Problems solved by technology
However, in the process of breeding and domestication, chilled fish are usually used as bait and directly put into the water for feeding. The feeding time is long, the residual bait is large, and the water quality deteriorates rapidly. In practice, the effect is very poor.

Embodiment
[0012] Example: refer to Figure 1 to Figure 2 , a rope-clamp type squid breeding and feeding device, including a hemp rope body 1, wherein: the hemp rope body 1 has two strands 11 that can be untwisted and form an untwisting ring 12 of 1 to 10 cm; the hemp rope body 1 Fixers 2 are provided at both ends; a weight 3 is connected to the end of the hemp rope body 1 . The hemp rope body 1 is formed by twisting two rope strands 11, and the two rope strands 11 have the same direction of rotation as the hemp rope body 1, so that the untwisting ring 12 can be rotated slightly when the untwisting ring 12 is formed. 12 has the active force of gathering and returning. Combined with the pulling of the weight 3's own gravity, the untwisting ring 12 can still have a strong clamping recovery force when the number of untwisting rings 12 is small. The fixer 2 is fixed on the two ends of the hemp rope body 1, which can prevent the rope strands 11 and the hemp rope body 1 from untwisting.

The invention discloses a clamping rope type cuttlefish breeding and feeding device which comprises a hemp rope body. The hemp rope body comprises two rope strands capable of being unwound and forming unwinding rings of 1-10cm. Fixers are arranged at two ends of the hemp rope body, and a mass block is connected with the tail end of the hemp rope body. The hemp rope body is formed by twisting the two rope strands, each rope strand is self wound in the direction identical with that of the hemp rope body, and the two rope strands have folding and recovering action force on the unwinding rings the moment the unwinding rings are formed. By means of the combination of the folding and recovering action force and the self gravity of the mass block, the unwinding rings still have strong clamping recovering force when the unwinding rings are few in number. The fixers are fixed at two ends of the hemp rope body and can prevent the rope strands and the hemp rope body from being unwound. The device has the advantages of being novel in structure, high in bait utilization rate, good in food calling effect, not prone to corrupt water quality and low in cost.
Description
technical field [0001] The invention relates to a breeding and acclimation bait feeding device, in particular to a rope-clamp type squid breeding and feeding device. Background technique [0002] Sepia cephalopods ( Cephalopoda ), Sepia ( Sepioidea ), Squid ( Sepiidae ), Sepia ( Sepia ), is a benthic species with strong warm water in shallow seas, inhabits offshore waters with a water depth of 15-100m in the continental shelf area, and is distributed in the Indian Ocean-West Pacific Ocean. In the South China Sea, the spawning season is from October to February of the following year. During this period, resources are abundant at water depths of 60-100m; from March to May, cave tours are carried out at depths of 15-30m near the shore. The eggs are mostly attached to substances such as gorgonians, sargassum, bamboo branches or strings. The squid is relatively large in size (maximum carmine length 40cm, weight skg), short breeding cycle, rapid growth, delicious meat, hig...
