Evaluation of Catch Performance and Environmental Impact of Technical Gear Modifications for a More Sustainable Scallop Dredging Fishery

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions

Rocking together: a report on a biological interaction between a non-native sea anemone and a sea squirt in southeastern Brazil

Ocean and Coastal Research
This study provides an in-depth examination of the ecological interaction between the non-native Diadumene lineata (Verrill, 1869) sea anemone, and the Polysyncraton amethysteum Van Name, 1902 colonial ascidian.

Role of hemocytes in invertebrate adult neurogenesis and brain repair [PDF]

Invertebrate Survival Journal, 2015
The repair of lesions of the central nervous system (CNS) varies widely throughout the animal kingdom. At the level of neuronal replacement lie the major differences in CNS regeneration.

Salinity-mediated limitation of asexual reproduction in the colonial ascidian Polyandrocarpa zorritensis

Frontiers in Ecology and Evolution
Ascidians are among the most common invasive marine invertebrates worldwide. Many species of non-indigenous ascidians (NIAs) have successfully colonized the Mediterranean Sea, notably within anthropized coastal lagoons and harbors.

Distribution and invasiveness of a colonial ascidian, Didemnum psammathodes, along the southern Indian coastal water

Oceanologia, 2016
Ascidians are well known worldwide for their rapid invasions and also for the presence of potential biomedical molecules. Members of the family Didemnidae are widely distributed in tropical waters and they are reported to be among the families possessing

Establishing genetically controlled, closed colonies of an ascidian

Development
Abstract Recent technological advances have made many “non-model” organisms accessible for experimental studies. However, reference inbred strains were not necessarily available, especially in marine invertebrates, and genetic background of organisms used for experiments are often non-uniform.

Integrative evidence for the first record of Clavelina oblonga (Ascidiacea: Clavelinidae) in a highly turbid Caribbean habitat

Ciencias Marinas
Ascidians are key components of benthic marine communities worldwide. They contribute to biofouling and increase the structural complexity of benthic habitats by providing substrate for other organisms.

Looking for putative phenoloxidases of compound ascidians: haemocyanin-like proteins in Polyandrocarpa misakiensis and Botryllus schlosseri

, 2012
Phenoloxidases (POs) constitute a family of copper-containing enzymes widely distributed among invertebrates. They exert a pivotal role in immune defences as they induce cytotoxicity through the conversion of phenols to quinones and the production of ...

Settlement Patterns of Corals and other Benthos on Reefs with Divergent Environments and Disturbances Histories around the Northeastern Arabian Peninsula

Frontiers in Marine Science, 2017
Larval supply is a principal factor determining the establishment, structure, and diversity of sessile benthic assemblages on coral reefs. Benthic reef communities in north-eastern Arabia have been subject to recurrent disturbances in recent years, and ...

Tunicate-associated bacteria show a great potential for the discovery of antimicrobial compounds.

PLoS ONE, 2019
Tunicates (Ascidians, sea squirts) are marine protochordates, which live sedentary or sessile in colonial or solitary forms. These invertebrates have to protect themselves against predators and invaders.
