The new information reported in this paper is based on five maturing and mature females of the large-tuberculate octopus Graneledone macrotyla. These specimens were caught in bottom trawl surveys ATLANTIS 2009 (February 24 to April 1, 2009) and ATLANTIS 2010 (March 9 to April 5, 2010) carried out off the Argentinean Economic Exclusive Zone. Capture depth ranged from 475 to 921 m and sea bottom temperature between 2.8 and 3.1 °C. Development of the complex ovary, oviducts, and oviducal glands…

Histomorphological study of ovarian atresia over the reproductive cycle of Octopus vulgaris from Galician waters (NW Spain)
Given the pattern of atresia, the reproductive strategy of this species is based on an asynchronic ovary development and a synchronous ovulation during spawning and potential fecundity for this species should be measured on late vitellogenic oocytes in pre-spawning females.
Erratum to: Histomorphological study of ovarian atresia over the reproductive cycle of Octopus vulgaris from Galician waters (NW Spain)
Atresia has been poorly examined in cephalopods. We here provide a histological description of this process along the whole ovary development for Octopus vulgaris. Additionally, we related its
The development process and seasonal changes of the gonad in Octopus ocellatus Gray off the coast of Qingdao, Northeast China
This work contributes to the understanding of the maturation process in O. ocellatus, laying a foundation for further study on the mechanism of sperm storage in female octopuses and providing a reference for artificial breeding and fisheries impact assessment of this species.
Oviducal glands throughout the gonad development stages: a case study of Octopus mimus (Cephalopoda)
Structural changes of each section of the ODG of Octopus mimus are described histologically throughout the gonad development stages (GDS), which complements the GDS and provides better reproductive status assessment.

This review summarizes the sperm storage methods and the mechanisms of post-copulatory sexual selection in cephalopods and it is proposed that these diverse methods evolved as adaptive mechanisms through post-CopulatorySexual selection.
Report of the Working Group on Cephalopod Fisheries and Life History (WGCEPH)
The two-stage biomass model currently used for cuttlefish stock assessment in the English Channel is implemented into a Bayesian framework and compared the results with the outputs of the initial fit, finding similar trends of biomass estimates for both models.


New insights into the morphology, reproduction and distribution of the large-tuberculate octopus Graneledone macrotyla from the Patagonian slope
The simultaneous occurrence of oocyte cohorts at different oogenic stages suggests that the large-tuberculate octopus Graneledone macrotyla is a multiple spawner.
It was shown that the process of the oocyte development in the gonad and number of oogenetic stages in L. gahi are similar to those described before in a number of temperate loliginid species, however, development of both yolkless and vitellogenic oocytes is shifted to the earlier stages of the reproductive system maturation.
Reproductive biology in two species of deep-sea squids
The data and the literature data show that the so-called “synchronous ovulation” probably occurs in all deepwater squids.
Signs of multiple spawning in Graneledone pacifica (Cephalopoda: Octopodidae)

The examination of five females of the deep-benthic octopus Graneledone pacifica showed that their developing oocyte size-distribution was normal in two specimens at an early maturation stage, bimodal in three specimens at a more advanced stage, and three-modal in the farthest advanced stage specimen.
Fecundity, Atresia, and Egg Size of Captive Atlantic Cod (Gadus morhua) in Relation to Proximate Body Composition
The depletion of the white muscle and liver was related to oocyte maturation and in particular to the proportion of eggs spawned (PES), and the influx of protein into the ovary, the mean hydrated egg diameter, and the egg dry weight all reached maximum values at 10% PES and subsequently declined.
A contribution to the reproductive biology and geographical distribution of Antarctic Octopodidae (Cephalopoda)
From the large variation of the gonad index and the size/frequency distribution of ova as well as from the morphology of gonads, there was evidence that spawning in mid March had already commenced.
Egg brooding by deep-sea octopuses in the North Pacific Ocean.
Videotapes made from the submersible Alvin on Baby Bare and at two other deep-sea localities document that octopuses of the genera Graneledone and Benthoctopus attach their eggs to hard substrate and apparently brood them through development.
Female reproductive biology of two sympatric incirrate octopod species, Adelieledone polymorpha (Robson 1930) and Pareledone turqueti (Joubin 1905) (Cephalopoda: Octopodidae), from South Georgia
The reproductive biology of two species of endemic Southern Ocean octopods was investigated around the sub-Antarctic islands of South Georgia and Shag Rocks and it is possible that both species could have either a single or multiple-batch spawning strategy.
Aggregations of Egg-Brooding Deep-Sea Fish and Cephalopods on the Gorda Escarpment: a Reproductive Hot Spot
A unique multispecies reproductive aggregation located on the Gorda Escarpment, California is described, document some of the highest fish and octopus densities ever reported in the deep sea, and highlight how physical and bathymetric heterogeneity in the environment can result in reproductive hot spots, which may be a critical resource in some deep-sea species.
An Investigation of the Egg Distribution of the Chokka Squid, Loligo Vulgaris Reynaudii, in Krom Bay, South Africa
Part of the spawning area of the squid, Loligo vulgaris reynaudii, was investigated over a 5-week period using a combination of hydroacoustic techniques, SCUBA dive transects and observations, and two statistical techniques were used in an exploratory data analysis.
