Maintaining water turbidity is essential to some forms of aquaculture. In this class we discuss the different types of turbidity (biological vs. clay) and how to mananage each one. Also discussed are the adavantages and disadvantages of each type. Please check out the link to the SRAC fact sheet on turbidity by John Hargreaves as it provides a good basic overview of this concept!
Issue 2: Dissolved Oxygen, Salinity and Temperature
In this section we will familiarize ourselves with tools used in monitoring oxygen, salinity and temperature. We will use both mechanical and electronic methods, compare the lot and discuss the importance of the relationship between these three water quality issues.
Here we will begin water chemistry. We'll start with basic water requirements and sources, and what can influence them. We'll then proceed to look at each component of "water quality" as it relates to fish. Nitrogenous compounds will be looked at first.
