Growth rings (GR) were counted in vertebrae of 69 female (56–221 cm precaudal length; 3–238 kg) and 54 male (57–216 cm; 3–180 C. leucas. Annual GR deposition could not be confirmed by centrum edge analyses but was assumed on the basis ‘mark–recapture’ analysis 10 sharks held captive for between 2.2 20 years an aquarium. counts indicated that largest 32 (221 cm) 29 (216 cm), respectively smallest mature 14 (197 25 (196 cm). Length at 50% maturity 193 (21 years) 190 (20 females males,...
Fisheries are recognized as important in Mozambique, yet they increasingly threatened by over-exploitation and climate change. We collate synthesize the available literature data on marine fisheries Mozambique; assess status of main fishery species/stocks; give an overview current management fishery, discuss planning for resilience face change predictions. In Mozambique there is a heavy reliance fisheries. From food security local economy perspective, critical sector artisanal which...
Marine species such as deep-sea geryonid crabs often exhibit high spatio-temporal variability in abundance and size over depth, substratum type season, therefore data collected from a single gear may not represent the whole population. Complementary trawl (soft substratum) trap (hard fisheries were analysed within general linear modelling (GLM) framework to assess distribution, population structure of Chaceon macphersoni off eastern South Africa. Catch rates, mean size, maturation sex ratio...
Abstract Shark catches are common in small‐scale (artisanal) and recreational fisheries; the magnitudes of these remain poorly known understudied, particularly developing countries. Data from three sources were used to assess composition shark landings fisheries Kenya: boat‐based fishery tagging 1987–2016; observed Bycatch Assessment Mitigation Western Indian Ocean Fisheries Project 2016–2017; Catch Surveys data 2017–2020. Eighteen species identified among 1,215 sharks recorded between June...
Abstract A survey of the recreational and commercial skiboat linefishery in Transkei was conducted from March 1997 to April 1999. Effort by skiboats substantially higher than skiboats, catch rates on boats were much boats. Catch region not greater those adjoining provinces KwaZulu-Natal Eastern Cape, but mean size fish caught southern larger that either or Cape. Total annual catches estimated for based returns submitted skippers National Marine Linefish System. Catches northern more diverse...
Abundance trends, population structure, and biology of the langoustine Metanephrops mozambicus (Macpherson, 1990) were investigated, based on commercial logbook information (1988-2010; 49 990 trawls) biological samples collected off eastern South Africa. A generalized linear model (GLM) framework was used to variation in catch rates, carapace length (CL), sex ratio, maturation size. Standardized rates inversely related fishing effort, gradually increasing between 2002 2010, when effort...
This study focuses on the KwaZulu-Natal deepwater crustacean trawl fishery located off east coast of South Africa. It investigates spatiotemporal changes in fishing effort and catch per unit three target species knife prawns (Haliporoides triarthrus), African langoustine (Metanephrops mozambicus) pink geryon (Chaceon macphersoni) using a space–time cube hotspot analysis ArcGIS Pro. shows contraction over time confining most productive localities to relatively small area directly vessels'...
Members of the rural communities living around edges Kosi Lake system in northern KwaZulu Natal have been subsistence users resources lakes, estuary and surrounding swamp forest for many generations. Women children dig up a variety crabs mangrove ecosystem, late 1980s collected as 638 000 year. The red crab Neosarmatium meinerti de Man, 1884 (Crustacea: Decapoda: Grapsidae: Sesarminae) constituted major proportion these catches, while Scylla serrata Cardisoma carnifex made rest. However,...
