Ichthyoplankton off the Angola Continental Coast
2000
Afonso, M.H.
Results of the distribution and abundance of ichthyoplankton along the Angola Continental Coast are presented in this study. The first research survey of the NI "Capricornio" in the waters off Republica de Angola coast was carried on from 29 October to 3 December 1995. The study of the distribution, abundance and yield of the most important fisheries resources in the studied area were the main objectives of the cruise. The oceanographic characterization of the area and ichthyoplankton studies, were also undertaken. In order to study fish eggs and larvae, 37 oblique tows were made using a plankton Bongo net, to a maximum depth of 200 m. Larvae of 47 taxa were taken during the investigation. Thirty five of those taxa were identified to family, 8 to genus and 4 to species level. Myctophidae was the dominant family representing 46,4% of the total amount of collected fish larvae. Seven families of commercial interest were identified in the catches with the following percentages of occurrence: Clupeidae (15,4%), Sparidae (9,1%) Scombridae (4,4%), Carangidae (3,7%), Soleidae (0,5%), Bothidae (0,2%) and Serranidae (0,08%). No correlation was found between the number of fish larvae and the zooplanktonic biomass
