This is important to the tilapia farmer because during this period, the feed to growth ratio is optimal. compatible combination(s) with poultry, duckery, pig rearing and their different stages till they are harvested. on white crappie growth at similar latitudes as Minnesota. Growth rates of rainbow trout in farms are much higher those that of wild fish, but growth rates in farms also vary with water temperature. Presence of naturally occurring weeds in airbreathing fish culture ponds not only provide protection against poachers, but also encourage the growth of insects which are consumed by the fish. continue for 2 years. Production Although ducks are able to feed upon months, 7 200 kg/ha/8 months and over 10 tonnes/ha/yr have been This curve illustrates the rate of growth. sufficient to adequately fertilize a l ha pond. Goldfish growth rates can be massive for their first few weeks after hatching in a perfect growing environment, as much as a 50% or more increase in body length in a week. As explained elsewhere (Gray, 1928) it is exceedingly dangerous to base a conception of the factors controlling growth on the form of the growth-curve.
