Adding more on research design and data collection

As the same as previous trips, this one was very busy with works have to do such as checking logbook recording, sampling, papers, stamps ... More than that this time I have to find location to catch fish and shrimp in the forest, design catching gears, getting people to assist, looking for more places for sampling the catch from shoreline to inland, and many others....

First, look at the picture, drink with people in Nam Can


And then this picture, drink with border guards


Some exercise at border guard base


But please don’t think I just go there for drink :), just some social activities to make works run smooth.

Marking new places in deep forest for catching fish/shrimp species which entering in to the mangrove, there ware 8 places at to sites were selected which these follow species are dominant: Rhizophora, Avcenia marina, Ceriops decandra, and planted Rizophora


A border guard took me in to mangrove


The catching gear looks like this:


The gear has two wings, height 2m, and length 10m, mesh size 1mm. The gear will be put in to the forest, facing with water flow direction when the tide goes down. Fish and shrimp moving along the net and get in trap in the middle of the gear.

The idea of making a quadrad is not possible because after discuss with fishermen, they said that will be not work with quadrad design. When tide goes up above the net, if there are fish and shrimp inside they will try to escape and we will catch nothing.

Good news just got from fishermen, the traps caught quite a lot of small fish and shrimp in the forest. They start classifying the catch and record. Good, will back on this later.
