Distribution of calanoid copepods in the Arabian Sea and Bay of Bengal

摘要: The distribution of calanoid copepods from the northern Arabian Sea and Bay Bengal is discussed in relation to thermocline. inshore offshore zonation a neritic, shelf an oceanic communities was traced based on species composition. Numerical abundance high stations. Secondary production considered terms copepod density showed ratio 2:1 between Bengal. water column top layer thermocline surface dominated by Acrocalanus spp. Paracalanus spp., Eucalanus Undinula vulgaris Euchaeta In discontinuity attenuatus, Scolecithricella ctenopus, Haloptilus longicornis Lucicutio flavicornis were encountered. deeper collections bathypelagic viz. Heterostylitis longicornis, L. clausi, Amallothrix indica Euaugaptilus nudus have been recorded here for first time
