Last, we used an area-weighed recursive algorithm that considered spatial autocorrelation for each year within the analysis period. Commercial South Atlantic swordfish catch data from the Brazilian pelagic longline fleet were analyzed. Swordfish accounted for the highest spatial dependence in distance in 2005 (456 km), 2008 (111 km), 2012 (80 km), and 2014 (443 km), as well as for the lowest in 2011 and 2013 (average = 15.45 km).

A sensitivity analysis was thus applied to the German Eel Model for the River Weser to evaluate how uncertainties in ten key input variables affected predicted eel escapement biomass. Uncertainty in the proportion of female eels and their age-specific natural mortality, hydropower-related mortality, and restocking had the largest influence on overall uncertainty. Conversely, uncertainty in eel predation by cormorants and age composition of immigrating male eels had small effects on outcome uncertainty.

This study reports scientific evidence of natural reproduction of North American rainbow trout (<i>Oncorhynchus mykiss</i>) in three alpine rivers in Bavaria, Germany. Eggs collected from spawning redds were determined to be rainbow trout in all study rivers. In the river Leitzach, where spawning was exclusively observed in spring, electrofishing revealed a balanced length-frequency distribution with a high abundance of rainbow trout and a high proportion of individuals < 10 cm. In the rivers Isar and Traun, spawning was observed in winter and supposedly also in spring, according to local reports. Rainbow trout < 10 cm were also observed in these two rivers during electrofishing surveys but were less abundant than in the river Leitzach. Genetic factors and river-specific environmental and climatic conditions may have contributed to the success or failure of rainbow trout reproduction.

We evaluated effects of stocking on cobia size composition in this data-limited fishery to understand stocking limitations and explore possibilities for future projects. Total length of cobia was significantly shorter after stocking than before stocking, with mostly small fish caught mainly by nets, an unusual pattern for cobia. Total length also varied significantly among bottom types. Most of the cobia harvested were below the size at first maturity, which suggests that stocking increased the catch, but most fish harvested were immature, thereby potentially hindering stock recovery. For future projects, we recommend against the use of plastic tags for tagging hatchery cobia and propose releases that emulate natural spawning dynamics, alongside releasing fish at older ages.

To further understanding of drivers behind data contribution, we first assessed the willingness to share information, using response rates to optional questions asked during account registration, among three distinct groups of participants on an electronic citizen science platform for anglers: (i) registered and did not contribute data (registrants); (ii) registered and contributed data in a single year (contributors); and (iii) registered and contributed data in multiple years (sustained contributors). We next modeled demographic and fishery-specific questions to determine specific drivers of data contribution and sustained contribution. Willingness to share information upon registration was lowest among registrants, intermediate among contributors, and highest among sustained contributors. The answer to the question “How important is angling as a hobby for you?” was the main driver in moving from registrant to contributor and from contributor to sustained contributor (i.e., participants who considered angling a more important hobby were more likely to be contributors and sustained contributors). Additionally, the probability of being a contributor declined over time, and angler residence (postal codes) was a driver of sustained contribution.
