|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.
