The TX-52 is in a food-grade setting and NCI re-serves the right to disallow the use of nonfood-grade materials.
In case of feeding too small pellets than the suitable size, more energy has to be used by the cultured animal during searching & eating more pellets that result in inefficient feeding. On the other hand, pellets that are too large will depress feeding & may cause choking in severe cases. Materials and methods in Aquafeed Formulation:

The pellet with the largest pores adsorbed the highest amount of oil but also resulted in the highest oil leakage. Determining the maximum amount of tunicate meal. By running a mixed design experiment in the statistics program, he has set some quality requirements for the pellet when adding tunicate meal to the feed.
I. Introduction of Aquafeed . Aquafeed pellet is made of amount of ingredients in various proportion that are pelleted or extruded to the compound diet, which have good shapes, full gelatinization and high level of protein. According to their buoyancy, fish feed can also be divided into sinking, slow sinking and floating aquafeed.
