Preliminary results on the daily and seasonal rhythms of cuttlefish Sepia officinalis (Linnaeus, 1758) locomotor activity in captivity [PDF]

open access: yes, 2017
Cephalopods are considered as an alternate group for aquaculture species diversification [1,2], not only because they are a good food source (highly appreciated in some worldwide markets, e.g., Portugal, Spain, Italy and Asia) and have the potential to ...

Biosynthesis and Characterization of Melanin Extracted From Solanum tuberosum and Mucuna deeringiana

open access: yesJournal of Chemistry, Volume 2026, Issue 1, 2026.
A growing interest in finding accessible and low‐cost sources of melanin has emerged due to its wide range of applications. This work demonstrated the use of Mucuna deeringiana as a source of L‐DOPA, and Solanum tuberosum of tyrosinase in eumelanin biosynthesis.

European cephalopods distribution under climate-change scenarios

open access: yesScientific Reports, 2021
In a context of increasing anthropogenic pressure, projecting species potential distributional shifts is of major importance for the sustainable exploitation of marine species. Despite their major economical (i.e. important fisheries) and ecological (i.e.

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

open access: yesFisheries Management and Ecology, Volume 32, Issue 6, Page 405-417, December 2025.
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 ...

CHEMICAL BIO-COMPOUNDS AND FUNCTIONAL PROPERTIES OF RAW AND PROCESSED CUTTLEFISH, SEPIA OFFICINALIS (MOLLUSCA: CEPHALOPODA)

open access: yesFood and Environment Safety, 2018
Cuttlefish is one of the most economically important cephalopods with rich taste and few inedible parts. The study was aimed at evaluating the nutrient, non-nutrients, free fatty acid and cholesterol compositions and functional properties of raw and ...

A hedgehog-like signal is involved in slow muscle differentation in Sepia officinalis [PDF]

open access: yesInvertebrate Survival Journal, 2007
In the tentacle of Sepia officinalis, smooth-like, helical and cross-striated fibres deriving from different populations of myoblasts are present. Myoblasts appear at different times during the development and express two muscle-specific transcription ...

No Sex‐Differences in Learning Trap‐Gap Problems in Zebra Finches

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
This study examined whether male zebra finches, which play a larger role in nest building, show superior physical cognition compared to females using trap‐gap tasks. Contrary to expectations, no sex differences were found in learning or task transfer performance, and most birds relied on simple cue‐based strategies rather than object–gap relationships.
