Microalgae are of fundamental importance for life in the oceans. With their photosynthesis they are the first link in the marine food chains upon which the existence of life in the oceans is based. Under certain conditions, however, uncontrolled mass development of the tiny algae can occur. The resulting algal blooms often have serious ecological and economic consequences and can even be toxic.

Made-to-measure for aquaculture
The African sharptooth catfish Clarias gariepinus is a hardy fish of modest needs that is not particular about its diet. Moreover it is an accessorial air-breathing fish that is sometimes to be found living in groups in the most confined spaces at great densities. Its protein- and omega-3-rich fillet tastes good, is healthy and can be processed in many different ways. All this makes C. gariepinus an ideal candidate for aquaculture and it is produced in considerable quantities worldwide.

Progress must be better conveyed
From simple earth ponds to offshore net enclosures and computer-controlled RAS: no other area of food production has changed so rapidly in such a short time as aquaculture. The pace of development is overwhelming for many consumers and outside the industry there are enormous gaps in knowledge which often leads to misunderstandings and even raises fears. More explanation and elucidation will be necessary to enable a constructive dialogue.
The term aquaculture has had some quite different meanings throughout history. It first appeared in 1855 in a newspaper article in connection with the storage of ice for cooling purposes in the summer months, and later on it was also used for irrigation practices in agriculture. Since the end of the 19th century (around 1890), however, it has increasingly been understood as a collective term for the methods used for the cultivation of aquatic plants and the rearing of various aquatic animal species. These mainly include fish, molluscs and crustaceans, but also aquatic reptiles, amphibians and some invertebrates, including echinoderms such as sea cucumbers or sea urchins. To be successful, aquaculture requires precise knowledge about the biology of the organisms produced, their food requirements, and their daily needs. In contrast to capture fisheries, which exploit fish stocks as a common pool resource, the plants and animals produced in aquaculture are the property of the producer or company.

A new publication in Spanish, Acuicultura marina. Granjas marinas de peces. Diseño y operación (Marine aquaculture. Marine finfish farms — Design and Operation) has been produced following a year’s work by the Spanish Association for Standardisation (UNE) and APROMAR, the Spanish Aquaculture Producers Association. The publication covers the design, construction, and proper maintenance of marine aquaculture farms to reduce possible technical and operational failures and to avoid the possibility of escapes caused by accidental impacts during daily operations or by unexpected events. It lists good practices that fish farmers can implement to make Spanish marine aquaculture more sustainable.

Adris Group, a major player in Croatia with activities in tourism, insurance, real estate, and healthy food services is behind Croatia’s largest producer of farmed fish, Cromaris. The positive development the group has shown over the last years mean that additional investments will be made into the sector. In the next three-year period, Adris Group plans to invest more than EUR30 million in the food sector through its ownership of Cromaris. Cromaris had a strong 2019 showing an 8% increase in sales for the first nine months of 2019 reaching a net profit of HRK13.2 million (EUR1.8 million), 80% of which is generated on foreign markets. In 2019, Cromaris will reach sales levels of nearly 10,000 tonnes of fresh fish. With the added investment Adris wants to transform Cromaris into a leader in the Mediterranean fish business.
An improved range of starter feeds for trout has been created following extensive research that provide key nutrients while improving water quality. Alltech Coppens TOP fry feed has an optimised ratio between digestible protein and digestible energy. This results in better performance with higher protein utilisation and lower ammonia excretion, leading to improved feed efficiency and better water quality. Dr Philip Lyons, Global Aquaculture Research Manager at Alltech Coppens says the feed not only improves performance during a critical phase but does so sustainably.
