1. Careful and thoughtful: the principle is that the release site should be sparsely populated, with a wide area and deep water, suitable for species survival.
2, not fixed: not fixed time and place to buy, not fixed time and place to release, in short, in order to avoid interested parties to take this opportunity to collect money and capture biological species that harm the release.
3. Scientific release: With the development of social progress, profound changes have taken place in the social environment, ecological environment and human environment. Any arbitrary release may have adverse consequences. As a religious ceremony, release should also keep pace with the times, and the way, place and type of release should be considered comprehensively. Only in this way can we achieve sustainable development.
4. Ecological release: With the increase of population, the acceleration of industrialization and the deterioration of ecological environment, the environment on which human beings depend is becoming more and more fragile. In recent years, release as a way of education has become more and more popular. Therefore, releasers or charities need to coordinate with local forestry, fishery administration, river courses and other relevant departments before releasing them, so as not to release exotic species that will harm the local environment, and strive to make releasing such things with boundless merits not become "harmful". Crayfish breed quickly, and the number and place of release should be reasonably selected.
