Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aquaculture, more particularly to a bottom suction and sub-pool system for aquaculture. BACKGROUND

[0002] Bottom suction and sub-pool are routine operations in aquaculture. The feces, leftover feed and dead fry produced by the seedlings during the cultivation process will be deposited at the bottom of the pool. Over time, it will deteriorate, breed harmful bacteria and produce a large amount of ammonia nitrogen and nitrite, leading to water quality deterioration. Therefore, the bottom of the pool needs to be cleaned before the water quality deteriorates to avoid excessive accumulation of garbage at the bottom of the pool, which will affect the growth of seedlings. In addition, as the seedlings grow, the space in the original fry pool will become increasingly cramped. The competition between seedlings will also intensify, and the accumulation of garbage at the bottom of the pool will further affect the cultivation of seedlings. At this time, the fry pool needs to be sub-pooled. The main sub-pool methods today are net capture, siphon, light induction or food induction.

[0003] However, due to the need for additional arrangement of a suction pipe in the prior art for bottom suction, the sub-pool methods of net capture, siphon and light induction stimulate the seedlings too much, which can easily cause mechanical damage to the seedlings and are complicated to operate. In addition, the use of food induction for sub-pooling will further increase the accumulation of garbage at the bottom of the fry pool, requiring an additional bottom suction operation and increasing the workload.
