Two Scottish consortiums, backed by the Scottish Aquaculture Innovation Centre (SAIC), are embarking on ambitious initiatives to improve gill health and resilience among farmed Atlantic salmon – one of the industry’s most significant challenges valued at £3.5 million.

Off-shore mariculture promising alternative to land-based and coastal aquaculture

Blood is an important animal by-product and an attractive source for animal feed production. However, the outspread of bovine spongiform encephalopathy led to strict regulations on the usage of animal by-products in animal feed. Although, the ban on certain processed animal proteins has been...

Infection with Streptococcus agalactiae causes mortality and major economic losses in Nile tilapia (Oreochromis niloticus) farming worldwide. In Brazil, serotype strains Ia, Ib and III have been isolated in streptococcosis outbreaks, but serotype Ib is the most prevalent. Vaccination is considered...

The impacts of variation in fish filleting by-products origin including white muscle (cod), dark muscle (herring) and farmed fish (salmon) on physicochemical and gel-forming properties of protein recovered using the pH-shift method were studied. The effects of different solubilization pHs (acid or...

Background: Parasitic salmon lice (Lepeophtheirus salmonis) cause high economic losses in Atlantic salmon farming. Pyrethroids, which block arthropod voltage-gated sodium channels (Na_v1), are used for salmon delousing. However, pyrethroid resistance is common in L. salmonis. The present study...

Offshore mariculture could enable increased seafood production and economic development while alleviating pressure on coastal ecosystems and wild fisheries. In the Caribbean, however, an integrated assessment of the ecological and economic potential for mariculture in the region is lacking. We...

The aim of this study was to evaluate the effectiveness of borax (BX) against heavy metal exposure on the transcriptional and biochemical reaction in vivo and alleviating effect on gill and liver tissues of rainbow trout. Due to this aim, fish were fed with different level of BX and/or copper (Cu)...

An 8-week feeding trial was conducted to evaluate the growth performance, feed utilization and physiological status of obscure puffer, Takifugu obscurus (13.03±0.14 g) fed diets in which fish meal (FM) was replaced with various levels of dehulled and defatted soybean meal (SBM): 0% (SBM0), 15%...

Cadmium is a persistent contaminant of surface waters. The effects of cadmium on early life stages of fish are not well understood, although they are often disproportionately affected by contaminants. The objectives of this study were to examine effects of chronic exposure to environmentally...
