Summary: The accuracy of fish growth estimates depends on how samples are collected. Random sampling is inefficient and rarely random, while proportional otolith sampling (POS) has been shown to produce more accurate estimates compared to fixed otolith sampling (FOS) under ideal conditions. However, the influence of variables such as sample size, fishery selectivity, and fishing mortality on sampling bias is unclear.

Summary: Atlantic tarpon (Megalops atlanticus) supports an economically important fishery, but there is limited information on their fishery and population. A survey of anglers and fishing guides was conducted to address data deficiencies and understand the status and threats to Atlantic tarpon. The survey revealed a decline in fishing quality since the 1970s, with water and habitat quality as major threats. These findings highlight the importance of ecological knowledge from recreational anglers and fishing guides for the conservation of Atlantic tarpon populations.

Summary: The ecological and social dimensions of fisheries are being impacted by climate change. This study aims to identify key attributes of resilience in fisheries and connect them to social-ecological outcomes. By assessing 18 case studies, the researchers found that attributes such as population abundance, learning capacity, and responsive governance were the most important for building resilience. They also developed a typology and identified five fishery archetypes to guide stakeholders in improving resilience. Two pathways to resilience were observed: building ecological assets and strengthening communities, or building economic assets and improving governance.

Summary: Proteomics is a powerful technique to study how organisms respond to biological perturbations, but its use in ecological studies has been limited due to inadequate protocols for sampling and preserving animal tissues from the field. We optimized a workflow and showed that sampling non-model organisms from remote field sites is achievable and can provide extensive proteomic coverage without compromising protein integrity.
