Lighting adjustment and control method capable of promoting surviving, growth and development of young fish of fugu rubripes

Abstract

The invention discloses a lighting adjustment and control method capable of promoting surviving, growth and development of young fish of fugu rubripes, and belongs to the technical field of aquaculture. According to requirements of the fugu rubripes at the stage of young fish for light spectrum and light intensity, light environment can be adjusted and controlled for the stage of young fish, and in an early development stage of the fugu rubripes, the light spectrum and light intensity can be adjusted and controlled, so that the light environment of the fugu rubripes can be improved, the growthand development situation of the young fish of the fugu rubripes can be promoted, and further the productivity level and the economic benefits of breeding enterprises can be increased. The lighting system used by the lighting adjustment and control method comprises a single light spectrum LED light source and a controller for adjusting light intensity.

Description

technical field [0001] The invention belongs to the technical field of industrial farming, and in particular relates to a light regulation method for promoting the survival, growth and development of puffer puffer juveniles. Background technique [0002] External environmental conditions have a huge impact on the growth and development of fish. As an important and complex ecological environment factor, light can be roughly divided into three elements, namely, light intensity, spectral composition and light cycle. These three important light factors play different roles in the growth and development of animals. At the same time, the three have a synergistic effect, which directly or indirectly has an important impact on the feeding behavior, growth and development, and survival rate of fish. In the breeding process, the growth and development of different species of fish require different light conditions. [0003] The physiological and behavioral characteristics of most ma...

Problems solved by technology

With the continuous breakthrough of the artificial breeding technology of red-finned puffer in China, its breeding scale in China is getting larger and larger, but the survival rate of juvenile red-finned puffer in artificial facilities is currently low, and its production is greatly affected , the main factors include the aggressive behavior of the fish school itself, unreasonable environmental conditions (temperature, light, water quality, etc.), epidemic diseases, etc.

There are relatively few scientific studies on the effect of light on pufferfish, resulting in no theoretical basis for the regulation of light environment in the current facility breeding process.

There is a lack of research and technical application on the influence of spectral environment on its growth, development and physiology. Therefore, designing a reasonable spectral environment is of great significance for improving the survival rate of puffer juveniles and promoting their growth and development.
