SILVER EEL - (QLRT-1999-31141)
In recent decades, a substantial decrease in the European eel (Anguilla anguilla) population has been observed in Europe. The concern is that this might also reflect the situation with silver eels. What is known is that silver eel populations in Europe's rivers are being affected by commercial fishing and deaths are also resulting from eels ... More (full abstract).
Aquaculture and coastal economy and social sustainability
AQCESS - (QLRT-1999-31151)
Fishing and aquaculture are important economic activities in the European Union. This project offers a holistic and innovative approach to the questions of social, economic, environmental and ecological sustainability posed by the development of aquaculture and the changing fishery exploitation in coastal areas. It also integrates multi-disciplinary ... More (full abstract).

Improving production efficiency of sea bass farming by developing methodologies to eliminate environmental androgenesis
PROBASS - (QLRT-1999-31365)
The purpose of the PROBASS project is to address the problem faced by the sea bass aquaculture, which is that under culture conditions most of the fish (70-99%) are males. In addition, males grow slower than females and weigh up to 40% less at harvest, which reduces their market value, or they need to be cultured for longer, which increases production ...

Reducing the conflict between cormorants and fisheries on a pan-European scale
REDCAFE - (QLRT-1999-31387)
The purpose of REDCAFE is to synthesise current cormorant and fishery information, and to identify and evaluate methods of reducing the current Europe-wide conflict between conservationists and fisheries' interests. It will bring together, for the first time, stakeholders (commercial/recreational fisheries, bird conservation organisations, fishery ... More (full abstract).

Improved procedures for flatfish larval rearing through the use of probiotic bacteria
PROBE - (QLRT-1999-31457)
Six partners will pursue a new, coordinated and systematic approach to improve the rearing of larval turbot using biological, non-antibiotic-dependent measures of disease control. Four different approaches will be applied to select probiotic bacteria (those that prevent the harmful effects of disease-causing microorganisms) from a large number of isolates ...

Regulations of skin colouration in the Red Porgy (Pagrus pagrus): Towards the development of natural hue in cultured populations
COLORED - (QLRT-1999-31629)
The red porgy is one of the most popular sparids in the Mediterranean region and along the Atlantic coast, and initial commercial trials have already been performed in several Mediterranean fish farms. The purpose of this project is to resolve the main problem for moving towards commercial production, which is the discoloration of skin observed in ... More (full abstract).
Gastrointestinal functions and food intake regulation in salmonids: Impact of dietary vegetable lipids
GUTINTEGRITY - (QLRT-1999-31656)
Sustainable and ethical aquaculture is of future economic importance for the many rural areas of the European Union. To achieve this, the industry needs to lessen its dependence on fish meal and oil as a basis for fish feed. Vegetable lipids may be a major source of alternative energy for cultured fish, but current knowledge of their effects on the ... More (full abstract).
