Towards more selective Mediterranean trawl fisheries: are juveniles and trash excluder devices effective tools for reducing undersized catches?

Scientia Marina, 2018
Mediterranean trawl fisheries are characterized by a critical combination of high fishing effort and low size at first capture for most commercial species.

Valorization of Seafood Processing Discards: Bioconversion and Bio-Refinery Approaches

Frontiers in Sustainable Food Systems, 2021
The seafood industry generates large volumes of waste. These include processing discards consisting of shell, head, bones intestine, fin, skin, voluminous amounts of wastewater discharged as effluents, and low-value under-utilized fish, which are caught ...

Body Length, Tow Conditions, and Guide-Net Angle as Joint Predictive Contributors to Catch Loss in a Marine Mammal Bycatch Reduction Device: An Interpretable Machine Learning Analysis

Fishes
Guide-net marine mammal bycatch reduction devices (BRDs) are intended to reduce protected species interactions in trawl fisheries, but their use may also cause catch loss of commercial fish and cephalopods.

Exploring the Fishing by Stake-nets inside the Qeshm Island\'s Marine Protected Area [PDF]

بوم‌شناسی آبزیان, 2018
High population pressure in coastal areas has led to loss in many mangrove areas. Although these areas are fish nursery grounds, but there are no accurate and up-to-date data available.

Harvest of Southern Highbush Blueberry with a Modified, Over-the-Row Mechanical Harvester: Use of Soft-Catch Surfaces to Minimize Impact Bruising

Agronomy, 2021
Harvest of fresh market, southern highbush blueberries (SHB) is labor intensive and costly, leading to a demand for alternative harvest methods. Recent research has shown potential for mechanically harvesting blueberries with minimal bruising by using a ...

Modulation of habitat-based conservation plans by fishery opportunity costs: a New Caledonia case study using fine-scale catch data. [PDF]

PLoS ONE, 2014
Numerous threats impact coral reefs and conservation actions are urgently needed. Fast production of marine habitat maps promotes the use of habitat-only conservation plans, where a given percentage of the area of each habitat is set as conservation ...

Two intense decades of 19th century whaling precipitated rapid decline of right whales around New Zealand and East Australia.

PLoS ONE, 2014
Right whales (Eubalaena spp.) were the focus of worldwide whaling activities from the 16th to the 20th century. During the first part of the 19th century, the southern right whale (E. australis) was heavily exploited on whaling grounds around New Zealand

Impact of water development on river flows and the catch of a commercial marine fishery

Ecosphere, 2020
The growing demand for freshwater resources has led to dam construction and water diversions in a majority of the world's large rivers. With an increasing demand for freshwater, trade‐offs between water allocations and the preservation of ecological ...

Catching the wisps: Stellar mass-loss limits from low-frequency radio observations

Astronomy & Astrophysics
The winds of low-mass stars carry away angular momentum and impact the atmospheres of surrounding planets. Determining the properties of these winds is necessary to understand the mass-loss history of the star and the evolution of exoplanetary atmospheres.

Grey seal induced catch losses in the herring gillnet fisheries in the northern Baltic

NAMMCO Scientific Publications, 2007
The interaction between grey seals (Halichoerus grypus) and the Baltic gillnet fishery for herring (Clupea harengus) during the period 2000-2005 was investigated, by comparing and contrasting 3 sources of information: data from the European Union (EU) official logbook system, data from a voluntary logbook system and data from field studies.
