Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to a loach sorting platform, and more particularly to a loach male-female sorting platform. Background Technology

[0002] Loach is an important aquaculture species with high economic value due to its high nutritional value and large market demand. Artificial breeding is a crucial link in the large-scale, intensive artificial propagation of loach. During the breeding season, it is necessary to distinguish and sort the male and female parent loaches (i.e., sexually mature breeding loaches). Only by grouping and pairing well-developed male and female loaches in a certain proportion can efficient fertilization be guaranteed, resulting in high-quality fertilized eggs and ensuring a high fry emergence rate and robustness. Currently, sexing mainly relies on artificial observation of secondary sexual characteristics, with the most crucial criterion being the pectoral fin morphology: male loaches have larger pectoral fins with pointed tips and bony plates at the base of the second fin rays; female loaches have shorter pectoral fins with rounded tips. In addition, the swollen, soft, and full abdomen of female loaches during the breeding season is also an important auxiliary distinguishing feature.

[0003] Currently, the vast majority of fish farms and hatcheries use purely manual sorting methods. Operators typically work directly on rearing basins, troughs, or ordinary tabletops, resulting in problems such as low sorting efficiency, low accuracy and instability, and the potential to cause severe stress and physical damage to loach broodstock, leading to decreased physical condition, increased susceptibility to diseases like saprolegniasis, impaired gonadal development, and even death, ultimately harming the health and quality of the breeding population. Furthermore, the work is extremely labor-intensive. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a loach sex separation platform. This platform is simple in structure, easy to use, and low in manufacturing cost, making it economical and practical. It boasts high sorting efficiency, high accuracy, strong stability, and excellent sorting results. While ensuring sorting accuracy, it significantly improves sorting efficiency, reduces labor intensity, and minimizes harm to valuable parent fish, thus meeting the growing demands of modern aquaculture for precision, large-scale operations, and animal welfare.

[0005] To solve the above-mentioned technical problems, this utility model provides a loach sex sorting platform, including a sorting platform with a rectangular shallow trough design. The sorting platform is placed on an inclined support. From top to bottom, the sorting platform is divided into a loach waiting area and a loach sorting area by a partition A located in the upper middle part. Loach diversion areas are respectively set on both outer sides of the loach sorting area. The loach sorting area and the loach diversion areas on both sides are separated by two partitions B, both of which are... The system is designed to be inclined outwards. Loach diversion ports A are located at the lower outer ends of the two loach diversion zones. Loach diversion port B is located on the outer wall of the bottom end of the loach sorting zone. Loach diversion port B is located at the middle of the bottom of partition A. Water outlets connected to the loach diversion zones are located on both sides of the bottom of partition A. A water spraying device is installed at the front end of the sorting platform. The outside of the water spraying device is connected to a water pipe, and several evenly distributed water mist nozzles are installed on the inside of the water spraying device.

[0006] As a further improvement of this utility model, in order to prevent loaches from being physically damaged when passing through the diversion port, protective edging is provided around the edges of both loach diversion port A and loach diversion port B.

[0007] As a further improvement of this utility model, in order to reduce the stress response of loaches when they flow out of the diversion port, a slow-descent plate is provided on the outside of both loach diversion port A and loach diversion port B.

[0008] As a further improvement of this utility model, in order to ensure that the loaches are evenly distributed on the sorting table and to ensure the accuracy of sorting, several buffer strips are evenly distributed on the bottom plate of the loach sorting area.

[0009] As a further improvement of this utility model, in order to ensure the accuracy of sorting male and female loaches, a male and female loach indicator is provided on the side wall of the two loach diversion area.

[0010] Compared with the prior art, the present invention has the following advantages: ①This sorting table has a simple structure, is easy to use, has low manufacturing cost, and is economical and practical; ② High sorting efficiency, high sorting accuracy and strong stability, and good sorting effect; ③ While ensuring sorting accuracy, it significantly improves efficiency, reduces labor intensity, and minimizes damage to precious parent plants.
