Sampling comments: "larvae were sampled once per month during May to September in 1997 and from April to September in 1998... Samples were obtained by one "Z-stroke" per section with a frame net. The frame net was submerged into the water and pulled 1.5 m lengthwise 2-3 em over the waterbed... The frame net had a 25 x 25 em frame with mesh-width 0.5 mm"
