Due to nitrate accumulation during nitrification and low water-exchange rates in recirculating aquaculture systems (RAS), nitrate levels can build up. Hendrik Monsees has therefore investigated the effect that exposose to high nitrate concentration has on juve…

Although the effects of fish density on the performance of fish have been widely studied, there has been little work done into the effect of cage size on seabass performance, said Athanasios Samaras speaking at Aquaculture Europe 2014, writes Lucy Towers, TheF…

Fish are not silent creatures. Just like the terrestrial world, theres a veritable symphony of sound echoing under the sea.

Fish is especially rich in essential omega-3 long-chain polyunsaturated fatty acids and micronutrients, including bioavailable calcium, iron and zinc. Fish features prominently in the diet of most, especially poor, Zambians. Despite this, its significance in t…

Pole-and-line fishing is considered to be a sustainable method for catching tuna. However, the reliance on baitfish, which are commonly very variable in their availability, has the potential to introduce unsustainable elements to the fishery, write Arun Padiya…
