Shrimp farming and the RAS system

Shrimp is one of the most in demand crustaceans worldwide, which is why Derwent want to pay special attention and shed some light on the cultivation of one of the most consumed aquaculture products. There are more than 2000 species of shrimp, although only a few have shown great potential for cultivation and are those that are marketed worldwide. 

The species that are most cultivated today are Litopenaus vannamei and Penaeus monodon. Although it is true that there are other species that have been widely cultivated in the past, such as Fenneropenaeus chinensis and Marsupenaeus japonicus, these have been displaced due to problems with different pathologies, in addition to the fact that L.vannamei and P.monodon have shown genetic advantages in terms of growth rates and resistance, at the same time they present ease for the development of lines free of specific pathogens.

Currently there are different systems and techniques for shrimp farming. The tools available for farming continue to improve and evolve to increase the quality and sustainability of shrimp farming. Currently available growout technologies are evolving towards two main trends, in addition to traditional extensive pond culture, RAS systems and biofloc technology. These systems represent an evolution towards the reduction of water consumption, at the same time that they allow Derwent to move the production centers to the consumption areas, making the industry more sustainable by reducing the costs and effects of transport.

Derwent work to develop RAS systems for different aquaculture species, presenting a series of advantages over other systems, such as increased biosecurity and traceability and a significant improvement in production efficiency, with high densities and temporary production control. This allows better planning and access to the market according to the market needs. The main disadvantages are a higher initial investment cost and the need for technical experience in handling. Although with the evolution and cheaper technologies and the experience of companies such as Derwent and Dibaq, RAS technologies will be more present in the aquaculture market every day.

Five young chefs announced as this year’s BIM Taste the Atlantic Ambassadors

Five young chefs have been announced as the Bord Iascaigh Mhara (BIM) Taste the Atlantic Young Chef Ambassadors for 2022. The programme, now in its second year, was created by BIM, and is a collaboration with Chef Network and Fáilte Ireland as a way to give emerging young chefs in-depth experience of the Irish aquaculture, seafood, and coastal tourism sectors. During the immersive four-month programme, each of the chefs will embark on a seafood journey along the Taste the Atlantic trail, familiarising themselves with the salmon, oyster and mussel producers working along the Western seaboard.

This week the chefs visited seafood producers in the West of Ireland, including a visit to the Burren Smoke House, Co Clare where owner and producer, Birgitta Curtin gave a demonstration at her Irish salmon smokery. This was followed by a visit to Flaggy Shore Oysters in Co. Clare where the chefs learnt about oyster production, and a visit to Moran's Oyster Cottage in Kilcolgan, Co Galway to further their understanding of the importance of oyster production in the area.

Additional field trips to Connemara and West Cork are included as part of the programme and the chefs will spend two days developing their culinary skills with Michelin star chef JP McMahon at his Aniar Restaurant in Co Galway.

Master fishmonger Hal Dawson will also provide training to the chefs in fish quality and preparation skills at the BIM Seafood Innovation Hub in Clonakilty, Co Cork where they will also attend a culinary business workshop.

One of the unique features of the BIM Taste the Atlantic Ambassador programme is the pairing of chefs with seafood producers helping them to gain a deeper understanding of the provenance of Irish seafood.

The programme will culminate with an event at the Galway International Oyster and Seafood Festival in September.

Details about the 2022 young chefs are as follows:
