Hatcheries

Although cleaner fish are proving an effective and environmentally friendly way of removing sea lice on salmon farms, they can carry pathogens that can cause disease in both the cleaner fish and salmon. Speaking at Aquaculture Europe, 20-23 September, Edinburg…

Salmon farming companies have been switching their focus to the production of much larger smolt as a strategy for reducing netpen grow-out time and for reducing problems with sealice. Since recirculating aquaculture systems, with their warmer year round operat…

Maintaining a stable and favorable gut microflora is of crucial importance to minimize the impact of disease events and to optimize digestive efficiency in shrimp, resulting in improved survival and productivity. The present paper illustrates the potential of …

The European ban on the use of antibiotic growth promoters in livestock, and the subsequent search for alternatives, has revealed the importance of gut health and the development of a stable, favorable gut microflora, on feed efficiency, overall performance an…

Cultured marine fish larvae are most often fed rotifers (Brachionus sp.) the first few weeks after first-feeding. However the nutritional value of rotifers is generally inferior to the natural diet of marine fish larvae which is comprised of zooplankton, mostl…

In early 2014, a trial to evaluate the effects of a mixture of Bacillus strains on early mortality syndrome bacteria during the larviculture and nursery phases for shrimp was carried out at a commercial hatchery in Mexico, write Oliver Decamp et al, INVE Aquac…

Extracellular Polymeric Substances (EPS),1 or exopolymers, play vital roles in the productivity of commercial hatcheries, yet have received little attention in aquaculture outside of their role in the biofilters of recirculating systems, write A. Joycea and S.…

The main objective of this study by Hooi Ling Khaw et al, Wageningen University, Netherlands, is to quantify the genetic and non-genetic indirect effects for harvest weight in the GIFT strain of Nile tilapia.

This article offers an introduction to the new environmentally friendly and highly productive closed fish farming systems, by Jacob Bregnballe, FAO.

IRTA researcher Enric Gisbert explains what the Feed Conversion Ratio is, how to calculate it and its importance for fish production.

This article is the second in a two-part series about Japan's Kinki University Fisheries Laboratory. The first article looked at the history of the facility and how tuna is being farmed. This article focuses on the challenges the Laboratory faces, and some fut…

The Fisheries Laboratory of Kinki University in Japan has found a possible way to address the problem of declining tuna stocks by cultivating completely farm-raised Pacific bluefin tuna. In the first of two articles, Bonnie Waycott explains how it's done.

Increased aquaculture production will be needed in future to improve food security, but what role can genetically improved farmed fish species play in increasing productivity? This study from Ingrid Olesen and colleagues investigates.
