Cal Poly University researchers conducted two separate tag and recapture studies of nearshore fish populations along California's central coast. Three locations were sampled that have experienced different degrees of fishing pressure. Big Creek MPA has been closed to all fishing from 1993 onwards and is the farthest from port of all locations. Cambria lies closest to port of the three locations...

A number of methods for estimating trends in relative abundance based on standardized catch-per-unit-effort (CPUE) are discussed, including general linear and additive models, habitat-based standardization, neural networks, and regression trees. Methods and criteria for testing among various standardization techniques are presented and recommendations for future research are presented. Authors’

This study used catch/effort (CPUE) and length-frequency (L/F) data to evaluate the status of 26 fish species in mangroves Dongzhaigang National Reserve, Hainan Province, China, sampled 2009 (16 species), 2014 (18 species) 2020 (15 using CPUE length-based Bayesian biomass (LBB) method. The CPUE, both number weight, was lower than again 2020, with low attributed pollution due shrimp, pig duck fa...

Penaeid shrimp is a major resource in India contributing about 7.4% of the total marine fish landings. They are mostly landed by small mechanized trawlers. Shrimp trawling generates large quantities of bycatch mostly consisting of juvenile fishes, due to use of small mesh size in codends of trawl nets. Juvenile Fish Excluder cum Shrimp Sorting Device (JFE-SSD) is a bycatch reduction device with...

This study aimed to determine the impact of hook and bait type on catch composition per unit effort. Effects types composition, effort (CPUE), length weight distributions in demersal longline fishery were determined by experimental surveys sets Aegean Sea. A total 12 samplings corresponding 4800 fishing performed between April 2014 September 2014. Two types; sardine (Sardina pilchardus) grooved...

The catch per unit effort (CPUE), population structure, sex ratio, and reproductive aspects of the invasive blue crab Callinectes sapidus Rathbun were studied in Monolimni Lagoon adjacent coastal waters estuarine area Evros River (Northeast Aegean Sea, Eastern Mediterranean). CPUE varied both seasonally spatially; higher values recorded summer fall lagoonal stations characterized by shallow dep...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...
