Experiment is the main tool of a researcher. The effect of factors or treatments can be assessed only by testing them experimentally. Several factors like composition of stock, density of stock, feeding level, depth of water and salinity come into play in aquaculture experiments. Sometimes the problem may be one of developing a low-cost technology which can be gainfully employed by small and marginal farmers. Here again a number of factors under study act and interact. The main difficulty in such situations is that effects of extraneous factors very often mask the real treatment effect. One way to overcome this difficulty is to use homogeneous experimental material. However there are very many practical limitations to achieve such an end. A statically planned experiment attempts to minimise effects of heterogeneity in experimental units from treatment comparison, reduce experimental error, provide unbiased estimates and ensure validity of test of significance. The paper discusses at length the various statistical requirements in experimentation with special reference to coastal aquaculture systems.
