Noninvasive enhancement and release rescue technique

Abstract

The invention discloses a noninvasive enhancement and release rescue technique which includes the steps: first, placing high-quality aquatic animal fries and fingerlings into anti-flow velocity ecological conservation release equipment, and performing drug rehabilitation therapy and natural water simulated adaptation training in a natural water area to be released; second, placing rehabilitated fries and fingerlings into the equipment for conservation (breeding), performing comprehensive adjustment such as improvement of specifications, physical abilities, disease resistance and wild-exercising return adaptability and making first-phase preparations before enhancement and release; third, performing non-contact and noninvasive direct release under the combined action of an automatic liftingdevice and a release device system on the equipment at any time when detecting that the fries and fingerlings meet release conditions. The high-quality aquatic animal fries and fingerlings are artificially bred fries and fingerlings for a scientific research institution. Safe and controllable enhancement and release rescue can be performed in a natural complex water area environment, an experimental platform can be provided for the scientific research institution, cost can be saved, and the comprehensive efficiency of enhancement and release rescue can be improved.

Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to a non-damage multiplication and release rescue technology. Background technique

[0002] The so-called multiplication and release is the activity of artificially releasing aquatic biological seedlings or broodstock to public waters such as oceans, rivers, and lakes to increase the amount of water resources and restore their natural populations. An effective measure to promote the ecological environment of waters and promote the sustainable development of fishery.

[0003] At present, due to the impact of human activities such as damming of rivers, water pollution, waterway regulation, and bank slope hardening, the diversity of aquatic organisms continues to decline, and the task of restoring water forms is arduous. According to the requirements of the State Council and the Ministry of Agriculture, the method of multiplication and release is adopted to rapidly replenish aquat...
