Aquaculture Farm Manager Question:

This depends on the animal. For instance a salmon spends 1 ½ years in the hatchery and then 1 ½ - 2 ½ years in marine net pens. Oysters spend about 3 months in the hatchery then 7-8 months in juvenile culture systems, and a further 1 ½ - 2 ½ years growing to market size. Blue mussels can grow to market size in as little as 1 year and take up to 3 years depending on seed size, water temperatures and culture techniques. Marine worms take about 6 months to grow to market size.
