Data Set D03 Quantifying the effect of fishing on Amazonian fish
Research questions 1. How stable are the size distributions of the oscar, A. ocellatus, and white piranha, S. rhombeus, in the Samiria River, given constant fishing quotas and a drought in 2010?

2. Would you recommend adjusting the fishing quota for either species?

Summary A study carried out on a tributary of the Amazon River which looked at fish stocks for 2 species of fish (an Oscar and a Piranha) over a five year period. The study looks for evidence of change in population number and structure and relates these to the fishing activities of local communities and the possible effects of a severe drought in 2010. Analysis uses class interval or bin widths to compare the fish populations. The study provides a good opportunity to discuss sustainability of fish stocks in delicate ecosystems such as the Amazon river and provoke further thoughts about current threats such as climate disruption/change. For those keen to practice statistics, the data would be very suitable for further statistical treatment in order to determine degrees of significance over time.
