EXPERT TOPIC had us dip the soles of our shoes in a disinfectant solution before we entered the hatchery facility. He explained that such basic hygiene practices are required as the site of the hatchery is GlobalGAP certified. GlobalGAP is a Global Food Safety Initiative (GFSI) recognised standard that assures buyers that basic food safety and sustainability practices have been upheld. The GlobalGAP (Good Agricultural Practice) certification is necessary as some of the customers of the hatchery supply fish to supermarkets. The entire farm complex is not GlobalGAP certified due to the difficulty of upholding the standards in areas where the farm functions as a tourist attraction visited by families with children and babies in strollers. The hatchery is also RSPCA assured, and holds QTUK accreditation.
The hatchery
The hatchery complex is comprised of three buildings and multiple atmosphere control marquees. Each of these components is necessary to produce eggs and raise them into triploid females of a size where they can safely be introduced to the farm (more on “triploids” later).
Fertilisation room
The place where science and skill play the largest part is the fertilisation room. This is where Martin collects the eggs and the sperm from female-only fish. A female population is preferred for trout species as males mature sexually while they are quite small and by time they reach market size their meat is grey and watery. For this reason, a monosex culture of so-called “triploids” is preferred.
Save time, frustration and money. INTRODUCING WENGER’S NEW MODULAR EXTRUSION INTEGRATION (MOXI) Wenger’s plug-and-play solution for extrusion process design and implementation reduces system installation time by up to 60 percent. It literally eliminates the need to design interconnection piping between devices, and reduces the requirement for local contractors – who may be unfamiliar with current extrusion process design standards. With MOXI, there are no floor-mounted extruder components; so the extruder barrel is clear of all system attachments, while providing ready access for maintenance, cleaning and sanitizing. Know more about the extreme benefits and customized options of MOXI. Email us at info@wenger.com today.
