The aim of this study was to investigate the effects fish cage culture on Macrobenthic in southern Caspian Sea. Samples were collected two offshore farms with four floating polyethylene cages a production 60 tons for 5 months 2015. Sampling performed macrobenthos, physicochemical, and sediment January, March, May, August at depths shade, 50, 100, 1000 m three geographical directions (east, west...

We determined the optimum dietary protein level in juvenile barred knifejaw Oplegnathus fasciatus in cages. Five semi-purified isocaloric diets were formulated with white fish meal and casein-based diets to contain 35, 40, 45, 50, and 60 % crude protein (CP). Fish with an initial body weight of 7.1 ± 0.06 g (mean ± SD) were randomly distributed into 15 net cages (each size: 60 cm × 40 cm × 90 c...

This study aims to determine the profile of dissolved oxygen and H2S based on depth in Jatiluhur Reservoir related fish culture floating net cages. The scope this research is focused location cage cultivation. Dissolved distribution classified as a positive heterograde type where levels higher metalimnion layer due photosynthesis process that occurs effectively by aquatic plants phytoplankton. ...

Impact of Atlantic salmon (Salmo salar) cage culture in Mjoifjordur, Eastern Iceland on the chemistry of the sediment was investigated. Sediment samples were collected using a Shipek grab in December 2003. A core sub-sample was taken from each grab for analyzing total organic matter, total organic carbon, total nitrogen and phosphorus in different depths from three stations at various distances...

Over the last 2 decades marine open cage aquaculture in the Mediterranean Sea has grown rapidly, leading to increased productivity in the water column near fish farms. Here we investigated the effect of such increase in productivity on the common bottlenose dolphin Tursiops truncatus. We developed an ecosystem model for the inner Ionian Sea Archipelago, western Greece, to: (1) evaluate the trop...

Philip Lymbery is an international animal welfare consultant. In 1992, his report, The Welfare of Farmed Fish, was the UK's first to look at the welfare issues in salmon and trout farming. This was written whilst working for Compassion In World Farming (1990-2000), where he spent the last 7 years as Campaigns Director. Maintaining a special interest in fish welfare, Philip submitted both writte...

Aquaculture is growing rapidly around the world. In Brazil, fish farming in net tanks has high potential due its large number of reservoirs. However, cultivable areas with a density may be more susceptible to eutrophication compared other production systems, and impair ecosystem where they are installed. Therefore, attention needed this type system avoid environmental impacts. The objective stu...
