Intercalibration of MOCNESS and Bongo nets: Assessing relative efficiency for ichthyoplankton
The evaluation in catchability of egg and larval fish with the 0.61-m Bongo and the 1-m2 Multiple Opening and Closing Net Environmental Sensing System (MOCNESS) was conducted as part of a paired station analysis. The two samplers were deployed on 331 stations on Georges Bank during the US GLOBEC program from January through June for years 1996 and 1997. Significant differences were found when combined catches of all eggs and all larvae for each sampler were compared. Overall catches of larvae from the MOCNESS were 3 to 5 times greater than those from the Bongo. Gear effects were modeled and revealed that the catches in 14 of the 22 dominant taxa were significantly different between sampling gear. The differences between samplers during diel intervals for the taxa proved not to be significantly different.
