Family x environment interactions exist in farmed salmon. We recently found pre-harvest maturation is one trait that is not consistent between the same families reared under different smolt environments (left panel below). We also see male maturation in land-based "large-smolts" really kicks off once fish go over 250g when kept on steady 13°C and continuous light from first feeding (the right panel in the graph below). You can reduce this by using fish that are homozygous for the late maturing vgll3 allele (LL in the figure, compared to homozygous early (EE) or heterozygous fish (EL)).

It required a willingness to embrace change and venture into uncharted territory. Undeterred by the unfamiliarity of the aquaculture landscape, Ruben dove headfirst into learning the intricacies of aquaculture and salmon genetics. He approached this new chapter with the same diligence and attention to detail. Read the full story about Ruben here: https://lnkd.in/gDfVUEmb #benchmarkgenetics

Aquaculture farms are critical in meeting the rising global demand for fish and seafood—now and in the future. One key to increasing aquaculture production is the ability to control and supplement the oxygen level in your water. Messer’s pioneering FARMOX™ solutions allow you to do just that, leading to higher stocking densities, lower fish mortality, feed cost reductions of up to 20% and more.

Our MBA Study Week in Scotland! Day 1 Highlights: Exploring Marine Science and Aquaculture in Oban Today, we had the incredible opportunity to visit the CGPA Algae Collection at the Scottish Association of Marine Science (SAMS) in Oban. It was fascinating to learn about the diverse variety of algae and the unique conditions each species requires to thrive. Following this, we toured the Barcaldine Scottish Sea Farms Hatchery. Here, we met with Markus, who provided an in-depth explanation of the salmon lifecycle from eggs to adult salmon. Observing the tiny salmon eggs and understanding the importance of precise temperature, oxygen, and nutrition at every growth stage was enlightening. We learned that at the alevin stage, salmon need 2-10 weeks to transition to the fry stage. One of the most intriguing aspects was discovering the various breeds of salmon, each requiring tailored treatments to ensure optimal growth. A huge thanks to SAMS and Scottish Sea Farms for the insightful tours and the valuable knowledge shared! #MarineScience #Aquaculture #SalmonLifecycle #AlgaeResearch #SustainableFarming #ObanExploration #RWU

💡Lights out! And stop eating your little brother! 🐟 Despite their charismatic cuteness, lumpfish, valuable as “cleanerfish” to the lucrative salmon aquaculture industry, can be aggressive toward each other, presenting a challenge to raising them. But new research from UNH found that changing both the lighting and the density of lumpfish in hatchery tanks can reduce this feisty behavior (which includes cannibalism). The researchers found that when small lumpfish had 12 hours of light and 12 of darkness, instead of constant light, and when there were fewer of them in a tank, they reduced instances of aggressive tail fin nipping. “Understanding the factors that exacerbate lumpfish aggression, and providing guidelines for mitigating this behavior to aquaculturists, are essential for increasing hatchery production and rearing efficiency,” says research associate professor Elizabeth Fairchild, who published this research in the North American Journal of Aquaculture with Brittany Jellison, assistant professor of biological sciences, and master’s student Shelby Perry.

The 4th 𝗜𝗻𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗙𝗶𝘀𝗵 𝗖𝗼𝗻𝗴𝗿𝗲𝘀𝘀 took place in the State of Paraná, Brazil, in late September. Covering all sectors of the aquaculture and fishery industries, the conference had 4,000 attendees and featured more than 40 invited speakers from 18 countries. Representing Aquabyte was Gabriel Coelho de Moura from our Chilean office, who delivered a talk titled 𝘛𝘩𝘦 𝘝𝘢𝘭𝘶𝘦 𝘰𝘧 𝘈𝘳𝘵𝘪𝘧𝘪𝘤𝘪𝘢𝘭 𝘐𝘯𝘵𝘦𝘭𝘭𝘪𝘨𝘦𝘯𝘤𝘦 𝘪𝘯 𝘎𝘭𝘰𝘣𝘢𝘭 𝘈𝘲𝘶𝘢𝘤𝘶𝘭𝘵𝘶𝘳𝘦, highlighting how data-driven fish farming enhances welfare and boosts production efficiency. #datadrivenfishfarming #datadrivenfishwelfare #aquaculturesouthamerica

Could this discovery help end the threat from sea lice to the salmon industry? : Nofima study sheds light on host-parasite dynamics, aiming to bolster resistance in farmed salmon. New research led by Nofima, the Norwegian Institute of Food, Fisheries and Aquaculture Research, has uncovered the role chemical signals play in attracting sea lice to Atlantic salmon, offering insights that could shape the future of aquaculture. https://lnkd.in/eJP9WsKd
