Aquaculture Technician Salary

An aquaculture specialist’s work environment usually involves office work as well as outdoor activity. Aquaculture farms and fisheries usually are in environments along the coast or waterways, and a specialist must spend time in those environments maintaining the aquaculture system and collecting data.

There are two overarching goals of aquaculture: maximizing growth rate and minimizing production costs. A rapid growth rate minimizes the time to achieve a marketable size and decreases risk. The reduction of production costs makes an operation profitable.

Environmental impact from aquaculture. Environmental degradation from aquaculture practices has been reported. The negative effects include organic pollution and eutrophication, a buildup of excess nutrients (primarily organic nitrogen and phosphorus) and wastes in an ecosystem.

Answer: It is important to monitor the growth of fish. Fish is one of the essential food that we eat. We need to properly monitor the water to safeguard the fish from any microorganisms that can harm it. Disease and sickness of the fish can harm also the consumer.

(i) freshwater pond culture; (ii) rice-fish culture or integrated fish farming; (iii) brackishwater finfish culture; (iv) mariculture involving extensive culture and producing fish/shellfish (e.g., oysters, mussels, cockles) which are sold in rural and urban markets at relatively low prices.

Growth rate can be measured by test sampling. Test sampling is the removal of fish from the dam (or tank) to assess their growth and health status. After the observations fish are returned to the water. Test sampling to determine growth rate is also the ideal opportunity to evaluate the overall condition of the fish.

Healthy Fish Require Monitoring Disease and sickness can spread easily among the animals, and because of the nature of these floating aquatic farms, the outbreaks can also spread to wild populations. Medical care and supplementary nutrients should be regulated to safeguard the other wildlife.

Fish in fish farms are exposed to very high health risks. Owing to the cramped conditions, pathogens quickly spread. In future, wireless miniature sensors implanted under the skin of the fish will help to prevent diseases, by monitoring and diagnosing their health.

• If buying whole fish, check the eyes.
