However, the use of live bait did not significantly affect bluefin CPUE but significantly increased yellowfin CPUE.
Sea turtle CPUE was significantly higher in control nets (mean CPUE = 26.7 ± 3.3 s.e).e
The most recent study during the 1996 1997 season found that the highest number of lobsters per trap occurred between depths of 112 to 165 m at Islas Robinson Crusoe and Santa Clara with a CPUE of 10 lobsters per trip compared to 32 per trip at Isla Alexander Selkirk, and 174 per trip at Islas Desventuradas [49].
Pk can be estimated by the ratio between total fishing trips per ground and the number of trips where the target species was found at profitable levels, i.e., for those CPUE that generated net revenues greater than or equal to variable costs of fishing effort.
Early tagging cruises had relatively low bluefin CPUE but after we understood the preferred ocean conditions for bluefin tuna, our bluefin CPUE increased considerably[8].
However, recent stock assessments suggest that the spawning stock biomass have remained at approximately similar levels during this period of high CPUE [16].
Predicted and actual CPUE data are from the high catch area of the NCDMF gillnet survey, and Loess lines represent smoothed CPUE trends.
However, by utilizing the parameters which describe the diel variation transition estimated from the commercial CPUE data and compensating for the survey design effect, the survey hake catch rates at noon were estimated to be 27% and 86% higher than at night for M. capensis and M. paradoxus, respectively.
Further, I integrated observations of Humboldt squid on each ROV dive with information on time-at-depth of the ROV, creating an "encounter rate" metric that can be used in ecosystem and fisheries models, similar to catch per unit effort (CPUE).
Initially, the economic cost to the fishing industry was relatively high with fishermen experiencing lower catch values and lower CPUE [catch per unit effort].
