SlotLim: Catch advice for data‐limited vertebrate and invertebrate fisheries managed by harvest slot limits

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
SlotLim is a new harvest control rule that produces catch advice for vertebrate and invertebrate fisheries managed by harvest slot limits. The methodology is data‐limited, requiring a few years of fishery‐dependent data and life‐history information. The ‘SlotLim’ R package is available via CRAN. Abstract Minimum landing sizes are a fisheries management

Synergistic Effect of Salinity and 17β‐Estradiol on the Induced Feminization of Centropomus undecimalis: Histological, Hormonal, and Molecular Evaluation

Aquaculture Research, Volume 2026, Issue 1, 2026.
The scarcity of functional females in wild Centropomus undecimalis populations limits broodstock development for aquaculture. This study evaluated feminization of this protandrous hermaphroditic teleost under different salinity conditions using 17β‐estradiol (E2), administered orally to juveniles and via intramuscular implants to adults.

Measuring juvenile habitat quality for fishes and invertebrates

Biological Reviews, Volume 100, Issue 6, Page 2346-2395, December 2025.
ABSTRACT Identifying the role of marine and estuarine habitats in supporting fish and invertebrate populations during vulnerable juvenile life stages is essential to achieve effective conservation and fisheries management. There remains general agreement that: (i) the quality of juvenile habitat is best measured as the contribution of juveniles to ...

Beyond the Binary: Controlling Natural Sex‐Change in Hermaphroditic Fishes

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate ...

What acoustic telemetry can and cannot tell us about fish biology

Journal of Fish Biology, Volume 106, Issue 5, Page 1260-1284, May 2025.
Abstract Acoustic telemetry (AT) has become ubiquitous in aquatic monitoring and fish biology, conservation, and management. Since the early use of active ultrasonic tracking that required researchers to follow at a distance their species of interest, the field has diversified considerably, with exciting advances in both hydrophone and transmitter ...

Use of hatchery‐raised fish in validation of daily age estimates for juvenile Common Snook

Marine and Coastal Fisheries, Volume 16, Issue 6, December 2024.
Abstract Objective We investigated the validity of daily age estimates for juvenile Common Snook Centropomus undecimalis by using sectioned and sanded sagittal otoliths. Methods Common Snook have a protracted spawning season, which is problematic for validation of daily ages because a hatch date—needed to calculate age—cannot be reasonably assigned ...
