cara memeriksa kemurnian ikan
untuk memastikan apakah ikan murni atau tidak maka ada cara untuk memeriksanya yaitu dilakukan dengan cara pengambilan contoh darah ikan. darah ikan diambil dari pembuluh darah pada pangkal ekor dengan menggunakan sebuah alat suntik untuk dilakukan pengujian secara elektrophoresis di laboratorium.

cara menentukan kematangan gonad
beberapa cara menentukan kematangan gonad pada ikan :
a. menentukan kematangan gonad pada ikan jantan dilakukan dengan cara visual yaitu melihat urogenitalnya. Ikan jantan yang telah matang gonad ditandai dengan urigenitalnya yang memerah dan meruncing serta panjangnya sudah melampaui pangkal sirip ekor.
b. menentukan kematangan gonad pada ikan betina adalah dengan cara meraba bagian perut yang membesar dan terasa lunak serta bila diurut dengan tangan ke arah anus, ikan betina yang telah matang gonad akan mengeluarkan telur berwarna hijau kekuningan(TC 018)

uniformity shrimp
uniformity shrimp
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.

the color of pond water - water color criteria
the color of pond water - water color criteria
Criteria pond water color that can be used as a reference standard in the management of water quality is as below:
1. Color dark green pond water, which means indicate a dominance of Chlorophyceae with more stable nature of the environment and climate change because they have the time a relatively long mortality. Growth rate and relatively fast development is the potential occurrence of plankton boom in these waters.
2. Color brown pond water which means showing the dominance diatomae. This type of plankton is one supplier of natural feed for the shrimp, so the rate of growth and development of the shrimp relatively quickly. The level of stability is relatively less plankton, especially in winter conditions with the high rainfall, so the potential collapse of plankton and if not carefully managed water quality stability will be volatile and would interfere with the comfort level in the shrimp ponds.
3. Color brownish green pond water, which means showing dominance happens is the combination of the Chlorophyceae and is stable diatomae supported by the availability of natural feed for the shrimp.
Standard color of pond water as described above is a practical reference for identifying species of plankton in an attempt detection of water quality problems at an early stage. In addition to these standard colors there are some pond water colors usually found in shrimp cultivation activities, which include:
1. Color yellow pond water, which means indicate a phytoplankton species dominance cyanophyceae. In conditions like these pond waters are usually more pale colored shrimp than is usually accompanied by a decrease in appetite shrimp and if not immediately anticipated may cause damage to the shrimp hepatopanchreas.
2. Color green pond water vanished, which means indicate a phytoplankton species dominance dynophyceae impact is relatively similar to point (1).
3. Color blue-green pond water, which means indicate a dominance of blue green algae relative impact equal to the point (1).
4. Camouflage green color, in this case as if the pond greenish but basically no / less contain plankton. This happens usually in ponds which contain the seeds was very poor but planktonya fertilization activities continue, so the resulting color is the color because of the weather. This incident can be identified by measuring the brightness of the pond waters are usually very high, or to see the color of the water in a water mill was operated.
Identify types of plankton in the waters of the pond in a practical way to see the color of the water as described above to be supported by observation and laboratory analysis on a regular basis to obtain more accurate results. This activity is done by taking water samples and samples of shrimp from pond map map-whether the problem or not affected by the problem, so the comparison can be drawn.
