Shrimp Feeding Program
Basically, shrimp feeding program is a method of feeding to shrimp at a shrimp culture cycle period. This program also establish successfully level of spread all over shrimp culture especially related with cost production level. Based on this matter, shrimp feeding program arrangement is need accurately and exactly on determine shrimp need level to feed.
Several factors that need to be noticed on arrangement of shrimp feeding program mainly include : (i) kind of feed, (ii) feed size, (iii) feed quantity/weight, and (iv) feeding frequency.
One of standard that used to measure effectiveness and efficiency level of feeding program is Food Conversion Ratio (FCR) that is an equivalency between cumulative weights of feed that already given with shrimp biomass at specific time. As example: at a pond have already harvested with biomass = 1 (one) ton, while total weights of feed that already given is 2 (two) tons, so the FCR value = 2.
The standard value of FCR that many used to determine effectiveness and efficiency level of feeding program for intensive shrimp culture is FCR value between 1.8 – 2.5. With FCR value, we can estimate production cost for shrimp feed as well as sale price value at that time. The development of FCR value is need monitored at every conducted sampling of population and biomass periodically within one cycle of shrimp culture.
As illustration about feeding program can viewed on Example of Feeding Program. In order to make easier to understanding that illustration above, here it will explained several terminologies on that illustration:
In the other hand, if shrimps appearance at water surface or at ancho more much than ordinary, so it can made as an indicator that natural feed stock within water have already decreased or empty. This condition happen because the shrimps will try to look for a feed that its seldom to be found at pond water bottom, then at condition like this the shrimps usually to convoy activity at around pond boundary or too many appear at pond wall.

- PL = Post Larva, this term is to show a shrimp’s age and usually it’s expressed on age day. This variable is very important because shrimp need level to feed is always changes based on age increase .
- ABW = Average Body Weight, this term is to show a shrimp’s average weight within pond at specific time. This variable can obtained through biomass sampling periodically..
- SR = Survival Rate, this term is to show a shrimp’s survival level within pond at the specific time equalized with early fry density. This variable can obtained through population sampling periodically.
- Crumble, this term is to show a kind of artificial feed with powder size to granule size.
- Pellet, this term is to show a kind of artificial feed size with pellet size (small, medium, and big size).
- Number of Feed (with specific coding), this term is to show a size of feed pellet. This number coding can be different between each shrimp feed companies
- Blind Feeding, this term is to show a feeding activity without attention of feeding program and it’s implementation is depend on natural feed stock within pond water and usually it implemented at fry stage. The objective of blind feeding is to acquaint artificial feed to fry and to anticipate decreased natural feed within pond.
In the other hand, if shrimps appearance at water surface or at ancho more much than ordinary, so it can made as an indicator that natural feed stock within water have already decreased or empty. This condition happen because the shrimps will try to look for a feed that its seldom to be found at pond water bottom, then at condition like this the shrimps usually to convoy activity at around pond boundary or too many appear at pond wall.
