Problems solved by technology

[0003] In the construction of fishways, it is necessary to build a rest pool for fish to rest during their ascent. The shape of the rest pool may affect the use efficiency of the fishway. If the fish prefer a rest pool with a certain shape, it will be beneficial to continue their ascent after rest; if not Get enough rest and continue to ascend, which may cause the ascent to fail

example 1

[0024] Example 1. Spatial selection experiment of crucian carp

[0025] 1. Select 20 crucian carp from the same source, with similar age and size, body length 10-20cm, and carry out experiments on individuals and groups.

[0026] 2. Put the crucian carp into the central cylinder 1, and after 5 days of adaptation, start feeding the same amount of the crucian carp's favorite bait in containers of various shapes, which is convenient for long-term experimental observation.

[0027] 3. The distribution of crucian carp during the day and night was continuously photographed and recorded with an infrared camera, and the continuous observation time was 10 days.

[0028] 4. Record the distribution of crucian carp at 9:00, 12:00, and 20:00 every day, and the one with the highest distribution probability in a container of a certain shape indicates the preference for that shape.

example 2

[0029] Example 2. Spatial selection experiment of grass carp

[0030] 1. Select 20 grass carp from the same source with similar age and size, body length 20-30cm, and carry out experiments on individuals and groups.

[0031] 2. Put the grass carp into the central cylinder 1, and after 7 days of adaptation, start to feed the same amount of the grass carp's favorite bait in containers of various shapes, which is convenient for long-term experimental observation.

[0032] 3. The distribution of grass carp during the day and night was continuously photographed and recorded with an infrared camera, and the continuous observation time was 10 days.

[0033] 4. Record the distribution of grass carp at 9:00, 12:00, and 20:00 every day, and the one with the highest distribution probability in a certain shape container indicates the preference for that shape.

example 3

[0034] Example 3. Spatial selection experiment of Chinese sturgeon

[0035] 1. Select 20 Chinese sturgeons from the same source and 5 months of age with similar specifications, body length 20-40cm, and conduct experiments on individuals and groups.

[0036] 2. Put the experimental fish into the central cylinder 1, and after 9 days of adaptation, start to feed the same amount of the Chinese sturgeon favorite bait in containers of various shapes, which is convenient for long-term experimental observation.

[0037] 3. The distribution of Chinese sturgeon during the day and night was continuously photographed and recorded with an infrared camera, and the continuous observation time was 10 days.

[0038] 4. Record the distribution of Chinese sturgeon at 9:00, 12:00, and 20:00 every day, and the one with the highest distribution probability in a certain shape container indicates the preference for that shape.

Abstract

The invention relates to a device and a method for selecting aquatic animal space shapes, and the device comprises a center cylinder and selecting containers, wherein six selecting containers which are evenly distributed are communicated with the center cylinder, each selecting container consists of three containers which are communicated with one another and are in different shapes, the selecting containers are communicated with the center cylinder through passages, the arrangement sequences of the three containers in each of the selecting containers are different, each container is rectangular, annular or round. The starting containers of every two selecting container in the same straight line are the same in the shape. The experimental fish are placed into the device and the probabilities that the experimental fish appear respectively in the three different-shaped containers are calculated, the higher probability that the experimental fish appear in the containers with a certain shape means that the experimental fish prefer to the containers with the shape. The device and the method can optimize an aquatic animal culturing system and establish space shapes loved by cultured aquatic animals. More considerable economic benefits are realized and technical support is provided for species protection at the same time.

Description

technical field [0001] The invention belongs to the field of environmental science, and in particular relates to a device and a method for selecting the spatial shape of aquatic animals. Background technique [0002] Under artificial breeding and ex situ protection, the breeding system of aquatic animals has circular, rectangular and circular shapes, but there is no relevant technical information about the environment that aquatic animals prefer. At the same time, aquatic animals exhibit different swimming behaviors in different spaces. For example, the Chinese sturgeon likes to swim around the circumference of a circular tank, and swims faster; swims along the long side of a rectangular pool, and swims faster. slow. Different aquatic animals may have different spatial shape preferences. [0003] In the construction of fishways, it is necessary to build a rest pool for fish to rest during their ascent. The shape of the rest pool may affect the use efficiency of the fishway...
