Infor- mation on the status of fished stocks and fisheries (ToR A) was updated based on previ- ously compiled information updated with new information provided in response to a data call. Cephalopod landings from the Northeast Atlantic in 2016 were 30% higher than the 2000–2015 average, mainly due to high yields of octopuses and short-finned squid. New information on assessment and management was compiled and plans for a manu- script on stock trends were discussed (ToR B). A new empirical model to predict octopus abundance in the Gulf of Cadiz, using survey abundance and hydro-climatic variables, was presented. Limitations of available information were discussed and it is noted that lack of reliable species identification remains an issue both for almost all commercial data and data from many surveys. A new review of life history information on fished cephalopods in the ICES area was assembled (ToR C). The group reviewed around 200 journal articles on life history, dis- tribution, trophic relationships, taxonomy, fisheries and impact of climate change on cephalopods published during the last five years (2013–2017). Some new information on the economic and social importance of cephalopod fisheries was compiled and progress with a planned manuscript on socioeconomic aspects of cephalopod fisheries was dis- cussed (ToR D). Information on approximately 30 existing cephalopod identification guides was compiled and specifications were drawn up for a new ID sheets for use during research surveys and for sampling of commercial catches (ToR E). The WGCEPH 2018 meeting will be hosted by AZTI (Spain), San Sebastian, Spain, June 2018. 4 | ICES WGCEPH REPORT 2017 1 Administrative details Working Group name Working Group on Cephalopod Fisheries and Life History (WGCEPH) Year of Appointment within current cycle 2017 Reporting year within current cycle (1, 2 or 3) 1 Chair(s) Graham J.

  • <I>Todaropsis Eblanae</I>
    BULLETIN OF MARINE SCIENCE, 71(2): 711–724, 2002 RECRUITMENT, GROWTH AND REPRODUCTION IN TODAROPSIS EBLANAE (BALL, 1841), IN THE AREA FISHED BY FRENCH ATLANTIC TRAWLERS J. P. Robin, V. Denis, J. Royer and L. Challier ABSTRACT Short-finned squid landed by the French fishery are by-catch of trawlers operating in the Northern Bay of Biscay and Southern Celtic sea. In the period November 1997–June 1999 samples of commercial specimen were collected monthly. A total 1065 Todaropsis eblanae were analysed for biological parameters. In a subsample of animals age was determined using statoliths. Mature animals are observed almost all year round, however juvenile recruitment occurred mainly in winter and sexual maturation increased in spring. Size at sexual maturity (DML50) was 16.5 cm in females and 13.5 cm in males. Length frequencies showed that the range of exploited stages was 9–29 cm in females and 8–22 cm in males. Statolith analysis indicated that youngest recruits were about 4 mo old and that growth was faster in females than in males (3.41 and 1.86 cm mo−1, respectively). Sex-related differences in growth and size at maturity are in agreement with previously published data from the Galician coast. Todaropsis eblanae (Ball, 1841) is an oceanic squid, which lives near the bottom on the shelf break. In the Mediterranean, it has been observed at depths between 200 and 600 m in the Western area (Quetglas et al., 2000) and in shallower waters in the Central and Eastern areas (Belcari and Sartor, 1993; Tursi and D’Onghia, 1992).

  • <I>Sthenoteuthis Oualaniensis</I>
    BULLETIN OF MARINE SCIENCE, 71(2): 1105–1108, 2002 THE AGE AND GROWTH OF STHENOTEUTHIS OUALANIENSIS (CEPHALOPODA: OMMASTREPHIDAE) IN THE PACIFIC OCEAN Kaori Takagi, Takeru Kitahara, Naoki Suzuki, Junta Mori and Akihiko Yatsu Sthenoteuthis oualaniensis is distributed in the tropical and subtropical areas of the Pacific and the Indian Oceans. According to Nesis (1993), there is a complex population structure in S. oualaniensis, as is the case in many other ommastrephids and some loliginids. In the Pacific Ocean, there is the middle-sized squid which is a widespread and typical one (Nesis, 1993). Arkhipkin and Bizikov (1991) examined the statoliths of middle-sized female in the Indian Ocean and determined its growth. S. oualaniensis is, though, one of the most difficult species in the Ommastrephidae for the observation of statolith incre- ments due to the numerous occulting crystals and weak contrast in the increments (Uozumi, 1993). Using a newly developed heating technique in processing statoliths, we estimated the age and growth of S. oualaniensis, assuming the daily deposition of increments. MATERIALS AND METHODS Samples of S. oualaniensis were collected between September and December 1993 in the Pa- cific Ocean around the Hawaii and the Ogasawara (Bonin) Islands. We used the statoliths of 53 adults (112–284 mm in mantle length (ML), 21 males and 32 females) and 112 paralarvae (0.7– 13.5 mm in ML). The adults were captured by drift nets and jigs. The paralarvae were captured by bongo nets and a larval net. To examine the relationship between ML and age, we also used 6 other juveniles (39–50 mm in ML) captured using a dip net.

  • Helminth Infection in the Short-Finned Squid Illex Coindetii (Cephalopoda, Ommastrephidae) Off NW Spain
    DISEASES OF AQUATIC ORGANISMS Published September 14 Dis aquat Org Helminth infection in the short-finned squid Illex coindetii (Cephalopoda, Ommastrephidae) off NW Spain 'Laboratorio de Parasitologia, Facultad de Ciencias, Universidad de Vigo, Ap. 874 E-36200 Vigo, Spain 'Institute de Investigacions Marinas (CSIC),Eduardo Cabello 6, E-36208 Vigo, Spain ABSTRACT: A survey of parasites in 600 short-finned squid fllex coindetii (Verany. 1839) taken from 2 locations (north and south Galicia) off the northwestern Ibenan Peninsula revealed the presence of numerous somatoxenous helrninths. Three genera of Tetraphyllidean plerocercoids were represented (prevalences: Ph}~llobothriurn sp., 45.7%; Dinobothriunl sp., 0.8%; and Pelichnibothrium speciosum, 0.001 %); 1 Trypanorhynchidean metacestode was also present (Nybelinia vamagutll. 0.4 %). In addi- tion, larval nematodes of Anisakis simplex (L3) were recorded (10.6%). Abundance of infection was examined in relation to squid sex, standard length, maturity and locality. This analysis indicated that parasite infection was lower in the southern squids than in the northern squid group. Over the entire survey area, parasite infection showed a close positive correlation with host life-cycle, often with the greatest number of parasites among the largest and highest maturity individuals (>l8to 20 cm; matu- rlty stage V).

  • Spermatophore Transfer in Illex Coindetii (Cephalopoda: Ommastrephidae)
    Spermatophore transfer in Illex coindetii (Cephalopoda: Ommastrephidae) TREBALL DE FI DE GRAU GRAU DE CIÈNCIES DEL MAR EVA DÍAZ ZAPATA Institut de Ciències del Mar (CSIC) Universitat de Barcelona Tutors: Fernando Ángel Fernández-Álvarez i Roger Villanueva 05, 2019 RESUMEN CIENTÍFICO La transmisión de esperma desde el macho a la hembra es un proceso crítico durante la reproducción que asegura la posterior fecundación de oocitos. Durante el apareamiento, los machos de los cefalópodos incrustan en el tejido de la hembra paquetes de esperma denominados espermatóforos mediante un complejo proceso de evaginación conocido como reacción espermatofórica. Estos reservorios de esperma incrustados en el cuerpo de la hembra se denominan espermatangios. En este estudio se han analizado machos y hembras maduros de Illex coindetii recolectados desde diciembre del 2018 hasta abril del 2019 en la lonja de pescadores de Vilanova i la Geltrú (Mediterráneo NO). El objetivo de este estudio es entender cómo se produce la transmisión de los espermatóforos en esta especie carente de órganos especiales para el almacenamiento de esperma (receptáculos seminales). En los ejemplares estudiados se cuantificó el número de espermatóforos y espermatangios y mediante experimentos in vitro se indujo la reacción espermatofórica para describir el proceso de liberación del esperma. Los resultados han demostrado que los machos maduros disponen entre 143 y 1654 espermatóforos y las hembras copuladas presentan entre 35 y 668 espermatangios en su interior. La inversión reproductiva en cada cópula realizada por los machos oscila entre el 2 y el 40 % del número de espermatóforos disponibles en un momento dado. En experimentos realizados in vitro, la reacción espermatofórica se inicia espontáneamente tras entrar el espermatóforo en contacto con el agua de mar.

  • Defensive Behaviors of Deep-Sea Squids: Ink Release, Body Patterning, and Arm Autotomy
    Defensive Behaviors of Deep-sea Squids: Ink Release, Body Patterning, and Arm Autotomy by Stephanie Lynn Bush A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in Charge: Professor Roy L. Caldwell, Chair Professor David R. Lindberg Professor George K. Roderick Dr. Bruce H. Robison Fall, 2009 Defensive Behaviors of Deep-sea Squids: Ink Release, Body Patterning, and Arm Autotomy © 2009 by Stephanie Lynn Bush ABSTRACT Defensive Behaviors of Deep-sea Squids: Ink Release, Body Patterning, and Arm Autotomy by Stephanie Lynn Bush Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair The deep sea is the largest habitat on Earth and holds the majority of its’ animal biomass. Due to the limitations of observing, capturing and studying these diverse and numerous organisms, little is known about them. The majority of deep-sea species are known only from net-caught specimens, therefore behavioral ecology and functional morphology were assumed. The advent of human operated vehicles (HOVs) and remotely operated vehicles (ROVs) have allowed scientists to make one-of-a-kind observations and test hypotheses about deep-sea organismal biology. Cephalopods are large, soft-bodied molluscs whose defenses center on crypsis. Individuals can rapidly change coloration (for background matching, mimicry, and disruptive coloration), skin texture, body postures, locomotion, and release ink to avoid recognition as prey or escape when camouflage fails. Squids, octopuses, and cuttlefishes rely on these visual defenses in shallow-water environments, but deep-sea cephalopods were thought to perform only a limited number of these behaviors because of their extremely low light surroundings.
