Project

Optimal smolt production and post smolt performance in the High North - Seawater intermixing, low temperatures and intensive rearing

Facts

Start 1. April 2008
End 31. March 2011
Funded by The Research Council of Norway - HAVBRUK

This project proposal intends to investigate various aspects of production strategies of Atlantic salmon (Salmo salar L.) smolt in Northern-Norway. Production strategies that can make this region self-sufficient with smolts, and contribute to improved survival, growth, health, and low risk of winter ulcer outbreaks in farmed salmon, both during hatchery and sea cage stages.

Focus

The main focus will be the effect on both juvenile salmon and smolts of exposure to different salinities, temperature regimes and production intensity on performance measured as growth, immune competence and disease resistance, and various aspects of physiology.

Evaluation of performance will include the parr and smolt stage, as well as subsequent sea performance, thus integrating effects over relevant production stages. The project will determine safe levels of the various parameters (salinity, temperature and production intensity) at the parr and smolt stage, and initiate development of a production model based on limitations and optimal combinations of parameters obtained from experimental studies in this and previous projects.

Implications

The proposed project will benefit the industry by providing scientific based information on the effects of currently applied production strategies, as well as recommendations to optimize fish performance and welfare to obtain a self-sufficient salmon industry in the northern region.
