Issue 1:  Turbidity

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.

Issue 3: Ammonia

 

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.

 Issue 4: Alkalinity, Hardness and pH

 

Alkalinity, Hardness of water and ph go hand in hand.  We will look at each one individually and then focus on how they work together, or in some cases against each other to alter water quality.

 Issue 5: Phytoplankton 

Phytoplankton is the primary food for many marine and aquatic organisms.  They also provide much needed oxgyen and nutrient cycling to the ecosystem in which these animals live and thrive.  By studying phytoplankton life cycles and cultures we will be able to improve larval fish survival and manage pond water chemistry better.

 Issue 6: Zooplankton 

Phytoplankton is the primary food for many marine and aquatic organisms.  They also provide much needed oxgyen and nutrient cycling to the ecosystem in which these animals live and thrive.  By studying phytoplankton life cycles and cultures we will be able to improve larval fish survival and manage pond water chemistry better.
