Estimating size at first maturity (L50) from Gonadossomatic Index (GSI) data

Neotropical Ichthyology
Correct estimates of size at first maturity (L50) are useful for fish stock management and different methods have been proposed. In this study we propose the use of a modified logistic to estimate L50, including a variable asymptote (A). We also test the

Influência de um cultivo de camarão sobre o metabolismo bêntico e a qualidade da água Influence of shrimp cultivation on the benthic metabolism and water quality

Revista Brasileira de Engenharia Agrícola e Ambiental, 2008
Atividades de cultivo de camarão tendem a aumentar a taxa de sedimentação de matéria orgânica nos corpos hídricos receptores de seus efluentes, devido à excessiva produção de produtos de excreção e sobras de ração.
