Finding and collating information that already may exist for the lake, river or stream you are interested in, choosing the right sampling methods, and making sure that the data you work hard to collect is stored safely are all important things to consider in your monitoring programme.
There are a range of different sampling methods which can be used, including electric fishing, fyke nets, Gee-Minnow traps, scoop nets, whitebait nets and observation.

Site selection and timing are important factors to consider when designing a representative sampling strategy .

Defining your research questions is the first place to start when designing a survey.
