Bionic roe releaser

The utility model relates to a bionic roe releaser which comprises a roe storage bin, a roe releasing bin, a winch and a control switch. A roe releasing gate is arranged at the lower end of the side wall of the roe releasing bin, and a bottom support is arranged on the bottom of the roe releasing bin. The winch is used for controlling opening or closing of the roe releasing gate. The bottom support is used for supporting roe particles in the roe releasing bin upwards when roe is released, so that the roe is made to be released out from the opened roe releasing gate at the lower end of the side wall of the roe releasing bin rather than be released from the bottom end of the roe releasing bin, so that the situation that the roe generates downward acceleration at the initial moment of roe releasing is avoided. The bionic roe releaser is simple in structure, convenient and fast to operate, high in automation degree and capable of simulating natural spawning and roe particle releasing processes of different fishes, namely the fishes laying drifting type roe and the fishes laying demersal roe, the roe releasing speed and the sustained releasing time can be controlled, and quantitative tests of roe movement are facilitated.
