Title: Utilization of Mangrove Wetlands as Nursery for Fishes of Ecological and Commercial Importance in Ghana

Abstract:

Mangrove ecosystems are tropical and subtropical coastal wetlands that provide a vast range of ecological and socioeconomic services. In Ghana, mangrove wetlands are found fringing several estuaries and lagoons along the entire coastline of approximately 550 km long. Ecologically, the functions of these coastal wetlands include water purification, flood and drought control of adjoining ecosystems, nutrient cycling and distribution, and the provision of feeding and nursery grounds to fish assemblages. This paper chronicles, trends in fish densities, diversity and distribution in mangrove wetlands, and the nature of utilization with respect to prevailing environmental conditions in mangrove wetlands in Ghana, West Africa. Investigations focused on the stature of fish assemblages in mangrove wetlands and other associated coastal water bodies in relation to hydrographic and hydrodynamic conditions. Findings of these studies established that fish community structure of coastal wetlands are spatially and temporally homologous to dynamics in physicochemical factors, hydrological, hydrographic and hydrodynamic conditions. Several species of fin- and shellfishes of both ecological and commercial importance are found to utilize mangrove wetlands for the purpose of nursery and evasion of predation with up to 98% of the abundance encountered in these habitats classified as juveniles. Species diversity and richness suggest that most of the fishes found in mangrove wetlands are of marine origin including species of Mugilidae, Clupeidae, Carangidae, Portunidae, Penaedae with species of Cichlidae and Gobiidae as the predominant brackishwater species. With capture fisheries of Ghana experiencing a continuous decline in recent times, the observations made through these studies with respect to the role of mangrove wetlands in fish recruitment cannot be over-emphasized.
