Controlled Ghost Fishing: Effects of Soaking Times and Mesh Sizes on Catchability in Trammel Net Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...

Phylogenetic distribution of regeneration and asexual reproduction in Annelida: regeneration is ancestral and fission evolves in regenerative clades

, 2016
Regeneration, the ability to replace lost body structures, and agametic asexual reproduction, such as fission and budding, are post-embryonic developmental capabilities widely distributed yet highly variable across animals. Regeneration capabilities vary

Molecular Investigation of the Diversity of Cirratulidae (Annelida) Doubles the Number of Known Species in European Waters

Zoologica Scripta, EarlyView.
ABSTRACT Cirratulidae is a group of common marine benthic annelids with about 397 nominal species described worldwide, 58 of which are reported in European waters. Due to the general morphological homogeneity among species from several genera, this group is considered difficult to identify to species level, has a complex taxonomical and nomenclatural ...

Light-Mediated Toxicity of Porphyrin-Like Pigments from a Marine Polychaeta

Marine Drugs, 2020
Porphyrins and derivatives form one of the most abundant classes of biochromes. They result from the breakdown of heme and have crucial physiological functions. Bilins are well-known representatives of this group that, besides significant antioxidant and

A new record of an interesting parasitic rotifer Balatro calvus Claparéde, 1867 in Hungary [PDF]

, 2006
Although widely distributed the parasitic rotifer Balatro calvus CLAPARÉDE, 1867 has only been sporadically observed. Here we document the presence of this species in enchytraeid (Annelida) specimens from different regions of ...

Influence of Chironomus riparius (Diptera, Chironomidae) and Tubifex tubifex (Annelida, Oligochaeta) on oxygen uptake by sediments. Consequences of uranium contamination [PDF]

, 2008
The diffusive oxygen uptake (DOU) of sediments inhabited by Chironomus riparius and Tubifex tubifex was investigated using a planar oxygen optode device, and complemented by measurements of bioturbation activity.

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 4, Page 198-213, June 2025.
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.
