Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

A first record of the Smallfin Gulper Shark Centrophorus moluccensis Bleeker, 1860 (Chondrichthyes: Squaliformes: Centrophoridae) from the Andaman & Nicobar waters, Indian EEZ

Journal of Threatened Taxa, 2017
The Smallfin Gulper Shark Centrophorus moluccensis is reported for the first time from the Andaman & Nicobar waters of the Indian EEZ.  A male specimen of 785mm total length and weighing 2.34kg was landed by a motorized longliner at Burmanallah, South ...

DNA barcoding reveals the presence of Whitson's grenadier, Macrourus whitsoni, in sub‐Antarctic waters of South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni, in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South ...

Navigating morphometric minefields: Modelling heteroscedasticity in length‐conversion models

Journal of Fish Biology, EarlyView.
Abstract A common problem when combining data on species' traits from multiple sources is that researchers often measure the same trait in different ways. For example, the length of a shark can be measured in a straight‐line or over‐the‐body, and for lengths that include the tail (e.g., fork and total lengths), with the tail in ‘stretched’ or ‘natural’

ANALYZING TECHNICAL AND ECONOMIC INTERRELATIONSHIPS IN HAWAII'S LONGLINE FISHERY [PDF]

This paper provides an analysis of technical and economic interrelationships among species harvested in Hawaii's pelagic longline fishery. The results indicate that this multispecies fishery is characterized by a joint production process, meaning that ...

Species’ traits and exposure as a future lens for quantifying seabird bycatch vulnerability in global fisheries

Avian Conservation and Ecology, 2022
Fisheries bycatch, the incidental mortality of non-target species, is a global threat to seabirds and a major driver of their declines worldwide. Identifying the most vulnerable species is core to developing sustainable fisheries management strategies ...

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,

MODELING THE EFFECTS OF AREA CLOSURE AND TAX POLICIES: A SPATIAL-TEMPORAL MODEL OF THE HAWAII LONGLINE FISHERY [PDF]

We develop an economic model for a multi-species fishery that incorporates the spatial and temporal distribution of effort and fish stocks. Catchability coefficients and initial stocks are estimated from catch and effort data for each specific location ...

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

Meteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Using Natural Fibres and Indigenous Knowledge to Develop Alternatives to Plastic Ropes Used in Mussel Aquaculture

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
Aquaculture relies extensively on plastic materials, creating a need for lower‐plastic alternatives that retain the functional properties required for production. This study combined mātauranga Māori and science to identify natural plant fibres suitable for manufacturing mussel ropes and to evaluate their ability to catch and retain Greenshell mussel ...
