| Abstract: | Monitoring results in the Lancelet Protected Area in Huangcuo,Xiamen from July 1994 to July, 1995 indicate that the area houses a comparatively large amount of lancelet(average inhabiting density is 142 ind/m2 and average biomass 8. 10g/m2 ), without much difference with the results obtained in the two surveys in 1990. Most of'the lancelet are 11 to 40 mm in body length. They mature sexually mostly in the first twenty days of April and reproduce thereafter to the first ten days of May. The animal inhabit mostly in the coarse medium sandy area where the organic content is low, averagely 0. 14 (m/m). In the Protected Area there live 58 species of benthos, majorly polychaeta, mullusca and crustacea in terms of species composition and echinoderm in terms of quantity. The species composition discreases from south to north. Lancelet in the Protected Area feeds on 81 species of diatoms, mainlyCoscinodtiscus, Na vicula a nd Nitzschia. This paper has proposed some recommendation s for the conservation of lancelet. |
