Equipments/Tools and Shrimp Sampling Stages

Like already on explained before, as generally shrimp sampling could be difference as (1)Fry sampling, (2) Sampling of ancho, and (3) Sampling of jala. Before discussion about equipments/tools and stages of sampling, there are several logical basic that need to be attention before implemented sampling, there are :

Sampling activity more better to be implemented at the sun's rays not too extreme or in the other word on calm/shade condition (morning/afternoon time, or a shelter placed from the sun's rays). Purpose of this condition is to avoid decreased shrimp quaility cause of extreme sun's rays, in spite of the shrimp sample numbers not too much.
Sampling activity more better to be implemented at the condition of shrimps as generally is normal and not on 'moulting' condition, because a shrimp on the moulting condition is weak and susceptible for unstable envirement.
Sampling activity more better to be implemented about 2 - 3 hours after feeding, with the result that more effectively, because the shrimps still on feeding area and so still on range of jala. Whereas for sampling of ancho, that time ranges ias the time for shrimps to start 'invading' ancho in order to consume food on ancho.
Sampling activity more better to be implemented not on water circulation condition and minimalized waterwheel operation, with result that opening of jala not disturbed by impact of water current.

Especially for incidentally sampling, there are on pond with shrimps that indicated trouble/disease, sampling could be implemented as soon as without attentions above, this condition is for can detecting and it decision making in line with shrimp culture treatment or harvest decicion

Fry Sampling

Like on explained before, that the purpose of fry sampling is more direction for count estimation/fry population, also fry condition/quality that will be cultured.

Equipments/Tools

Place of sampling (like a bucket) with 2 (two)various are one for place of fry that will be sampling and other one for place of fry that have beev sampling. The place that to be used is more better have clear color with the result at the moment of fry to be placed on it will seem contrast and not disturbing of fry condition monitoring although fry population counting.
Count equipment like calculator or others. Calculator is to be need to count fry total numbers, while other count equipment is to be functioned for making mark of counting multiplied. As note : in connection with that fry counting is manually and one by one, then for reminding the number that have been counted easily, commonly for each multiplied will marked with other count equipment (usually it using a palm leaf rib or stick matches or depend on it ordinary).
Writing kit for documentation of fries number and fry condition monitoring.

Fry Sampling Stages

Fry sampling could be implemented at fries procurement moment in hatchery also at moment that the fries will be culture, but as principal that stage which need to be implemented are:

Make monitoring on general condition/quality of fries with visual monitoring. If fries placed on palstic bags, monitoring can be done by taking up and see under lights, until condition/quality of fries can be monitored with clear.
Put some plastic bags that will be used on sampling.
Moved the fries on the plastic bag along with it water to bucket that has prepared with slowly and keep quietly at a moments.
Make visual monitoring to condition/quality of fries then continued with fries quality test on the bucket. The test of fries quality can be done by simply and practically, there are : (i) making curent water rotation on the bucket, this treatment is to know activity level and direct of fry swimming, (ii) give a shock on water with fingers, this treatment is to know fries reaction level toward stimulation of movement that to be given, (iii)Place one finger on the water at a moment, this treatment is to know fries reaction level to stimulation of smelt and food.
Start counting number of fries manually using tool like spoon that it medium/big size. in connection with that fry counting is manually and one by one, then for reminding the number that have been counted easily, is more better that each multiplied will marked with other count equipment that has prepared.
Prepare the other bucket that contained water (more better water from the same plastic bag, until its not become fry shocking that caused of water condition difference as extremely) as place for fry that have been counted and monitored.
After fries number counting finished, count fries total number on one plastic backet. If fry sampling is done at hatchery, then the fries that have been sampling, its be returned at a first condition.
While if sampling is done at pond area, then the fries on the bucket together wit other fries that still on plastic bags as soon as to be placed on shrimp culture area to get aclimatitation pocess.
