Item type: Journal Article • Journal: African Journal of Marine Science • Authors: A. M. P. Van Schie W. F. De BoerThe population dynamics of flatfish Solea bleekeri and Pseudorhombus arsius within the intertidal area of Inhaca Island, Moçambique, was investigated using bottom trawl data collected during summer (December 1996 – March 1997) and winter (June 1997 – August 1997). The... -
Spatial and seasonal patterns in sighting rate and life-history composition of the white shark Carcharodon carcharias at Mossel Bay, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: R Ryklief --- Department of Zoology, South Africa PA Pistorius --- Department of Zoology, South Africa R Johnson --- Oceans Research, South AfricaWhite sharks Carcharodon carcharias aggregate at specific times of the year at localities along the South African coast. At Mossel Bay, on the southern Cape coast, four sites were sampled (Seal Island, Hartenbos, Kleinbrak and Grootbrak) to investigate spatial and... -
Preliminary examination of hatching season and growth of Engraulicypris sardella (Pisces: Cyprinidae) larvae and juveniles in Lake Malawi
Item type: Journal Article • Journal: African Zoology • Authors: Shinsuke Morioka --- Department of Aquaculture and Fisheries Science, Bunda College of Agriculture, Malawi Emmanuel Kaunda --- Department of Aquaculture and Fisheries Science, Bunda College of Agriculture, MalawiThe hatching period and the growth of Malawian cyprinid Engraulicypris sardella larvae and juveniles collected from two sites along the southwestern shoreline of Lake Malawi were investigated using otolith increment information. The lapillus was used to determine the age in... -
Spatio-temporal patterns of coral recruitment at Vamizi Island, Quirimbas Archipelago, Mozambique
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: E Sola --- School of Life Sciences, South Africa I Marques da Silva --- Faculdade de Ciências Naturais, Moçambique D Glassom --- School of Life Sciences, South AfricaSpatial and temporal patterns of recruitment of reef corals were assessed for the first time in Mozambique by deploying settlement plates at various spatio-temporal scales between October 2012 and October 2013. The abundance of juvenile corals (5−50 mm in diameter) was... -
Bull shark Carcharhinus leucas recruitment into the St Lucia Estuary, South Africa, after prolonged mouth closure, and the first observation of a neonate bull shark preyed on by a Nile crocodile Crocodylus niloticus
