STUDY OF THE BEHAVIOR OF DIFFERENT SOWING DENSITIES OF DEADS FOR THE RAINBOW TROUT FAT
The behavior of different planting densities of dedinios (40, 60, 80 and 100 fish / m2) was studied for the fattening of Rainbow trout (Oncorhynchus mykiss); the fish used were 840 dedinios of 4 months of age and with an average weight of 24.20 gr; and an average size of 2.92 cm in total body length...

| Summary: | The behavior of different planting densities of dedinios (40, 60, 80 and 100 fish / m2) was studied for the fattening of Rainbow trout (Oncorhynchus mykiss); the fish used were 840 dedinios of 4 months of age and with an average weight of 24.20 gr; and an average size of 2.92 cm in total body length; the same ones that were distributed in a completely randomized block design with three replications per treatment, having a total of 12 experimental units. The average weights at the beginning of the investigation were 24.20 gr and after 7 months they were 253.75 gr. While the total food consumption was 316.81 gr during the 7 months of evaluation. At the same time the fish gained 229.55 grams in total. Trout were good food converters since they required between 1.11 and 1.71 kilos of balanced to convert one kilo of meat. Regarding height, there were no significant statistical differences in the treatments, starting with 12.92 cm and finally reaching a total body length of 26.95 cm in the last evaluation (seventh month). |
