Course 1: Catch per unit effort data standardisation in R for fisheries biologists and practitioners

course_image

This short course is aimed at introducing researchers to fisheries data analysis using linear models (LM), generalized linear models (GLM) and generalized linear mixed models (GLMM) in the R working environment. Scientific monitoring and artisanal, commercial or recreational fish catch data is often used to assess population status, but such data are usually complex and require careful standardisation.

By the end of the course, participants should be able to:

The sessions during November 23-24, 2022 will be a blend of interactive demonstrations, lectures and Q&A time. All materials delivered during the course - including lecture videos, R scripts and resources - will be freely available on this website for future use and independent learning.

The course GitHub page has a discussion group where you can share your challenges and solutions about R and package installations, statistics or other related topics. You will need a GitHub account to post on this discussion group, but creating a GitHub account is easy and useful anyway.

The course is led by Dr Carl Smith (Nature Research Centre, Lithuania and University of Lodz, Poland) with an extensive expertise in statistical analyses and teaching. The course is organised by Dr Asta Audzijonyte (Nature Research Centre, Lithuania & University of Tasmania, Australia). Additional technical support is provided Dr Catarina Silva (Nature Research Centre) and Dr Eglė Jakubavičiūtė (Nature Research Centre).

Course 2: Further points on exploring, cleaning & filtering data prior to analysis

This auxilary course provides further introduction and discussion about data exploration. This course is not directly related to the CPUE standardisation course above and can be done with or without completing the previous course. The data exploration course has been prepared and contributed by Dr Harry Gorfine, fisheries biologist at Nature Research Centre, Lithuania and Victorian Fisheries Authority, Australia. The course provides a general overview of data exploration challenges and good practices and is intended to be followed independently.
