Abstract

The invention relates to an online detection and identification method and system for a fish toxic red tide algae. The method comprises the following steps: acquiring three-dimensional fluorescence spectrum data of a red tide algae sample; preprocessing the three-dimensional fluorescence spectrum data of the red tide algae sample; extracting spectral features from the preprocessed three-dimensional fluorescence spectrum data; according to the extracted spectral features, establishing a mapping model of fish toxic red tide algae hemolytic activity identification by adopting a particle swarm optimization support vector machine method; and determining an identification result by using the mapping model according to the extracted spectral features. The online detection and identification method and system for the fish toxic red tide algae provided by the invention can realize uninterrupted in-situ online detection and improve detection precision.

Description

technical field [0001] The invention relates to the field of qualitative detection of fish-toxic red tide algae, in particular to an online detection and identification method and system for fish-toxic red tide algae. Background technique [0002] Harmful algal bloom (HAB), also known as red tide, is a harmful ecological phenomenon in which some phytoplankton, protozoa or bacteria explosively multiply or highly gather in seawater under certain environmental conditions, causing water discoloration. Among them, Ichthyotoxic red tide can produce a variety of toxic substances, causing a large number of fish and shellfish to die in a short period of time. At present, fish-toxic red tide algae have been widely distributed in the coastal areas of China. In 2012 alone, the East China Sea lost more than 2 billion yuan due to Karenia militaris, which seriously restricted the sustainable and healthy development of China's offshore aquaculture industry. The in-situ and online early rap...
