Evaluation of caridean ecological distribution in the Ubatuba region, southeastern Brazilian coast using unsupervised machine learning technique

Abstract

Several human actions can directly or indirectly affect marine environments (O'Hara et al., 2019). Among the anthropic impacts, we highlight bottom-trawling fishery, which is considered one of the main sources of environment perturbation in marine ecosystems (Fransozo et al., 2016;Simpson & Watling, 2006). The northern coast of São Paulo State (Brazil) is highly important for shrimp fishery due to the high abundance of Penaeidean shrimps. Thus, the low selectivity of fishing devices captures several non-target species, known
