Especially in the aquaculture industry that involves a group of community. Thank you.
You could try using enterprise budgets to compare the profitability of the new technique with the old one. This method allows you to compare yields, costs, and/or profits to decide which is more effective. Good luck!
Hi Bayu - I agree with Yaw Boamah Ansah's comment above. My group did an analysis of a feeding method that improves the efficiency of tilapia production by reducing cost and encouraging foraging (attached). We conducted a controlled study on 9 commercial farms followed by a marginal economic analysis to compare operating costs (feeds, labor) and product value. I needed the help of an economist and a statistician for this paper. This compares the economic effectiveness of variable techniques but other factors like environmental impact might need to be considered.
Bayu, Another method if you are looking at a wider range of environmental variables, you might try is life cycle analysis (LCA). For a review of LCA use in aquaculture see:

Thank you very much for your kind suggestion Yaw Boamah Ansah, Christopher Brown and Michael Pietrak. The new techniques adopted by lobster seed collectors (fishers) have made a dramatic increase of production. There is always pros and cons in this change in terms of economic benefits and environmental harms.
In Arkansas we have a system for this. It is called a verification program. Farmers who would like to try new farming practices contact our extension agents. These people go to the farm and help with new methods and installments. They also record and analyse data from the farm. In this way we can compare the new practices to traditional ones on other farms and to the past performance of the farm making the changes.
It requires a lot of cooperation from the farmers, but is worth doing.
New feeding method is important for new species taken for culture. Every animal has its own feeding times that should be followed to avoid waste of feed. By studying biological Rhythm the feeding time can be fixed for aquaculture practices.
the direct judgement criterion is your could get a satisfying culture results, so the farmers could get high profit from aquaculture.
