Variations in Weight and Proximate Composition of Newly Hatched Octopus vulgaris (Cuvier 1797) Paralarvae

open access: yes, 2013
Survival and growth of juvenile octopi vary considerably. The objective of this research was to determine variations in weight, total lipids (TL), and total protein (TP) of newly hatched Octopus vulgaris paralarvae (0 days old) over the course of the ...

Swimming ability of the Carybdea marsupialis (Cnidaria: Cubozoa: Carybdeidae): implications for its spatial distribution

open access: yesJournal of Zoology, Volume 324, Issue 1, Page 1-10, September 2024.
In this paper we analyzed the swimming speed, effective velocity, effective displacement index (EDI) and proficiency of juvenile to adult specimens (ranging from 1.1 to 36 mm of the diagonal bell width) of the box jellyfish Carybdea marsupialis. Abstract Although usually considered part of the plankton, cubozoans are strong swimmers.

Stock discrimination of two European squids (Illex coindetii, Loligo forbesii) by statolith shape analysis

open access: yesFisheries Management and Ecology, Volume 31, Issue 3, June 2024.
Abstract We evaluated the feasibility of classifying ommastrephid and loliginid squid species by statolith shape analysis into fisheries management units or stocks. Statoliths of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) were studied from multiple areas of the North East Atlantic and Northern Mediterranean Sea during 2021 ...

The role of DNA methylation on Octopus vulgaris development and their perspectives

open access: yesFrontiers in Physiology, 2014
DNA methylation is a common regulator of gene expression and development in mammalian and other vertebrate genomes. DNA methylation has been studied so far in a few bivalve mollusk species, finding a wide spectrum of levels.

The habitat preferences of Idiosepius pygmaeus and their use of conspecific cues

open access: yesMarine Ecology, Volume 45, Issue 3, June 2024.
Abstract The two‐toned pygmy squid (Idiosepius pygmaeus, Steenstrup, 1881) is a small, tropical cephalopod that inhabits seagrass meadows and is known to attach to blades of seagrass using a specialised adhesive organ. A global decline in seagrass habitat due to anthropogenic disturbances may threaten the species that rely on seagrass meadows for ...

Morphological and Molecular Characterization of Eggs and Paralarvae of Green Octopus, Octopus hubbsorum Berry 1953, from the Gulf of California

open access: yesDiversity
The green octopus, Octopus hubbsorum, is a merobenthic species that inhabits warm-temperate waters in the eastern Pacific. However, its similarity to some morphological characteristics of and its slight genetic divergence from Octopus mimus has led to ...

Fatty Acid Profile of Neutral and Polar Lipid Fraction of Wild Eggs and Hatchlings from Wild and Captive Reared Broodstock of Octopus vulgaris

open access: yesFrontiers in Physiology, 2017
The culture of Octopus vulgaris is constrained by unsolved problems in paralarvae rearing, mainly associated to the unknown nutritional requirements of this species in early stages.

A new way to understand migration routes of oceanic squid (Ommastrephidae) from satellite data

open access: yesRemote Sensing in Ecology and Conservation, Volume 10, Issue 2, Page 248-263, April 2024.
Estimating the migratory patterns of Ommastrephidae based on remote sensing is attractive and challenging; recorded jiggers do not chase a certain group of individuals (like tagging‐based tracking) but catch individuals in different ages and migration stages.

Performance Parameters of Paralarvae and Postparalarvae Rearing of Patagonian Red Octopus, Enteroctopus megalocyathus, under Experimental Conditions

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
Patagonian red octopus, Enteroctopus megalocyathus, an interesting species for Chilean aquaculture diversification, requires the improving of their experimental technology to obtain early juveniles. The first objective of the study was to enhance aspects of feeding and temperature management in broodstock, egg incubation, paralarvae rearing, and early ...

Regulation of growth-related genes by nutrition in paralarvae of the common octopus (Octopus vulgaris)

open access: yes, 2020
The common octopus (Octopus vulgaris) is a species of great interest to the aquaculture industry. However, the high mortalities registered during different phases of the octopus lifecycle, particularly the paralarvae stage, present a challenge for ...
