1. Introduction
Harmful effects attributed to aquaculture practices are of foremost concern to the industry and are subject to increased public awareness (Sapkota et al., 2008; Subasinghe et al., 2009). Often, these harmful effects are related to the environmental impact of aquaculture activities, among those: (1) destruction of natural sites such as wetlands and mangroves, (2) spread of diseases, (3) decreased biodiversity of natural fish populations by escape of nonnative fish species, and (4) pollution of ground and surface waters by effluent discharge (Boyd, 2003).
