Towards Implementing Multispecies Harvest Strategies That Are Robust to Interacting Populations

Fish and Fisheries, Volume 26, Issue 5, Page 923-941, September 2025.
To advance the implementation of fisheries management that is robust to interacting populations (RIP), ecosystem management approaches can be structured using four main categories: (A) whole‐of‐ecosystem; (B) focus or key species; (C) species of conservation concern; and (D) pest or climate‐immigrant species.

Serial spawning and batch fecundity of merluccius capensis and m. Paradoxus [PDF]

, 2011
Histological analysis of the ovaries and the presence of multiple modes in oocyte size frequency distribution of Cape hake Merluccius capensis and M. paradoxus indicates that they are serial spawners.

Perceptions of Key Stakeholders on Current Methods and Technologies Used in Monitoring and Control of Fisheries Activities in Namibia's Exclusive Economic Zone (EEZ)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 3, March 2025.
ABSTRACT This study assessed stakeholders' perceptions of current methods and technologies for monitoring and controlling fisheries activities in Namibia's Exclusive Economic Zone (EEZ). The research was prompted by reports of illegal fishing and inadequate resources for effective oversight. Understanding stakeholders' views is crucial for policymakers

Potential Spatial Mismatches Between Marine Predators and Their Prey in the Southern Hemisphere in Response to Climate Change

Global Change Biology, Volume 31, Issue 2, February 2025.
Global change is reshaping marine habitats, altering predator–prey interactions and food web dynamics. Using Boosted Regression Trees, we assess habitat suitability shifts for crustaceans, fish, penguins, and pinnipeds across three Southern Hemisphere regions from 1850 to 2100 under two climate scenarios.

Life‐history parameters of adult females of Merluccius capensis (Gadidae) off the south coast of South Africa

Journal of Fish Biology, Volume 105, Issue 3, Page 626-639, September 2024.
Abstract This study explores the life‐history parameters of female Merluccius capensis off South Africa (N = 1819) during 2014–2016, including gonadosomatic index (GSI), length‐at‐maturity, length–weight relationships, and condition indices (relative condition [k] and Fulton's condition factor [K]). We detected weak indications of two peaks of spawning

Effects of environmental variables on survey catch rates and distribution by size of shallow- and deep-water Cape hakes, Merluccius capensis and Merluccius paradoxus off Namibia [PDF]

, 2017
In order to study the effects of temperature, oxygen, salinity and time of day onsurvey trawl catches, we modeled observed catches of juvenile, small, medium and large hakes per station as functions of zenith angle of the sun, geographical position, year,

Spawning patterns of shallow-water hake (Merluccius capensis) and deep-water hake (M. paradoxus) in the Benguela Current Large Marine Ecosystem inferred from gonadosomatic indices [PDF]

, 2015
We use gonad- and body-weight data from 54,000 samples of Merluccius capensis and Merluccius paradoxus collected in all months of the years between 1991 and 2013 to infer peak spawning periods and areas in the Benguela Current Large Marine Ecosystem.
