The relationship of fishing regulation areas of tidal waters around BC Vancouver and water transparency

Abstract

BC government zone tidal water into different Areas and sub-areas and implements different fishing regulation to coordinate and protect the ecological environment. Fishing Regulation studies on the population structure and life history of Roman Chrysoblephus laticepsshowed (Gotz, 2008) that Chrysoblephus laticeps in protected areas had a relatively higher population density and average size than those in non-protected areas which is considered to be due to higher reproductive opportunities and less boat disturbance due to less hunting frequency. Therefore, we suggest that BC government's fishing regulations for different areas will have different effects on fish density in the water body.Moreover, research in 2010 showed a direct relationship between water transparency and population density of Oreochromis niloticus, a tilapia in Northeast Brazil (Menezes, 2010). Water transparency shows how easy the light can pass through water which ideally indicate the turbidity of the water (Yentsch, 2002). The higher tilapia population density directly reduced the biomass of microorganisms and diatoms in the water which directly affects the oxygen content of water, the fixation of suspended particles and the degradation of organic matter, resulted in the reduction of water. Thus, we aim that the sub-areas executed with different fishing regulations may have different impacts on water transparency of different Areas.

This study reports a research on water transparency in different waters sub-areas in Vancouver. In this study, an experiment which has two parts will be completed. The first part of the experiment is using a tool called secchidisk to measure water’s transparency. The second part of the experiment is using some indicators like turbid liquid to measure the concentration of the algae and suspended matter to get the transparency of water indirectly. The result of the study can provide advice on environmental protection and fishing policies.
