Optimisation of rearing conditions in sea bass for eliminated lordosis and improved musculoskeletal growth *

Contract nr: QLRT-CT-2000-01233
Project type: RS (Research and Technological Development Project)
Starting date:
Duration: 36 months
Total cost: 1,219,727 EUR
EC Contribution: 1,023,000 EUR
Scientific Officer:
Research topic: 5.1.2. Sustainable fisheries and aquaculture

Abstract:
The objectives of this project are:

a. to identify the critical environmental (temperature and current speeds) and nutritional (mainly Vitamins C and E and Selenium) factors which predispose fish to lordosis;
b. to understand the influence of these factors on musculoskeletal development and integrity and their relationship with lordosis; and
c. to provide a tool for standardised assessment of quality in a commercial environment. These objectives will be achieved through an integrated, multidisciplinary approach involving aquaculture specialists and musculoskeletal biologists who will assess sea bass larvae and juveniles reared under different environmental and nutritional conditions. Results will help to understand the reasons for lordosis and will indicate optimum conditions for its elimination.

Objectives:
Lordosis and other vertebral deformities are significant problems in European marine aquaculture including sea bass. These problems have a serious impact on the industry' s productivity, on product quality and on animal welfare. The objectves are:

1. to assess the influence of rearing temperature, nutrition (mainly Vitamins C and E and Selenium), current velocities and their interactions on the incidence of lordosis;
2. to assess, for the same factors and same groups of fish, the influence on musculoskeletal development and growth at tissue, cell protein and molecular level, as an informed basis for reducing the problem of lordosis and for optimising musculoskeletal growth; and
3. to provide a tool for standardised assessment of quality in a commercial environment, which will take into account not only the presence or absence of skeletal deformities, but also the real effects of their different expression intensities on both biological performance and product final image. These objectives will help to achieve the aims of improving aquatic production and the competitiveness of the European aquatic industry. These aims are directly relevant to the Quality of Life programme, specifically Action 5.1.2.
