Abstract: The objective of this paper was to provide useful advices for optimizing industrial distribution, promoting the utilization of patent and leading industry innovation. This paper took Chinese Academy of Fishery Sciences as an example and used quantitative analysis to elaborate the time distribution of the fishery patent, research on the IPC classification, theme words, the top ten fishery research fields and percentage of valid patent. The results showed that the developing process could be divided into three periods which were slowly, fast and fluctuated developing period, respectively. Most patents were related to traditional aquaculture technics such as feed processing and breeding or traditional fishery technics such as offshore cage. But patents related to industrial aquaculture were not much. Besides, fishery patent authorization rate was higher than the overall patent authorization rate in China. But the technology transformation of the granted patent was not optimistic, maintaining time of valid patent was short and technic exportation was insufficient.
