Description

Technical Field

[0001] The present invention relates to the technical field of fish egg collection equipment, and particularly relates to a fish egg collection stretcher. Background Art

[0002] Trachinotus ovatus, also known as pompano, belongs to the genus Trachinotus of the family Carangidae in the order Perciformes, and is a warm-water pelagic migratory fish. The main farming methods include seawater pond farming and seawater cage farming. The farming techniques include broodstock cultivation, artificial induced spawning and fertilization, hatching, and seedling cultivation, etc.

[0003] In recent years, with the improvement of artificial breeding and farming techniques, the aquaculture production of Trachinotus ovatus has also increased year by year, which has also brought a series of aquaculture problems: (1) Since pompano has well-developed muscle tissues, the stress response during artificial egg collection is relatively large, and intense movements can cause muscle strains or surface injuries, affecting the health and recovery of the fish body; (2) The fish body is out of the water environment for too long during egg collection, resulting in symptoms such as dehydration and hypoxia; (3) The intense movement of the fish body makes the egg collection process difficult, increasing the operation time and complexity; (4) The dorsal fin of pompano has hard spines, and the intense reaction of the fish body poses a safety risk to the operators. Therefore, there is an urgent need to develop an egg collection device that can reduce the life danger of fish during egg collection, reduce fish body surface injuries, and is more convenient to operate.
