[0002] At present, the existing filters only have the function of filtration, but do not have the function of selective filtration, and there is no selective filter for shellfish larvae. The common current method for the selection and filtration of shellfish larvae is to tie sieve silk bags of different specifications to the water pipe outlet or hold them by hand at the water pipe outlet. After filtering the larvae of one specification, the larvae are put back into the water, and then another sieve silk bag of a different specification is replaced for another filtration. Such operation is inconvenient, cannot separate two different specifications of larvae at the same time, and is cumbersome, causing greater damage to the larvae. Moreover, the larvae will accumulate during the screening process, affecting the quality and efficiency of the selection and filtration. Content of the Utility Model

[0023] The first selection filter 6 includes a first support 601, a first filter bag 602 is disposed around the outside of the first support 601, two first clamping blocks 603 are symmetrically and fixedly connected to both ends of the upper surface of the first support 601, and the inner walls of the first clamping blocks 603 are respectively clamped and connected to the outer walls of the second mounting ring 5;

[0024] The second selector filter 7 includes a second bracket 701. The outer side of the second bracket 701 is surrounded by a second filter bag 702. The mesh size of the first filter bag 602 is larger than that of the second filter bag 702. At both ends of the upper surface of the second bracket 701, two second clamping blocks 703 are symmetrically and fixedly connected. The inner walls of the second clamping blocks 703 are both engaged with the outer wall of the first mounting ring 4. By setting the first mounting ring 4, the second mounting ring 5, the first selector filter 6, and the second selector filter 7, when screening the larvae, first pour the larvae into the first selector filter 6.
