A spatio-temporal assessment of the Trachinotus botla shore-fishery in KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: D Parker --- Department of Ichthyology and Fisheries Science, South Africa AJ Booth --- Department of Ichthyology and Fisheries Science, South Africa BQ Mann --- , South AfricaThe shore-fishery for Trachinotus botla in KwaZulu-Natal appears to be in a stable state. A per-recruit assessment showed that the species is currently underexploited (spawner biomass-per-recruit = 75% of pristine levels) and that fishing mortality could theoretically be increased. The... -
Using baseline biological and ecological information to design a Traffic Light Precautionary Management Framework for leerfish Lichia amia (Linnaeus 1758) in southern Angola
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: WM Potts WHH Sauer A-R Childs ADC DuarteThe coastline of southern Angola is sparsely populated and, largely because of a protracted civil war, has very lightly exploited inshore fish stocks. This has provided the almost unprecedented opportunity to determine prefishing-state reference points and to implement management strategies... -
Quantifying the largest aggregation of giant trevally Caranx ignobilis (Carangidae) on record: implications for management
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: R Daly --- Port Elizabeth Museum at Bayworld, South Africa CAK Daly --- Save Our Seas Foundation (SOSF) D’Arros Research Centre, Switzerland RH Bennett --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa PD Cowley --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa MAM Pereira --- Centro Terra Viva, Mozambique JD Filmalter --- South African Institute for Aquatic Biodiversity (SAIAB), South AfricaThe giant trevally Caranx ignobilis (Forsskål) is an important apex predatory fish typically associated with coral reef communities. It is prized in recreational and commercial fisheries, yet little is known about its aggregation dynamics and susceptibility to fishing pressure. This... -
The movements of adult leerfish Lichia amia in the Breede Estuary, Western Cape, South Africa: insights from acoustic telemetry
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: WM Kilian --- Rhodes University, South Africa TS Murray --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa JD Filmalter --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa PD Cowley --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa TF Næsje --- South African Institute for Aquatic Biodiversity (SAIAB), South Africa RJ Wasserman --- Rhodes University, South AfricaLeerfish Lichia amia inhabit estuaries as juveniles before moving between estuaries and the marine environment as sub-adults and adults. While adults remain mostly in the marine environment, philopatry has been observed, with individuals returning to areas previously used, including estuaries...
