Shrimp Sampling 03

Sampling of Ancho

Interpretation of ancho have been distincted on explaining before, it’s a tool/equipment that used to control feeding program, growth and quality of shrimps as daily/incidentally. In generally, ancho dimention is square form with measure 1 m x 1 m and it frame made from wood/steel and completted with streameen (like jute from nylon)) and in it central be given sinker in order to can reach out at the bottom of waters.

Equipments

1. Ancho that one of a part of shrimp culture tool. Viewed base on sampling equipment, the function of ancho is to be use for taking shrimp samples


2. Plastic bucket that contained water as place of collected shrimp samples from several ancho
   
   
3. Small plastic bucket/water dipper as place of shrimp that will be monitored of it condition and be measured of it average body weight.
   
   
4. Weight measure equipment ('sit' model) with 1 kg capacity as tool for measuring shrimp average body weigth
   
   
5. Calculator for calculated average body weigth.
   
   
6. Writing kits for documentation of shrimp number and average body weight calculating results and others.
   

Sampling Stages

1. Preparing all equipments that to be need like mentioned above in order to sampling process can be implemented with effective.
   
   
2. Lifting up ancho from water bottom with slowly in order to that the shrimps not jump to come out from ancho (this condition is purpose in order to the number of shrimps that could be take is maximally, with the result that it can representated condition and population of shrimps on pond mentioned.
   
   
3. Put all shrimps from ancho and place on bracket that contained water, continue this process for other ancho that pond own and collected at the same brucket.
   
   
4. After the process above finished, then collect the shrimps on small brucket/water dipper to measure total weight from shrimp samples.
   
   
5. Take litlle bucket/water dipper that contained shrim sampleson weight measure tool ('sit' model)(make sure that tool on normal condition).
   
   
6. Measure and record total weight of shrimp samples based on weight measure tool.
   
   
7. Measure weight of plastic bucket that contained water in order to know the real total weight of shrimp samples with this manner:result weight of item 6) above minus weight of item 7). For example if weight of item 6) = 500 grs, and weight of item 7) = 250 grs, then real total weight of shrimp samples = 500 grs - 250 grs = 250 grs.
   
   
8. Count total number of shrimp on that buckets and at the same time monitoring in line with condition/quality of shrimp. If fined shrimp with trouble indication, record the problem as decision making matters related with shrimp culture technically or other aspects. The shrimps that have been counting as soon as get back on pond water in order to avoid decreased shrimp samples quality.
   
   
9. Count average body weigth (ABW) with formula : shrimp total weight devide shrimp total number. Example : if shrimp total weight = 250 grs, shrimp total number = 100 pcs, then ABW = 250 grs : 100 pcs = 2.5 grs/pcs.
   
   
10. Record calculated and monitored results base of decision making process.
    

Notes

• Sampling ancho process is better to be implemented about 2.5 - 3 hours after feeding in ordr to the shrimp numbers that will be take can maximally.
  


• Sampling ancho process is better to be implemented as fastly in order to decreasing quality of shrimp samples.
