Abstract Objective We sought to (1) assess the validity of a catch orientation measure for mountain trout angling in North Carolina, (2) segment Carolina anglers based on orientation, (3) explore associations between classified clusters and other angler non‐catch‐specific characteristics, (4) classification preferences clusters. Methods were focus our investigation surveyed with an online questionnaire. validated four‐dimensional latent structure measures clustered attitudes. ran multiple cluster comparative tests unique characteristics each cluster. Result identified three clusters: non‐catch‐oriented anglers, trophy consumptive anglers. Consumptive their positive attitudes towards catching many fish keeping fish, using natural bait artificial lures, streams least restrictive rules, being motivated by social activity‐general factors. Trophy (large) activity‐specific motive fishing sport. Also, they prefer that are stocked have catch‐and‐release regulations half year. Non‐catch‐oriented scored lowest most metrics, motives “nature,” preferred abundant dispersed network streams. Conclusion Our study divergence orientations directed at particular sport family, implications future applications recreation specialization, potential improvements measures. These profiles also provide managers information assist meeting management plan goals, examining access issues, engaging public. highlight importance pragmatic sport‐fish‐family‐specific inquiries into diversity discuss applied these results.

Abstract Objective We evaluated the effect of a 381‐mm minimum length limit (MLL) on saugeye (female Walleye Sander vitreus × male Sauger S. canadensis ) population and fishery characteristics implemented in Ohio reservoirs 2011. Methods Using before‐after–control‐impact study design ( n = 6 control populations 11 impact that received MLL), we compared total CPUE, age‐2+ proportional stock density‐harvestable (381‐mm), at age 2 (to index growth) determined from standardized gill‐net surveys angler effort, catch rate, harvest harvest, yield, satisfaction obtained creel surveys. Result found evidence MLL led to an increase CPUE but had no other metrics. In regulation reservoirs, rates declined following implementation. Total harvested did not significantly response MLL, combined with decreased rates, yield was suppressed relative reservoirs. However, over 90% anglers reported they were satisfied during Conclusion Despite marginal influence failure supported MLL. Our results suggest effects regulations may be marginal, managers should consider nuances decisions.

The increasing global demand for aquatic products and decline in wild fisheries pose a challenge achieving the United Nations’ Sustainable Development Goal 14, which is to conserve sustainably use marine resources. depletion of fish populations due overfishing, destruction habitats as well climate change has adversely affected ecosystems, leads further pressure establishing food security. To meet rising products, countries have turned aquaculture, but industry itself faces many environmental challenges, particularly wastewater management. This review explores potential using biofloc technology (BFT) treat wastewater. BFT utilises microbial ecosystem processes remove excess nutrients acts natural “cleaning” mechanism. It transforms organic waste into valuable biomass, enhances water quality minimises ecological footprint aquaculture. In this way, reduces amount solid generated, increases level dissolved oxygen creates an environment that less conducive growth harmful bacteria, thus reducing need chemical treatments. paper also discusses role toxic remediation by analysing nature composition aquaculture study provides comprehensive overview mean values various parameters water, compares them with standards.
