3B - GIS-BASED ANALYSIS OF AQUACULTURE SITE SELECTIONWisconsin Land Information AssociationAllen Brandt, UW Stevens Point GIS Center & College of Natural Resources
Aquaculture is one of the fastest growing food production systems in the world.The aquaculture industry in Wisconsin,
comprised of approximately 2,000 registered fish farms, contributes over $7 million to the state’s economy annually.
There are many species of game, food, and bait fish cultivated throughout the state in a variety of production systems. In
recent years, the growth of the aquaculture industry in Wisconsin has slowed and the number of registered fish farms is
beginning to decrease.The reason for the decrease in fish farms is not known, but it could be from the tough economic
times, high costs of production, limited markets, environmental restrictions, or the site location of the fish farms.The
objective of the study is to determine if the site location characteristics play a part in the success of the fish farm
operation.The utilization of Geographic Information Systems (GIS) to create an evaluative model examining the
environmental and socio-economic characteristics of current registered fish farms and those that have closed.The
characteristics considered are land cover, soil types, elevation, water quality and source, and proximity to infrastructure
and potential markets.The evaluative model will then be used to create a predictive model using a multi-criteria
evaluation procedure using a GIS.The predictive model will be able to determine suitable locations for sustainable
system-specific and species-specific aquaculture facilities.
Economics of fish hatcheries and grow outAmit JanaThis document discusses the economics of fish hatcheries and grow-out facilities. Key factors to consider when constructing a hatchery include the layout, type of fish to breed, and water supply and quality. Hatcheries produce juvenile fish to support aquaculture by transferring them to grow-out systems on farms. Grow-out facilities allow hatchery fish to reach harvest size. Hatcheries can help ensure consistent fish supply, support genetic improvement, and provide healthy, uniform fish seeds for farming when sited properly and run effectively.
Fish Hatchery the B-AreaLela MyThis presentation summarizes the internship of Noorlela Bt Md Yassin at the Borneo Marine Research Institute Fish Hatchery. The hatchery is divided into several areas for broodstock management, juvenile rearing, and culture of different species. It utilizes a recirculating aquaculture system and focuses on species like groupers and seabass. Routine activities include cleaning, feeding, and treatments. Artificial production involves selecting broodstock, hormone injections, stripping eggs and sperm, and fertilization. The internship provided hands-on experience in hatchery management and aquaculture.
Carp hatcheryHem ChudasamaThis document discusses techniques for induced breeding of carp species in hatcheries. It describes the collection of pituitary glands from brood fish and injection of hormones like HCG to stimulate breeding. After conditioning, brood fish are weighed and injected, then placed in hapas or tanks. Water temperature between 25-28°C and oxygen levels of 5-9 mg/L promote successful spawning. Eggs are incubated in glass jars or Chinese circular hatcheries consisting of overhead tanks, spawning tanks, incubation tanks, and receiving tanks, and fry are reared in earthen ponds.
