As already explained, in a population of shrimp in ponds in general can be classified into 3 (three), namely: (i) shrimp uniform, (ii) the uniformity of the shrimp were, and (iii) the level of bad shrimp uniformity. In addition to these explanations, the understanding of how management alternatives based on conditions encountered in the field.
Broadly speaking, management needs to be done related to the uniformity of shrimp feed includes program management and water quality management (assumption: benur have used relatively uniform, both size and age). Alternative management of the above conditions are as follows:
1. Shrimp uniform. If the population of shrimp in the shrimp ponds showed relatively uniform size, so technically that management needs to be done is how to maintain these ideal conditions until the shrimp is ready to be harvested in a normal way. Management of the feed program should always follow the shrimp need level and the amount of feed given daily in accordance with the density of shrimp in the pond. In this condition is usually the amount of feed given to show that is always increasing trend based on time (except shrimp in a periodic moulting condition). Feeding programs must be carefully managed on the basis of observations made (by check or sampling Ancho).
In addition to food programs, alternative management needs to be done is the quality of pond water. Usually there is a correlation between the uniformity and quality of water shrimp (assumption: the feed program was implemented as mentioned above), namely: the size of the shrimp will be relatively uniform, if the management of water quality in accordance with the requirements of shrimp. The effort needs to be done in water quality management is how to maintain pond water quality, relatively stable and no fluctuations change the pond water quality. Explanations related to the management of water quality ponds have been described in previous discussions.
2. Shrimp with uniformity level was. In this condition technically manage to do is how to prevent the level of uniformity is not worse and efforts to improve blood circumstances better. Feed program should be reviewed applicable mainly related to the size composition of shrimp feed and the amount of feed given. The composition of the feed size and the amount can be roughly estimated by observation at the time of sampling and check Ancho. Estimated percentage does include the density of each size of shrimp in a population, which can be estimated size of the feed to be used and the amount to be given in a single daily feeding frequency. The composition should be adjusted back by referring to the observations made. If the level of uniformity of shrimp which leads to a better level then the given feed size would be less.
Example: in a population of shrimp in the pond has 3 different sizes, given the feed should consist of 3 types of feed of different sizes to suit all shrimp sizes. If uniformity of shrimp in these ponds was led to a better level, for example, be 2 types of shrimp size, the composition of the feed size should also be given 2 types of feed size. Pond water quality management is carried out under these conditions relatively similar to item no. 1 mentioned above.
3. Level of bad shrimp uniformity. In this condition technically manage to do is how to prevent the shrimp population in the pond is not as drastic shrinking (due process of cannibalism). Programs that need to be applied feed primarily on items such as no explanation. 2, only the size of the species composition of feed used in one feeding frequency will usually be much too. In a more extreme handling, sorting is usually done directly shrimp size during the check Anco or sampling activities at the time (not recommended). Terhdap done sorting shrimp with sizes that are considered too far behind shrimp with normal size, so the expected level of uniformity in the shrimp ponds will be better although the density decreased. Pond water quality management is carried out under these conditions relatively similar to item no. 1 mentioned above.
Alternative treatment above is essentially an effort to maintain, improve and prevent a condition to the level of uniformity in a population of shrimp in ponds can lead to conditions as expected, especially at an optimal output.
