Abstract
An apparatus for collecting shellfish and the like comprises a first fence anchored in the ground to enclose a collection area, said fence comprising wall sections of a height to be scaled by shellfish, each of said wall sections having exposed on only the inner surface thereof a pair of vertically spaced conductors spaced less than the length of the shellfish and so as to be in the advancing path of the shellfish scaling the wall section from the inner side thereof. Means are provided for applying intermittent voltage pulses continuously to the conductors which pulses are spaced apart a time interval less than the time required for the shellfish to span the space therebetween.

An apparatus for collecting shellfish, comprising:
- a shellfish collection enclosure to enclose a collection area, said enclosure comprising insulating wall means of a height to be scaled by the shellfish, said wall means having exposed on only the inner surface thereof a pair of exposed vertically spaced conductors spaced less than the length of the shellfish and horizontally extending over the length of the wall means so as to be in the advancing path of the shellfish scaling the wall means from inside the enclosure, and means for applying intermittent voltage pulses of a value which are not hazardous to humans continuously to said conductors which pulses are spaced apart a time interval less than the time required for the shellfish to traverse the space therebetween.
