Shrimp farming development

Among the first commercial shrimp farming development projects in the... 

As already mentioned above, research into the needs of various animal groups for healthy, fast, and controlled development has led to the definition of preferred feed components and the development of complex rations, which do not only provide food but also guarantee animal health and growth. This is particularly true for feeds for specific animal farming technologies, such as the already traditional feed lot formulations for cattle or the more recently formulated nutrients for fish and shrimp farming, and for pet foods. 

Using hatchery-produced seed was expected to increase the reliabihty of shrimp farming, and shrimp hatcheries were developed in both hemispheres. PL were produced in land-based hatcheries from wild-caught broodstock. These PL were genetically wild animals because their parents... 

It is often said that the three most important factors in real estate valuation are location, location and location. This is also true for an SPF hatchery. The first step in an SPF hatchery biosecurity plan is site selection. A shrimp hatchery requires abundant supplies of high quality sea water. High quality sea water is not polluted with industrial or urban pollutants and is far from other shrimp farming activities. In some countries where a successful hatchery develops others soon follow, and this is a negative factor in SPF hatchery site selection. An extreme example of this can be found in Wenchang, China, a small coastal town on Hainan Island. More than 600 shrimp hatcheries operate in a coastal area less than 50 km in length. It is very difficult for a hatchery operator to maintain good biosecurity in such a location.

Despite the apparent advantages of L. stylirostris over L. vannamei in terms of size at harvest (Fig. 11.1), growth rate, and ease of culture, its extreme susceptibility to IHHNV severely limited its culture potential in the Americas and this ultimately led the early pioneers of shrimp farming in the Americas to develop L. vannamei as the dominant farmed species.

All these reasons led to the evolution of a large, highly efficient industry in which so-called feed mills formulate and process special nutriments for different groups of animals. While, at the beginning, this development was centered around the traditional domestic livestock, mammals and fowl, today s products include feeds for new food production technologies, for example fish farming, where fish or shrimp are raised and fed for optimum results. Another important new market is pet food. Tab. 6.5-1 is a summary of the most important reasons for size enlargement in the animal feed industry.
