Practical Parameters of Shrimp Feed Quality

Shrimp feed is one of the important parameter on shrimp farming, because it is a biggest contributor of production cost than other parameters (especially on intensive shrimp culture). In connection with that logical basic hence it is on the right track to shrimp farming actors have a knowledge concerning shrimp feed quality parameter in order to avoid a failed decision in determining shrimp feed to be used.

Mainly, shrimp feed that to be used can accommodate on two components there are: (i) shrimp need level, and (ii) shrimp behavior. Shrimp need level to feed is not only including how much feed quantity that capable to be consumed by the shrimp but also have to include nutrient content that required by shrimp for growth. Meanwhile shrimp behavior component include food habit (kind of feed that usually consumed by shrimp) and feeding habit (how do the shrimp consume their feed) so this component also follow to determine the parameter of quality of shrimp feed (explanation related to food habit and feeding habit already discussed before).

Based on above mentioned description, hence some practical parameters which able to be used on determining the quality of shrimp feed are:
  1. Nutrient content of shrimp feed. Mainly, the nutrient content on shrimp feed have to cover: (i) protein, (i) fat, (iii) fiber, and (iv) ash, also feed moisturize factor. Nutrient content is usually mentioned by producer at feed package, also including produce code and expired date. (This discussion will not explain concerning understanding and function from each the nutrient elements, because more instructing to knowledge concerning with nutrition science).

  2. Solubility level of shrimp feed in water, that is the time required by the feed to be able to dissolve underwater. This parameter can is also said as rubbery level (hard or soften) of feed texture, or equally more harder texture of shrimp feed, hence soluble level of shrimp feed also will longer.

    Solubility level of shrimp feed in water have relationship with shrimp ability on tolerance to rubbery of feed texture to be consumed. If feed texture too hard, usually shrimp will not consume t and will the feed and their try to search of source of other feed. On the contrary if feed texture too soft, hence the feed will be dissolves soon without have time to be consumed by shrimp.

  3. Feed aroma. This parameter related to shrimp behavior in looking for the food source more relying on smell sense. Feed aroma shall can give smell stimulus that able to draw the shrimp to consume it. If the feed not have aroma that able to draw the shrimp hence the feed will castaway in water at this condition can generate the accumulation of useless feed at pond bottom.
The three parameter like mentioned above is basic parameter which better be comprehended by shrimp farming actors, so they’re not confuse on determining product/brand of feed to be used.
