Optimisation of the rearing technology for blackspot seabream (pagellus bogaraveo)

To develop a rearing technology for blackspot seabream transferable to the industrial sector. Optimisation of the preliminary results will enable the development of a new species for european aquaculture.

The aim of this project is the development of a blackspot sea bream rearing technology, transferable to the industry, to allow for the introduction of a new species blackspot to European aquaculture. To do this, it is necessary to improve the results of the previous limited research, optimising some of the critical issues that are key to transferring the technology to companies, and to develop a sustainable and viable activity. The strategy to include this new aquaculture species in its range of products will allow the company, besides widening its offer and diversifying its risks, to maintain a competitive advantage with respect to its direct competitors, being the only provider of farmed blackspot in the market for the coming years. The research will focus on four key bottlenecks hindering the scale up of blackspot farming to industrial levels: 1. Development of a larval rearing technique that supports a stable and reliable production of good quality blackspot fry. The objective is to standardise a protocol to provide a good larval survival, over 15%, and a percentage of fish under the market standard below 10%. 2. Development of a juvenile production technique at a reasonable cost, allowing for economic feasibility throughout the ongrowing stage. The objective is to reach a fry cost similar to turbot (around 1 euro/fish). 3. Development of a production management system in cages and the formulation of a specific diet for blackspot, to maximise the growth curve, thus shortening the production cycle. The objective is to reduce the ongrowing phase to 36 months in cages in order to reach the commercial size of 500g. 4. Development of a feeding management strategy to allow for the reduction of the feed conversion rate. The objective is to come to a final FCR (Feed Conversion Ratio) below 3. Once the developed technology is transferred to the industrial sector, a new aquaculture product will be available in the European fish market. In addition to increasing the offer of farmed marine fish species, it will help to maintain price stability thus making blackspot more affordable for a bigger number of families, instead of being restricted to groups with higher purchasing power.
