A comprehensive survey on selective breeding programs and seed market in the European aquaculture fish industry

Abstract

The use of selective breeding is still relatively limited in aquaculture species. Information on such activities is sparse, hindering an overall evaluation of their success. Here, we report on the results of an online survey of the major aquaculture breeding companies operating in Europe. Six main reared fish species were targeted. A total of 31 respondents contributed to the survey, representing 75 % of European breeding organizations. Family-based breeding schemes were predominant, but individual selection was more frequently applied in marine species. Artificial fertilization is the preferred means of reproduction; however, mass spawning is often used as a fallback method. The most frequently selected trait is growth performance, but the number of selected traits has been increasing over the years through the addition of traits such as disease resistance or product quality. The use of molecular tools is now common in all programs, mainly for pedigree traceability. An increasing number of programs use either genomic or marker-assisted selection. Results related to the seed production market confirmed that for Atlantic salmon there are a few dominant players at the European level, with 30-50 % market share. Only part of the European fish aquaculture industry today fully exploits selective breeding to the best advantage. A larger impact assessment still needs to be made by the remainder, particularly on the market share of fish seed (eggs, larvae or juveniles) and its consequences for hatchery stability

Predicting shifting sustainability trade‐offs in marine finfish aquaculture under climate change

“…Therefore, present approach can provide a sound environmental baseline for constructing integrated models which allows one to explore socioeconomic future scenarios of (a) the industry development, (b) the markets’ prices adaptive replies to the climate change, and (c) the growing seafood proteins demands. This will allow to build proactive models for a sustainable aquaculture (Chavanne et al., ; Sarà, Mangano et al., ).…”

Applications of genotyping by sequencing in aquaculture breeding and genetics

“…Aquaculture breeding schemes tend to lag behind their terrestrial livestock counterparts in terms of the uptake of genomic technologies, and for many aquaculture species, molecular genetic tools are only applied for pedigree reconstruction (Chavanne et al . ). In comparison, most modern breeding programmes in livestock are now underpinned by genomic selection (GS, Meuwissen et al .…”

A systematic quantitative literature review of aquaculture genetic resource access and benefit sharing

“…In contrast to the agriculture sector, aquaculture has a high percentage of production from wild‐derived seed, or closely related to wild stocks, and a much smaller proportion of genetically improved material (Gjedrem ; Chavanne et al . ). Most of the genetically improved stocks in aquaculture are derived from selective breeding programmes rather than biotechnology interventions (Gjedrem ).…”
