Opening Paragraph

Opening ParagraphThe Aŋlo are an Ewe-speaking people who occupy the low-lying coastal area between the Volta river in Ghana and Lome, the capital of Togo. They are among the most mobile of West African peoples, Aŋlo beach seine fishing companies having for many years operated from beaches as far afield as Sierra Leone and Angola. In recent years, however, the governments of certain West African countries have ordered their removal in attempts to protect the interests of indigenous fishermen. This has meant that these companies have tended more and more to return to Ghanaian beaches, but have found that the increasing mechanization of Ghanaian coastal fishing presents a serious threat to their continued operation.

Abundance And Diversity

Abstract In the present work, spatial and seasonal fluctuations of the abundance and diversity of mesozooplankton are presented, with special attention being given to copepod assemblages from coastal area of the Fernando de Noronha Archipelago (FNA) (3°50'24''S and 32°24'48''W). Sampling was carried out during the dry and rainy seasons of two consecutive years (July and December 2013) and (June and November 2014). A total of 37 mesozooplankton taxa were recorded, being the copepods the most diversified group (15 taxa). The Subclass Copepoda dominated in both periods sampled, comprising 53% and 86% of the total abundance in the dry and rainy season respectively. The species considered abundant were: Calanopia americana, Undinula vulgaris, Oithona plumifera and Corycaeus speciosus. The rainy season favored a significant increase in the abundance of mesozooplankton and copepods. However, a low value of the Shannon-Wiener diversity index was observed in this same seasonal period. This was explained by the dominance of the species C. americana and U. vulgaris in the studied area. Spatial differences have not been verified. The copepod assemblages was composed mostly by species considered as predator-carnivours of greater importance on the pelagic trophic web, indicators of oligotrophic conditions and components of a major portion of fish food items. Thus, we suggest that a spatially homogeneous mesozooplankton community characterizes the coastal area of Fernando de Noronha Archipelago with variations related mainly to the seasonal factor.
