Weight determined by dividing number of 1.Yr fish by number of 1-Yr fish per pound (51 fisMb for 1-Yr razorbacks) <br />from Table 4 In Wydoskl (1994a). <br />4. Acre estimate made using assumption of 500 lbs. offish (up to 3.5 In.) per surface acre of pond (Wydoski 1994a). <br />5. Total surface area for ponds needed is 25% more than the area of active ponds for cleaning, sorting fish, etc. (Wydoski 1994a) <br /> <br />Q <br />Q <br />N <br />00 <br />N <br />c::> <br /> <br />Razorback Sucbr.
