Early Sturgeon Sex Discrimination (ESSD), a new diagnostic service for hatcheries and farms
This article was featured in EUROFISH Magazine 2 2021.
Sturgeon farmers producing fish for caviar would benefit hugely from a molecular-biological sex test for juvenile and adolescent sturgeons. Early sexual identification can significantly decrease production costs by increasing the number of females for caviar production while maintaining a balance of male animals for meat production and for use as brood stock.
Additional advantages from the genomic analysis to determine sex could be the identification of genes implicated in growth, meat production, or egg quality (caviar) which opens the door for improvements in these areas. Currently, the normal male to female ratio in production facilities is approximately 1:1 through natural selection. If an early sex test is available, then this ratio could be manipulated to favour the production of either caviar or meat.
Between 13-14 November 2018, the Food and Agriculture Organization of the United Nations (FAO) and International Organization for the Development of Fisheries and Aquaculture in Europe (EUROFISH), in cooperation with the European Inland Fisheries and Aquaculture Advisory Commission (EIFAAC), the Romanian Ministry of Agriculture and Rural Development, the Romanian Ministry of Waters and Forests, the Danube Sturgeon Task Force and the International Association for Danube Research, organize in Bucharest a Regional Conference on river habitat restoration in the Danube Basin and Black Sea area.
The aim of this conference is to contribute to the revival of fish populations, inland and recreational fisheries, food security, and livelihoods of riparian communities. A particular focus will be placed on sturgeons as the flagship species of the Danube River Basin, long distance migratory species currently under recovery, but who still require special protection measures against illegal fishery. To support sturgeon recovery in the Danube River, Romania, through the Ministry of Agriculture and Rural Development and the Ministry of Environment, Waters and Forests, restricted the commercial fishery of these valuable species since 2006 for a period of 15 years. The conservation of Danube sturgeons is supported by the European Commission, the EU Strategy for the Danube Region and numerous Danube stakeholders implementing the program Sturgeon 2020.
This conference marks the beginning of a closer dialogue between the environmental and fishery/aquaculture authorities from the Danube countries, aiming to reduce the current decline of freshwater fish species and identify constructive solutions for the revival of endangered species and fish populations with high economic value, bringing benefits to the riverine communities along the Danube River. With this occasion, besides discussing urgent measures that need to be implemented, successful examples and good practices applied in other European states will be presented to foster their adaptation at regional level.
Fishery and aquaculture provide valuable food and income resources for approximately 820 million people worldwide, starting with recreational and commercial fishery, and ending with processing, marketing and distribution of different fish products. For many communities, they represent part of the local tradition and cultural identity.
