| An experimental culture trial of juveniles of mutton snapper Lutjanus analis was conducted in order to evaluate the growth potential of the species and its adaptability to culture conditions. The juveniles (N = 127) with an initial weight ranging between 125 and 178 g were held at a stocking density of 15.9 fish/m3 in a floating cage and fed on a commercial artificial diet of 45% protein for a period of 1 to 8 days. Results showed an individual daily weight increase of 3.16 g/ day and a specific growth rate of t .06 %/ day. Although, the food conversion ratio obtained with the artificial diet was high and inadequate (TCA = 3.53). During the culture period all fish showed great tolerance to handling stress and to water quality conditions in the cage (O2 =... |

| An experimental culture trial of wild juveniles of jewfish Epinephelus itajara was conducted in two different places in the north coast of Colombia in order to evaluate the growth rate of the species and its tolerance to captivity conditions. Two different groups of fish were evaluated in each place, one fed on an artificial diet and the other on trash fish. All fish were held in floating cages for periods ranging from 63 to 89 days. Results showed excellent individual daily weight increase (6,83 and 12,4 g/day) and specific growth rate (1,4 y 0,96 %/day) for fish fed on trash fish in both places but conversion ratio was too high and inadequate (9,01 and 9,97). Trials with the artificial diet gave negative results because the fish didn’t accept the pellets... |
