Biological Responses

Sensitive biological responses to environmental contaminants are useful as early warning signals to predict the damages by long-term exposure. Protocols standardization to quantify biochemical parameters in different fish species is required to validate its use as biomarkers. Comparative studies from different fish species and its interpretation are a challenge for the validation of its use as general biomarkers, representative of environmental impact. In this study, the protocol for liver cytochrome P450 (CYP) analysis from the native Brazilian fish Ancistrus multispinis was established. The microsome contamination by hemoglobin during the analysis of CYP in liver was detected, leading to misinterpretation of the results. The spectrophotometric method for CYP analysis was adapted in order to diminish the hemoglobin interference. Additionally, the western blotting method for CYP1A analysis was tested with success for this fish species.

Reef Fish Species

Oceanic islands and seamounts play an important role on the origin and maintenance of biodiversity, however, these environments are still poorly understood. Here we report 15 new records of reef fish species for the Davis Seamount, Trindade Island and Martin Vaz Archipelago, in the Vitoria-Trindade Chain (VTC). Such isolated sites are among the last frontier for shallow reef exploration in the South Atlantic, and more scientific effort is needed to better understand their biogeography and to help in conservation efforts.

First Time

Data obtained from licenses of spearfishers and surveys conducted in 2004 and 2017 allowed for the analysis, for the first time, of the practice of spearfishing in the Madeira archipelago. Only a small percentage of the population practices spearfishing, mostly local young men. Most of them practice the activity with a partner throughout most of the year and along most of the island's coastal areas, although preferentially along the North and Southeast coast. Results show how, in recent years, despite the population of spearfishers decreasing, the abundance in the annual catch potentially increased, probably due to the higher investment of time in this activity. It has been observed that many fishers complement their catches with manual collecting of invertebrates. Overall, 40 teleost fishes and also 4 crustaceans and 8 molluscs were identified. The most frequently captured fish species were parrotfish and white seabream, while limpets were the most collected invertebrates in both selected periods.
