mortality and exploited biomass from Sardinella aurita catch-at-length data in eastern Venezuela
Type: Journal Article
In this study, length-frequency data on Spanish sardine (Sardinella aurita) from northeastern Venezuela were analyzed for the period 1967-1989. Average growth parameters for the von Bertalanffy equation were established ...
