Description
Technical Field
The invention relates to the technical field of marine organism sample collection, in particular to a coral reef area zooplankton sampling device and method suitable for recipe analysis.
Background
The coral reef ecosystem is a top-level biological community with extremely high biodiversity, is called as a tropical rainforest in the ocean, provides a habitat for 25% of marine fishes by using less than 0.1% of the ocean area, and about 6000-plus 8000 kinds of marine fishes depend on the coral reefs for growth. The ashore coral reef area is a key place for the adult spawning and larva growth and development of most fish populations, and has important significance for fish population resource supplement. Zooplankton becomes an important bait organism for fish larvae due to proper body size and rich nutritional composition, and the ingestion characteristics of zooplankton have great influence on the nutrient supply, fish population size and fishery resource output of fish larvae.
The key for researching the ingestion characteristics of the zooplankton in the near-shore reef area is to obtain a high-fidelity field sample, but the conventional trawl method is easy to cause cod ingestion and zooplankton stimulated defecation, so that the knowledge of the real intestinal contents is reduced, and the requirement for analyzing the ingestion characteristics of the zooplankton in the near-shore reef area cannot be met. Furthermore, the offshore coral reef is generally distributed in shallow water depth (<6m) and has a complex three-dimensional structure, and the coral is easily damaged by the conventional plankton trawl sampling method. Meanwhile, zooplankton in the reef area usually hide in holes of a bottom layer algae mat or a reef disc in the daytime and move out in large quantities at night, and the conventional trawl sampling method is not suitable for night operation in the reef area. At present, the trapping net commonly used for reef area zooplankton survey mostly relies on water flow power for collection, the quantity of collected animals is difficult to guarantee, the standing time is long, and zooplankton entering the trapping net is often stimulated, so that a sample collected by the method is not suitable for intestinal food analysis. Researchers also use the modified water suction pump to suck the zooplankton above the reef area and on the bottom substrate, and the sample collected by the method has large damage to the zooplankton and is also not suitable for analyzing the feeding characteristics of the zooplankton. Therefore, it is urgently needed to develop a sampling device and a method for the zooplankton in the coral reef area, which have small damage and large sample obtaining amount and are suitable for the diet analysis.
