Item type: Journal Article • Journal: African Journal of Marine Science • Authors: RJ Anderson C McKune JJ Bolton O Declerck E TronchinSubtidal seaweed communities of the northern coast of KwaZulu-Natal (KZN) have not been studied before. At Sodwana Bay, we tested the hypotheses that the seaweed communities would (1) differ floristically with depth, (2) be more species-rich in shallower water, (3)... -
A spatial- and age-structured assessment model to estimate the impact of illegal fishing and ecosystem change on the South African abalone Haliotis midae resource
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: ÉE Plagányi --- Department of Mathematics and Applied Mathematics, South Africa DS Butterworth --- Department of Mathematics and Applied Mathematics, South AfricaThe management of abalone stocks worldwide is complicated by factors such as illegal fishing combined with the difficulties of assessing a sedentary (but not immobile) resource that is often patchily distributed. The South African abalone Haliotis midae fishery is faced... -
Further refutation of the primary-secondary settlement hypothesis for the brown mussel Perna perna
