Equilibria and Isosteric Heat of Adsorption of Methane on Activated Carbons Derived from South African Coal Discards

open access: yesACS Omega, 2020
Isosteric heat of adsorption (Hst) is critical for evaluating the thermal effects of adsorption-based storage systems. Poor management of the thermal effects of an adsorptive storage system often alters the overall performance of the storage system.

Valorisation of fish discards assisted by enzymatic hydrolysis and microbial bioconversion: Lab and pilot plant studies and preliminary sustainability evaluation

open access: yes, 2020
The new EU fishing policies (Landing Obligation) are aimed at preventing the elimination of fishing discards overboard. These new biomasses that have to be landed from 2019 force to stablish valorisation protocols since, in most cases, they cannot be ...

Stock assessment of sardine (Sardina pilchardus, Walb.) in the Adriatic Sea with an estimate of discards

open access: yesScientia Marina, 2005
Analytical stock assessment of sardine (Sardina pilchardus, Walb.) in the Adriatic Sea from 1975 to 1999 was performed taking into account the occurrence of discarding at sea of sardine caught by the Italian fleet.

On the economic nature of consumers’ willingness to pay for a selective and sustainable fishery: A comparative empirical study

open access: yesScientia Marina, 2018
The EU Landing Obligation (LO) bans discards to incentivize a more selective and sustainable fishery. This regulation may induce a cost to the fishing industry that could be transferred to final fish consumers. We aim to assess the consumers’ reservation

Global marine fisheries discards: A synthesis of reconstructed data

open access: yes, 2018
As part of the global marine fisheries catch reconstruction project conducted by the Sea Around Us over the last decade, estimates were derived for discards in all major fisheries in the world. The reconstruction process derives conservative but non-zero

Attendance of scavenging seabirds at trawler discards off Galicia, Spain

open access: yesScientia Marina, 2003
The occurrence of scavenger seabirds at fishing trawlers was studied off Galicia, Spain. A total of 9,368 seabirds of 23 species were recorded during 92 fishing operations in 1998 and 1999.

Fish distributions reveal discrepancies between zonal attachment and quota allocations

open access: yesConservation Letters, 2020
The oceans’ fisheries contribute to human wellbeing by providing essential nutrients, employment, and income. Changes in fish distribution, due to climate change or stock expansion, jeopardize conservation objectives because fishers catch more than is ...

The effects of two different net modifications on reducing discards in the trammel net fishery for prawn in Mersin Bay

open access: yesOceanological and Hydrobiological Studies, 2023
The discarded species caught in prawn trammel nets damage the nets and cause a serious labor loss problem for fishers. In the present study, a 15 cm high greenhouse plastic film and a greenhouse shade cloth net were fitted between the lower parts of the ...

Impacts of fisheries on seabird communities

open access: yesScientia Marina, 2003
Long-line by-catch of albatrosses and petrels may soon lead to species extinctions. Set-net bycatch has caused major reductions in certain seabird populations. Some fisheries may decrease numbers of seabirds by reducing abundance of prey-fish.
