Advantages and risks of land-based fish production

This article was featured in Eurofish Magazine 5 2021

Until now, recirculating aquaculture systems (RAS) have mostly been used to produce freshwater fish species such as eel, African catfish, tilapia, zander or sturgeon. Now, however, an increasing number of projects for land-based RAS that are designed for marine fish are emerging. For salmon alone, the planned capacity is over half a million tonnes. Investors are fuelling this development, but are their profit expectations actually justified?

Eurofish Magazine issue 5 2021 looks at the fisheries sector in Romania and whether recirculating aquaculture systems is the future of mariculture? The trade and markets section features an article on how the transport and logistics sector is undergoing a global
transformation protecting the environment and the climate.

Carp production in semi-intensive conditions can very significantly

This article was featured in Eurofish Magazine 4 2021.

Cereal grains, pelleted, and extruded feed in semi-intensive common carp production have different impacts on production, meat quality, the pond ecosystem, and profitability.

Common carp (Cyprinus carpio L.) is one of the most important species of farmed fish. It is farmed in more than a hundred countries of the world, mainly in earthen ponds. Most of the production is in semi-intensive culture systems. Such production is based on boosted natural food produced in the pond with supplemental feed. Although simple at first appearance, this farming method has a whole range of options: from traditional farming methods based on feeding with cereal grains and other locally available plants to production based on the use of high quality compound feeds. In Europe semi-intensive production based on feeding with cereal grains is still dominant. Although in some countries, such as Serbia, cereals have been largely replaced by compound (extruded) feeds.

Quantities produced reached a record level in 2019

This article was featured in EUROFISH Magazine 4/2021.

According to surveys carried out by the Food and Agriculture Organisation (FAO), the quantities produced by global aquaculture reached an all-time high of 120 million tonnes (live weight) in the year 2019, with a total sale value (ex farm gate) of 274.6 billion US dollars. Of this, 85.3 million tonnes were accounted for by animals (USD 259.5 billion), 34.7 million tonnes by algae and aquatic plants (USD 14.8 billion) and 26,841 tonnes by ornamental shellfish and pearls (USD 228.4 million).

The quantities produced by global aquaculture have been increasing for decades and have become enormously important for feeding the world’s population. An example of this development is the proportion of the global fish supply made up by aquaculture, which was 47.9 percent in 2019. This means that almost half of all fish consumed glob- ally that year came from a farm. At the turn of the millennium, this proportion was only about a quarter (25.7 percent). The point at which more fish will come from aquaculture than from fisheries is not so far away. In some production areas, the ‘more farmed than caught’ milestone has actually already been reached. In the year 1970, the quantity of algae and water plants produced by aquaculture exceeded the amount from natural harvesting for the first time. In 1986, this milestone was reached for freshwater fish, and in 1994 for molluscs. In 1997, it was the turn of diadromous fish species, which include sturgeon and some salmonid species that regularly migrate between salt and fresh waters during specific life cycles, and in 2014 more crustaceans were farmed than were caught in the wild for the first time.

Eurofish Magazine issue 4 2021 looks at the fisheries sector in Itlay and how the fishing fleets adapt to the pandemic. Consumption in Croatia is also reviewed as well as carp farming in Serbia.  The species profile looks at Musky octopus (Eledone moschata).

Recognising women’s essential, but often unacknowledged, roles in Spanish fishing and aquaculture

This article was featured in Eurofish Magazine 3 2021.

Fishing is more than taking fish from the ocean or from inland lakes and streams. The simplistic image of men labouring on the sea in the face of nature’s harsh challenges does not portray the complexities of today’s fishing sector. Before and after fish are taken, a large amount of work must be done, on board and ashore, by both men and women.

Sustainability certificates increase trust in aquaculture products

This article was featured in Eurofish Magazine 3 2021.

In many European countries it is currently a somewhat rare find. In other regions of the world, however, the blue and white Best Aquaculture Practices logo with its three stylised fish is much more widespread and is recognised as a symbol of socially responsible, sustainable and environmentally friendly fish and seafood products. What does the BAP seal stand for, has it earned the trust of consumers and should we be paying more attention to it?

Biomark provides advanced technology solutions for broodstock management

This article was featured in Eurofish Magazine 3/2021.

Broodstock management lies at the heart of successful aquaculture production. Fish that better meet market demand are produced through generations of strategic breeding. Regardless of species or location, monitoring broodstock success requires careful analysis of breeding efforts and the ability to trace offspring.

RFID technology or PIT tag implantation is a popular solution for broodstock management. The ability to track individuals throughout their lifecycle is an effective strategy for observing the heritability of traits related to survival, growth, disease resistance, fecundity, etc. By incorporating genetic data with RFID tracking, managers can identify target genotypes associated with desirable traits, and then optimise breeding strategies to ensure the expression of those desirable traits in the hatchery population. The use of PIT tag unique identifiers is critical to separating fish with traits that foster successful stocks.
