£1.7m study seeks to unlock secrets of salmon sea lice resistance

£1.7m study seeks to unlock secrets of salmon sea lice resistance

Scientists in Scotland have been given £1.7 million for a study to identify genes that could make Atlantic salmon resistant to sea lice.

Standardised gill scoring can lead to better fish health

Standardised gill scoring can lead to better fish health

Scientists have developed a standardised gill scoring system which they say can substantially contribute to the development of robust mitigation strategies for amoebic gill disease (AGD) and other gill problems.

Aquaculture genetics star Houston joins Benchmark

Aquaculture genetics star Houston joins Benchmark

One of the world’s leading aquaculture genetics experts, Professor Ross Houston, is to join salmon ova provider Benchmark Genetics from the beginning of March next year.

New advances in study of genetic resistance to ISAV

New advances in study of genetic resistance to ISAV

Researchers in Scotland and Norway have discovered a quantitative trait locus (QTL) – a small region of DNA - that would explain about 3% of the variance in resistance to the infectious salmon anaemia virus (ISAV), and that could be prioritised in breeding selection.

Cheap and quick tests being developed to detect shellfish diseases

Cheap and quick tests being developed to detect shellfish diseases

Aquaculture researchers in Scotland are developing a PCR method that will help detect the presence of a range of diseases and biofouling species affecting oysters and mussels, in a project that could be a significant boost to the health and wellbeing of the shellfish.

Researchers identify disease resistance gene in salmon

Researchers identify disease resistance gene in salmon

A gene with a major role in resistance to Infectious Pancreatic Necrosis Virus (IPNV) that can cause high mortality levels in farmed salmon and trout has been identified in a study by a team of scientists.

Looking back, thinking ahead: Ross Houston

Looking back, thinking ahead: Ross Houston

Fish Farming Expert has asked individuals connected to the salmon farming industry about their year, and what they hope for in 2021. We start the series today with the thoughts of Professor Ross Houston, personal chair of aquaculture genetics at Edinburgh University’s Roslin Institute.

Salmon gene breakthrough may offer better breeding

Salmon gene breakthrough may offer better breeding

Genetic selection programmes that can lead to gains in the production of farmed fish may be enhanced by new research into Atlantic salmon which has highlighted a previously untapped source of genetic variation.

Cutting the lice problem with ‘genetic scissors’

Cutting the lice problem with ‘genetic scissors’

An international effort to discover if the resistance that Pacific salmon have to sea lice can be gene edited into Atlantic salmon has begun.

Black soldier fly growth rate ‘can be doubled in a year’

Black soldier fly growth rate ‘can be doubled in a year’

Scientists in Scotland may be able to double the growth rate of the black soldier fly (BSF) within a year, making insect protein a more competitive and viable source of feed for farmed fish.

Inaugural Scottish aquaculture and animal conference postponed

Inaugural Scottish aquaculture and animal conference postponed

An inaugural conference on animal health, agritech and aquaculture that was due to be held in Edinburgh later this year has been rescheduled because of the Covid-19 pandemic.

£500k on offer for start-ups to boost aquaculture sustainability

£500k on offer for start-ups to boost aquaculture sustainability

Early career researchers and industry professionals with an interest in science entrepreneurship are being offered up to £500,000 of investment in start-up companies that can “massively improve” the sustainability of aquaculture.

Cut-price genetics help search for lice-resistant salmon

Cut-price genetics help search for lice-resistant salmon

A new, cost-effective selective breeding method is being developed by a Scottish research consortium that could improve salmon resistance to sea lice.

Scotland-Chile knowledge swap furthers fight against gill disease

Scotland-Chile knowledge swap furthers fight against gill disease

An international collaboration between aquaculture experts from Scotland, Chile, and the research and development (R&D) team from Hendrix Genetics has taken what scientists say is a significant step toward the early detection and potential treatment of complex gill disease (CGD).
