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.

A Danish company has developed a system based on analysing data collected from 12 locations on a fish farm to improve water quality and fish welfare while reducing costs. Blue Unit, a company founded by David Owen, a biologist, in 2009, was established to optimise the operations of recirculation aquaculture systems by exploiting the data available from the RAS. A centralised monitoring system collects data on 13 water quality parameters, including pH, oxygen and carbon dioxide levels, opacity, and salinity, that are monitored by specially designed sensors and compares the numbers with benchmark values from producers around the world.

A new book from the Turkish Marine Research Foundation celebrates the country’s aquaculture industry, the third largest by volume in Europe after Norway and Spain. The book, Marine Aquaculture in Turkey: Advancements and Management, is a collection of papers written by academics, resource managers, and representatives from industry. Edited by M. Didem Demircan and Deniz D. Tosun from Istanbul University, and Deniz Coban from Aydin Adnan Menderes University, the papers cover all aspects of the aquaculture industry from production to the sector’s effects on the environment and on occupational health. Production Is fully integrated starting from broodstock and ending in a range of products for the market. Seabass, seabream, and rainbow trout farmed inland are the most cultivated species, but smaller volumes of several other species are also produced.

The sector boasts 20 hatcheries, 23 feed plants, and over 200 processing facilities, and it maintains close links with the research establishment based in universities and institutes as well as with the government. Turkish legislation is harmonised with EU directives and regulations enabling the country to export some four fifths of its production to the EU. In 2023 the target is to produce 600,000 tonnes (up from 373,000 tonnes in 2019) and to export USD2bn (up from USD1bn in 2019) worth of fish and seafood products.

Seafood consumption on the increase

Ukraine celebrates its 30th anniversary of independence this year. As a young and developing country it is still implementing the reforms designed to build a modern and efficient state. Initial efforts catalysed the signing of the Ukraine–European Union Association Agreement in 2014, which entered into force in 2017 and which, when fully ratified, offers Ukraine duty-free access to the EU market, political and financial support, and access to EU research and other programmes. In return, Ukraine shall continue more firmly on its path of reform particularly in the legislative and judicial area, economic regulation, and finance.

A versatile and robust mechanical feeder

A German company, FIAP offers a range of equipment for the aquaculture sector from sophisticated recirculation systems to hand-held nets.

An aquaculture farm whether on land or at sea is a rough environment and the equipment used needs to be tough and reliable if the farm is to operate successfully. FIAP’s Profifeed BeltFeeder is a mechanically driven automatic feeder that can be used in the most demanding environments to deliver feed or other inputs, such as medicines or additives, to the water. The material can take any form from dust to large pellets. The feeder is started manually and can be set to run for 4, 12, or 24 hours during which time it will steadily dispense the medium enabling extremely ef- ficient workflows.

On a global scale European production of algae is very modest, but companies and research bodies find that algae can contribute to addressing important issues faced in Europe including sustainability, human and animal health, and plastic pollution. The positive role algae can play in these and other fields were among the topics discussed at the AlgaEurope conference.

The AlgaEurope conference is an annual event that brings together industry and academia involved in algae research, cultivation, and application to discuss the further development of the sector in Europe and beyond. The forum provides companies, established academics, budding scientists, and regional, national, and European policy-makers with an opportunity to network while exchanging knowledge and experience about algae. The conference is organised by the European Algae Biomass Association and DLG Benelux, part of the German Agriculture Society, DLG.
