I haven't studied compensatory growth in HSB but have looked into it with TP. Whether the compensatory growth is an advantage economically depends on a lot of factors. From what I have seen this mainly has application in keeping fish (like fingerlings) in high density for later use. One has to consider time and what its value is as well as factors like fish size at the end of grow out. For TP, I have yet to read a study that establishes equivalent or better end of grow out weights. The lower cost of feeding is kind of duh, if you starve a fish, yes you are saving some money in feed but there is a corresponding loss of weight and the effect of compensatory gain and lower FCR declines with time. From what I have seen with TP, one may not bank on larger more marketable fish at the end of grow out by doing this. But the practice can help to lower the cost of overwintering high densities of fingerlings and in cases where they are sold by weight (as opposed by the head) compensatory growth has high economic incentive leading into sale.
