The Science of Sustainability

Sustainability in the Ocean.

For my Science project I have been investigating sustainable fishing. I had to do an experiment which simulated rod and net fishing, using beads to represent 2 species of fish, the Orange Roughy (an endangered species which breeds slowly) and Salmon ( a faster breeding species). I found rod fishing was more sustainable as it allowed time for populations to build up between "seasons", represented by 20 second fishing periods. Net fishing is far less sustainable than rod fishing as large numbers were caught easily in one "season".

This made me aware that regulations that are in place from government authorities eg NSW Department of Primary Industries, must be strictly regulated and strictly adhered to. This will ensure sustainability of species in our oceans and waterways.
