Abstract

The evaluation of mussel loss rate caused by marine disasters is a new scientific proposition produced by the intersection of marine science and fishery science. At the same time, it is also a difficult problem in fishery economics and insurance value accounting. The effect of sea wave disaster on mussel loss rate was studied in this research, adopting the third generation wave model SWAN to calculate the significant wave height. The significant wave height with different return periods around Shengsi sea area was calculated, and the relationship between mussel loss rate and significant wave height in Shengsi sea area was analyzed. The results show that when the effective wave height is up to 3 meters, mussel begin to fall off; when the effective wave height is bigger than 9 meters, the probability of mussel loss rate reaching 100% is high.

Key words

mussel / SWAN / significant wave height return period / loss rate
