Opis:: The current study explores the possibility that multiple fish farms (FFs) containing sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata) can be successfully integrated within a semi-enclosed bay in the Croatian Adriatic. The research focuses on determining principal environmental factors (EFs) that control the integration and attempts to estimate their individual and synergic ability to influence deposition and removal of organic matter (OM) and trace elements (TE) from the system. The complexity of the designated tasks demanded a comprehensive number of various datasets and samples to be used in the analysis. The ADCP data revealed strong wind induced currents forming within the research domain resulting in high system flushing efficiency (3.5—6 days). The sediment samples from all stations contained relatively inert minerals which contributed to overall low OM and TE concentrations and very limited variability found across the entire bathymetric range. The thermal advection effect recorded at two stations was attributed to specific seabed topography and the hydrodynamic response formed during Maestral wind episodes. The results indicate that a successful integra- tion of four FFs has taken place within the research site (semi enclosed bay), and that the key EFs responsible for its success are strong wind induced hydrodynamics, favorable seabed topography and sediment mineral composition. The synergy of the principal EFs that formed within the system was found to have an attenuating effect regarding FFs chemical influence (OM and TE) and an amplifying one regarding spatial footprint which extended to = 2000 m distance.

Tytuł:: Aquaculture for sustainable development in Nigeria

Opis:: Aquaculture is the rational rearing of fish and other aquatic organism in man-made ponds, reservoir and cages. It is also referred to as fish farming. Aquaculture is still being practiced at subsistence level in Nigeria. It is essentially a rural, secondary and part-time activity taking place in small farms in small freshwater ponds. Aquatic organisms produced through aquaculture include fish, aquatic invertebrates, planktons and aquatic plants (seaweeds). Aquaculture came as a solution to wild stock which are been depleted, to meet the protein need of the rural population and to overcome the problems inherent in wild fisheries. The application of aquaculture has unveiled to an extent the degree to which fish farming can sustain the economy and provide the necessary protein need of the country. The management of aquaculture for fish production starts from the setting up of the farm until the ponds begin to yield. The major management problem of fishery conservation is how to control both man and the aquatic crops for the present and the future when the demand will probably be greater than now. Aquaculture is very important and is the fastest growing animal based food producing sector particularly in developing countries.
