Abstract:
... In the last few decades, continuous attempts have been made to develop methods and technologies to increase fish production. However, unlike other research fields related to aquaculture, acoustic ranching of fish has never attracted intensive activity. Research and developments have been sporadic and lacking in international collaboration. In this review, we describe acoustic sea ranching studies ...

Abstract:
... Salmon sea lice represent one of the most important threats to salmon farming throughout the world. Results of private monitoring efforts have shown an increase in the number of positive cages and cage-level abundance of sea lice in southern Chile since 2004. As a consequence, the Chilean Fisheries Service implemented an Official Surveillance Program in the main salmon production area of southern ...

Abstract:
... Advances in salmon culture practices during the latter part of the 20th century provided the opportunity for mass production of juvenile salmon. Hatchery-produced salmon currently outnumber wild salmon in some regions around the Pacific Rim, raising concerns about their ecological impacts on wild salmon. We convened five regional sessions at an international conference to identify and discuss issu ...

Abstract:
... Although previous studies have suggested that rabbit excreta can be used as high-quality manure for sustaining plankton production due to their gradual nutrient release, integrated rabbit–fish production systems are still not widely used. Between 2006 and 2010 optimal rabbit densities for sustainable integrated rabbit–Nile tilapia farming were investigated at the Rwasave Fish Farming and Research ...

Abstract:
... Modern salmon hatcheries in Southeast Alaska were established in the 1970s when wild runs were at record low levels. Enhancement programs were designed to help rehabilitate depressed fisheries and to protect wild salmon stocks through detailed planning and permitting processes that included focused policies on genetics, pathology, and management. Hatcheries were located away from significant wild ...

Abstract:
... The ecological consequences of freshwater land-based salmonid farms on rivers were studied by monitoring eight farms with substantial differences in annual trout production (29–368tyear⁻¹) connected to rivers of contrasted hydrology (mean annual discharge ranging from 0.3 to 4.8m³s⁻¹) in France. Samples of water and benthic invertebrates were collected in the river immediately upstream and at two ...

Abstract:
... In Chile and Norway, countries with the highest salmon production in the world, salmons have developed chronic diseases due to toxicity problems from free metallic ions. Aluminum (Al) and iron (Fe) were found to be present in freshwaters used by the Chilean salmon industry. In this work, different alternatives for Al and Fe removal were compared to achieve the required standards in salmon culture. ...

Abstract:
... Year-round production of hybrid striped bass (female white bass Morone chrysops × male striped bass M. saxatilis) fingerlings would allow food fish growers to sell their product throughout the year, which would improve the consistency of market supply and cash flow for the farm. However, pond production of fingerlings is seasonal and precludes year-round supply. Tank culture methods have been deve ...
