摘要: Mussel culture largely depends on seed and feed from the natural environment. This paper focusses provisioning efficient use of these resources in mussel production. Approaches technologies for supply production are described different techniques. includes potential interactions conflicts with Three methods used to provide seed: wild harvest, suspended collectors hatchery Harvest seaweed (in New Zealand) or beds is still a major source some areas, costs low but often unreliable. Most research concerning spat collection deals comparison types collectors, settlement cues problems biofouling. Hatchery more expensive, hatcheries opportunity selective breeding triploid giving product an added value. The challenge bring line actual sale value seed. Monitoring genetic diversity can give insight whether collector growth survival negatively affected by reduced diversity. Grow-out occurs bottom culture, bouchot off-bottom longline raft culture. In bottom-culture, focus developing better seeding techniques, predator control optimizing practices such as timing relay, substrate harvest. For technical developments directed mechanical increase efficiency size grading, restocking, harvesting processing. Innovation growing-out techniques towards investigation optimal stocking densities, material type configuration farms. Production increases rope related sources mortality differences rate. Growth rate mussels higher off than when submerged intertidal. Mussels Perna genus found have lower Mytilus genus. Efficient should aim at reduction losses rates. Important tools adjusting densities relation system design, reducing stress, applying thinning out relay.
