Shrimp Culture Management at First Month Phase 03 – Feeding Management

Viewed from finance aspect, shrimp feed (especially on intensive shrimp farming) is an importance factor because it becoming the biggest contributor in the case of production cost. Feeding program which it is not compiled carefully to following shrimp need level can lessen an advantage level that to be obtained in one period of shrimp culture. In a normal condition, shrimp need to feed will progressively mount, so that arrangement of feeding program needed to conduct since fry disperse till the shrimp have been assumed competent to be harvested normally.

Shrimp feeding management at first month phase as early from a feeding program at a shrimp culture, is very determined by availability natural feed in pond water. Availability of natural feed is very influenced by process preparation of the disperse land that conducted before fry disperse process. If natural feed for shrimp within pond water available in abundance enough, hence artificial feeding for shrimp at this phase relative tardy. On the contrary if availability of natural feed within pond water very few, hence artificial feeding has to soon implement. Marginally, shrimp feeding management at first month phase is like explanation hereunder.

1. Early time till second week sub-phase, at this sub-phase natural feed is main feed source for fry/small shrimp. Natural feed availability within pond water factor will very determine when the artificial feeds start to given to shrimp. Explanation related natural feed have been discussed under consideration before.
   
   A needed matter to do is monitoring to behavior and appearing of small shrimp in pond water as indicator of shrimp need to feed which its supply from outside, if availability of natural feed within pond water have fallen short requirement of shrimp population. Toward this condition the shrimp usually will do convoy within pond water in order to look for other feed, because within the pond water natural feed have fallen short for shrimp population any more.
   
   In order to anticipate condition of lack of natural feed availability for shrimp at the selected time, hence at mid of second week sub-phase better have started to be conducted artificial feeding in “crumble” size with “blind feeding” system. “Blind feeding” program can be interpreted as a feeding method to shrimp without paying attention to quantity/weight of feed and its frequency. The main objective of “blind feeding” is to defining artificial feed to fry/small shrimps, so if at selected time the natural feed within pond water have fallen short, be expected fry/small shrimps have accustomed to that artificial feed.
   
   
2. Third week till fourth week sub-phase, usually small shrimp have recognized artificial feed through “blind feeding” program which conducted at sub-phase before. Quantity/weight of feed and feed size which is passed at the moment have started measured with daily feeding frequency 2 – 5 times depended from shrimp condition.
   
   At this sub-phase, management of shrimp feed is better have good programmed in line with growth, condition of and need of shrimp at the selected time. In order to know effectively and according to early feeding program which have been applied hence at the end of fourth week sub-phase better be conducted a shrimp sampling to measure the shrimp average body weight, condition and quality of shrimp and also to predict density level of shrimp population. Pursuant to the sampling result, hereinafter feeding program is need rearranged pursuant to estimation which has been made.

Based on discussion above mentioned hence needed matter to give attention to first month phase is a period of transition for shrimp from natural feed to artificial feed. A period of the transition in shrimp culture cycle is relative differ among a period with other periods, so carefully monitoring factor to behavior and appear of small shrimp within pond water require to be conducted.

The detailed discussion concerning with shrimp feeding program at a shrimp culture period have been elaborated in before explanation.
