Hatchery Design and Construction
Extensive experience with both freshwater and saltwater facilities makes Innovasea the world leader in hatchery design and development. Hatcheries are where it all begins. Every aquaculture facility needs eggs or juveniles to supply its nursery or farm. While hatcheries traditionally feature flow-through systems, more and more are looking at RAS or partial RAS systems to minimize water use, reduce discharge volumes, improve thermal control and increase throughput. Innovasea knows that marine hatcheries are often more technical and require different equipment, especially if they use RAS or partial RAS systems. The water chemistry of saltwater affects the performance of both biological treatment equipment biofilter and gas management solutions and the overall system infrastructure pump impellers, tanks and material handling equipment.

The growout requirements are such that the hatchery spawning runs need to be continuous to constantly supply the culture requirements of the growout farm. The growout farm requires , fingerlings every month.
A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. Some species that are commonly raised in hatcheries include Pacific oysters , shrimp , Indian prawns , salmon , tilapia and scallops. There is much interest in supplementing exploited stocks of fish by releasing juveniles that may be wild caught and reared in nurseries before transplanting, or produced solely within a hatchery. Fish and Wildlife Service have established a National Fish Hatchery System to support the conservation of native fish species. Hatchery production confers three main benefits to the industry: 1. Out of season production Consistent supply of fish from aquaculture facilities is an important market requirement. Genetic improvement Genetic modification is conducted in some hatcheries to improve the quality and yield of farmed species.
Design and construction of hatcheries. Methods of seed production in aquaculture vary considerably with the species under culture and the state of technology, as well as with the level of operation as, for example, extensive or intensive and the number or frequency of crops. Where the techniques for arti ficial propagation are still to be developed or perfected, or where it is feasible and economical to collect eggs, larvae or fry from natural breeding areas, sophisticated hatchery systems are not often used. As is only to be expected, there are different types of hatchery facilities in use, depending on the species, locality and investment capabilities of the aquaculturists. However, the basic requirements are about the same: there has to bethe necessary facilities for holding or rearing an adequate brood stock, spawning or stripping and fertilization of ova, incubation of fertilized ova and rearing of larvae to the required stage for transfer to nurseries or other culture facilities.

This document provides technical guidance on how to improve the health and quality of postlarvae produced in hatcheries through improved facility maintenance and husbandry, broodstock maturation, larval rearing, feeding, water quality management, biosecurity and health management, using interventions at different points of the hatchery production process.
