Crescimento comparativo de dois mexilhões cultivados em manguezais de macromarés da Amazônia
[摘要] The present study evaluated the growth of the species Mytella guyanensis and Mytella strigata on ropes suspended in Amazon Macrotidal Mangrove Coast. The mussels were farmed at a density of 840 ind. m-10.05). The daily growth rate was greater for M. guyanensis than for M. strigata. At the end of the cultivation cycle, only 451 ± 46 (59.9%) of M. guyanensis individuals reached commercial size per meter of rope compared to 670 ± 73 (89.3%) of M. strigata individuals. Survival rates were similar. Salinity and temperature increased progressively throughout the experiment with the reduction in rainfall and were within the range considered ideal for these species. In conclusion, the farming of both species of mussels was viable under estuarine conditions influenced by macrotides, with satisfactory survival rates and daily growth (shell height and weight).
