Fish sampling

In week 3 we did some fish sampling. We used the a seine in Guana River and Guana Lake during high tide and analyzed, measured, and released the organisms that we caught. We caught several organisms in both areas, these included anchovies, flounders, trouts, shrimp, crabs, and more.
The guys did a great job at pulling the huge seine though the water, it did not look easy.

 

 When the seine was pulled in we worked fast to make sure we kept mortalities low and so we would not stress the fish. We handled them carefully and when we were done recording they were released. This data, along with water quality information collected that day too, allowed us to get a picture of the distribution of organisms and how disturbances can affect this. That day the tide was high and there were a lot of fishermen on site.
