Seen, Touched and Viewed under A Light

For most Indonesia people the title of this posting is probably a familiar phrase. The title of this posting was inspired by a public service ad that often appears on television about how to distinguish between real money with fake money.



Of course, this posting will not discuss about this public service ad, but the discussions were focused on the three words that became the icon of this ad, there are seen, touched and viewed underlight that can be applied in identifying the condition and quality of shrimp practically.

Practical knowledge on shrimp farming is needed in monitoring and identifying the condition and quality of shrimp daily as a basis for decisions making related to the technical treatments to be applied. Practical knowledge is usually conducted by using some functions of our senses to detect the changes that occur in the condition and quality of shrimps. One way that can be used is “seen, touched and viewed under a light" during the feeding monitoring or at the time of sampling. As for a detailed explanation of the meaning of “seen, touched and viewed under a light" are as follows:
  1. Seen, that is a direct visual observation to the shrimp activity level at that time. In normal conditions, the shrimps will look very active even be jumping around if given “shock therapy”, otherwise if the shrimps did not seem active though given “shock therapy” it can be indicated that the shrimps were affected by a problem. In addition, the condition of shrimps that needs to be seen are the completeness of the body, shell color and texture of shrimp feces.

  2. Touched, that is determining the condition of the shrimp by using our fingers. The trick is as follows: (a) take a shrimp sample and hold it by using the thumb and the index finger, then touch all parts of shrimp lightly on the tip of the tail of shrimp and feel if there are bumps in the tail. Shrimp in a normal condition at the tip of its tail was not found bumps; (b) after it is touched, press the shrimp's body using the two fingers to know the level of plasticity of shrimp body.

    Another thing to note is that when we hold the shrimp, the reaction level of shrimp in an attempt to break away from our grip. Shrimp in normal condition will seek to break away from our grip with a very active reaction

  3. Viewed under a light, namely the observation of shrimp condition by looking at the body's internal condition of shrimp under the sunlight. Shrimp body parts that can be viewed is the shrimp hepatopancreas and gut as an indicator of the condition of digestion and appetite level shrimp. A detailed explanation related to this has been explained in the discussion before.
The observation to shrimps condition in a practical as described above, should be performed daily, so that changes in shrimp condition can be recognized early. Although the observation method is very simple, but if we do it on a regular basis the results will be very decisive in decisions making related to technical treatment of cultivation.
