Functional morphology of cephalopod gills [PDF]

, 1987
There is a wealth of literature dealing with fish gills (Review, see Hoar & Randall, 1984), yet hardly anything is known about the gills of cephalopods. This is rather surprising considering the commercial importance of the cephalopods.

ElevatedpCO2drives lower growth and yet increased calcification in the early life history of the cuttlefish Sepia officinalis (Mollusca: Cephalopoda) [PDF]

, 2015
Ocean acidification is an escalating environmental issue and associated changes in the ocean carbonate system have implications for many calcifying organisms.

Steroidogenesis in the brain of Sepia officinalis and Octopus vulgaris

Frontiers in Bioscience, 2010
The presence of vertebrate-like steroids, steroidogenic enzymes and steroid receptors has been reported exclusively in cephalopods gonads. The role played by these steroids has been also recently investigated. We here give evidence of steroidogenic activity in the brain of cephalopods. The activity of two key steroidogenic enzymes: 3beta-hydroxysteroid

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

Fisheries Management and Ecology, Volume 33, Issue 2, Page 181-200, April 2026.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

Assessing Cephalopods Fisheries in the Strait of Sicily by Using Poor Data Modeling

Frontiers in Marine Science, 2021
Cephalopods, including octopuses, squids, and cuttlefishes, are exploited by both bottom trawl and small-scale fisheries (SSF) in most of the Mediterranean areas.

Shoaling behaviour in the European cuttlefishSepia officinalis

Ethology, 2021
AbstractGroup living is a common behavioural feature in many different animal species. It offers a multitude of fitness benefits, such as increased opportunities to find resources, improved predator vigilance and potentially even social learning. In cephalopods, social grouping behaviour has mainly been reported for squid species, with up to several ...

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

Fisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Siphonal zone structure in the cuttlebone of Sepia officinalis

Swiss Journal of Palaeontology, 2015
The evolutionary process through which the siphonal zone of the cuttlebone of Sepia replaced the tubular siphuncle seen in other shelled cephalopods is poorly understood. Recently, porous connecting stripes, interpreted as homologous to connecting rings of tubular siphuncles, were revealed in Sepia (Acanthosepion) cf. savignyi (Geobios, 45:13–17, 2012).

Gummies as a Novel Approach to Valorize Rainbow Trout Wastes

Journal of Food Science, Volume 91, Issue 3, March 2026.
ABSTRACT In this study, a potential waste management strategy was developed for the evaluation of marine and freshwater fish waste, which is chemically very similar. To this end, an unmet need has been addressed by converting by‐products from rainbow trout, a cold‐water fish, into functional and nutritious ingredients.

Considérations sur la systématique des Sepiidae (Cephalopoda) [PDF]

, 1964
Au cours des deux derniers siècles, plusieurs tentatives ont été faites pour subdiviser le genre Sepia ou pour classer les différentes espèces dans des catégories super-spécifiques ou super-génériques. C.
