Overfishing of Small Pelagic Fishes Increases Trophic Overlap Between Immature and Mature Striped Dolphins in the Mediterranean Sea
Overfishing of Small Pelagic Fishes Increases Trophic Overlap between Immature and Mature Striped Dolphins in the Mediterranean Sea Encarna Go´ mez-Campos1*, Assumpcio´ Borrell1, Luis Cardona1, Jaume Forcada2, Alex Aguilar1 1 Department of Animal Biology-Vertebrates, Institute of Biodiversity Research, Faculty of Biology, University of Barcelona, Barcelona, Spain, 2 British Antarctic Survey, Natural Environment Research Council, Cambridge, United Kingdom Abstract The interactions among diet, ecology, physiology, and biochemistry affect N and C stable isotope signatures in animal tissues. Here, we examined if ecological segregation among animals in relation to sex and age existed by analyzing the signatures of d15Nandd13C in the muscle of Western Mediterranean striped dolphins. Moreover, we used a Bayesian mixing model to study diet composition and investigated potential dietary changes over the last two decades in this population. For this, we compared isotope signatures in samplesofstrandeddolphinsobtainedduringtwoepizootic events occurring in 1990 and 2007–2008. Mean d13C values for females and males were not significantly different, but age-related variation indicated d13C enrichment in both sexes, suggesting that females and males most likely fed in the same general areas, increasing their consumption of benthic prey with age. Enrichment of d15Nwasonlyobserved in females, suggesting a preference for larger or higher trophic level prey than males, which could reflect different nutritional requirements. d13C values showed no temporal variation, although the mean d15Nsignaturedecreased from 1990 to 2007–2008, which could indicate a dietary shift in the striped dolphin over the last two decades. The results of SIAR indicated that in 1990, hake and sardine together contributed to 60% on the diet of immature striped dolphins, and close to 90% for mature striped dolphins. -
CEPHALOPODS A3a.3.1 Introduction
Offshore Energy SEA A3a.3 CEPHALOPODS A3a.3.1 Introduction This section describes the biology and ecology of the main cephalopod species found within UK waters. Cephalopods are short-lived, carnivorous invertebrates with rapid growth rates that play an important role in marine food webs. Two superorders of the class Cephalopoda are found within the area: the Decapodiformes (squid and cuttlefish) and the Octopodiformes (octopuses). Most cephalopods lack an external shell and are highly mobile predators. They possess complex eyes, similar to those of vertebrates and are often regarded as the most intelligent of invertebrates. The importance of cephalopod stocks to commercial fisheries is increasing, as fish stocks dwindle and become subject to tighter management (Boyle & Pierce 1994). Much of the work carried out on cephalopod distributions and abundances in UK waters is based on landings data and routine research vessel surveys co- ordinated by ICES. Information on the life history, distribution and abundance of these species has been taken from a review of UK cephalopods produced by Hastie et al. (2008), unless otherwise cited. An overview of important cephalopod species in UK waters is provided, followed by a brief description of features specific to each Regional Sea. A3a.3.2 UK context A number of species occur in UK waters, with varying degrees of frequency. Most cephalopods will be in one of five groups: the long-finned squids (Lolignids), the short-finned squids (Ommastrephids), bobtails (Sepiolids), cuttlefish and octopuses. Among the most frequently recorded species are: the long-finned squids, Alloteuthis subulata and Loligo forbesii; the short finned squid, Todarodes sagittatus; other squids, Gonatus fabricii and Onychoteuthis banksii; the bobtail squids, Rossia macrosoma, Sepiola atlantica and Sepietta oweniana; the octopus, Eledone cirrhosa. -

Feeding Habits of Neon Flying Squid Ommastrephes Bartramii in the Transitional Region of the Central North Pacific
MARINE ECOLOGY PROGRESS SERIES Vol. 266: 173–184, 2004 Published January 30 Mar Ecol Prog Ser Feeding habits of neon flying squid Ommastrephes bartramii in the transitional region of the central North Pacific Hikaru Watanabe1,*, Tsunemi Kubodera2, Taro Ichii1, Shigeyuki Kawahara1 1National Research Institute of Far Seas Fisheries, 5-7-1 Orido Shimizu, Shizuoka 424-8633, Japan 2National Science Museum, 3-23-1 Hyakunin-cho Shinjyuku, Tokyo 169-0073, Japan ABSTRACT: We examined the feeding habits of the neon flying squid Ommastrephes bartramii from late spring to mid-summer in relation to its northward migration in the transitional waters of the cen- tral North Pacific. The winter–spring cohort (ca. 15 to 25 cm in May and 20 to 35 cm in July) and the autumn cohort (ca. 30 to 45 cm in May and 35 to 50 cm in July) were identified by their dorsal man- tle lengths. In May and July, the winter–spring cohort was distributed only in the transition zone (TZ) south of the subarctic boundary. This cohort preyed primarily on crustaceans such as euphausiids and amphipods in May, but in July, their primary prey shifted to the sternoptychid fish Maurolicus imper- atorius. In May, the larger-sized autumn cohort was also distributed only in the TZ, but in July, these individuals migrated to the transitional domain (TD) north of the subarctic boundary. The main prey of the autumn cohort were micronektonic animals that dominated the TZ in May: the transitional- water myctophid Symbolophorus californiensis, and 2 subtropical myctophids, Ceratoscopelus warm- ingi and Electrona risso. Secondary important prey items included the transitional-water squid Onychoteuthis borealijaponica and subarctic gonatid squids such as Gonatus berryi and Berryteuthis anonychus. -

Offshore Energy SEA 3: Appendix 1 Environmental Baseline A1a.3 Cephalopods A1a.3.1 UK context This section describes the biology and ecology of the main cephalopod species found within UK waters. Cephalopods are short-lived, carnivorous invertebrates with rapid growth rates that play an important role in marine food webs. Two superorders of the class Cephalopoda are found within the area: the Decapodiformes (squid and cuttlefish) and the Octopodiformes (octopuses).

Todarodes Sagittatus) in North Norwegian Wale
NAFO SCI. Coun. Studies, 9: 125-132 Predatory R of the Flying Squid (Todarodes sagittatus) in North Norwegian Wale Anne Breiby and Malcolm Jobling Institute of Fisheries, University of Troms¢ N-9001 Troms¢, Norway Abstract Analysis of the gut contents of Todarodes sagittatus were carried out from samples which were obtained by jigging in coastal waters of northern Norway. The food was comprised predominantly of pelagic species, with polychaetes, crustaceans and fish being the major prey groups. Feeding indices provided evidence of a size-related shift in dietary composition, with increased reliance on fish prey as the squid increase in size. Use of otolith size-fish size relationships to estimate prey size indicated that the range of prey size increased with squid growth. The presence of relatively undigested pieces of squid in the gut contents was interpreted as being an artefact of the fishing technique, and it is suggested that the importance of cannibalism may have been overevaluated in other studies on the feeding habits of squids. The ways in which choice of sampling and analytical techniques may influence the results of dietary studies are discussed. I ntrodl.lction Materials and Methods Although the European flying squid (Todarodes Samples of T. sagittatus were collected at various sagittatus) is thought to occupy a key position in the times from October 1982 to October 1983. Although it food web of Arctic regions in the Northeast Atlantic, would have been desirable to have collected the sam comparatively little is known about its feeding biology, ples at one specific location, movements and availabil with the majority of available information being widely ity of squid made this impossible, Consequently, the scattered, unsystematic lists of the types of food orga samples were taken at several locations along the nisms (Wiborg, 1972, 1978,1979,1980,1981; Jonsson, north coast of Norway between Andenes and Kam(by 1980). -
A Gap Analysis of the Distributions of Cephalopod Species Worldwide with a Focus on Commercially Important Species
A Gap Analysis of the Distributions of Cephalopod Species Worldwide with a Focus on Commercially Important Species Alexandra Stikas Fries Abstract Cephalopods are valuable species as they provide ecological functions and are also important commercially and scientifically. This study attempts to adequately describe the distribution of Class Cephalopoda as well as focusing on a few commercial species ranges. Data from an extensive literature search and several databases such as OBIS and AquaMaps were analyzed to show areas where information is lacking due to no research conducted in the area versus where literature research is excluded from OBIS. For the species distributions modeled in AquaMaps, an accuracy assessment was performed to show if all of the locations where the species have been found would be included within the suspected range. Recommendations for more research or greater conservation actions will also be given for each of the commercial species examined. Fisheries data on the commercial species will be compared to the distributional extents to show where better management practices might be needed. Introduction The cephalopod class is a fascinating and diverse set of species that are important biologically, commercially and scientifically. They exist in all marine habitats worldwide and provide a large part of the total global biomass of all marine species (Clarke, 1996). Scientific knowledge of cephalopod distributions and abundances is important to understand their contribution not only to ecological relationships but also to overall energy flow and transfer of materials (Piatkowski et al. 2001). Overall, cephalopod species have been mostly ignored in the past and thought of as being a disturbance and useless bycatch.
