Two bongo zooplankton samplers are described and the methods of construction given. Each sampler consists of a pair of nets mounted so that the mouth openings of the rigid body sections are on either side and in front of the towing wire. The results of tests comparing the bongo samplers with a 1-m ring net and the Gulf III encased sampler indicate that the bongo samplers give a more representative sample of the ichthyoplankton community than either of the other two types. The results of testing the bongo samplers for filtration efficiency and the effects of different mouth areas, towing distances and towing speeds show that none of these factors had a significant effect upon the catch per volume of water filtered.
