J. mar. biol. Ass. U.K. (1958) 37, 7°5-752 Printed in Great Britain OBSERVATIONS ON LUMINESCENCE IN PELAGIC ANIMALS By J. A. C. NICOL The Plymouth Laboratory (Plate I and Text-figs. 1-19) Luminescence is very common among marine animals, and many species possess highly developed photophores or light-emitting organs. It is probable, therefore, that luminescence plays an important part in the economy of their lives. A few determinations of the spectral composition and intensity of light emitted by marine animals are available (Coblentz & Hughes, 1926; Eymers & van Schouwenburg, 1937; Clarke & Backus, 1956; Kampa & Boden, 1957; Nicol, 1957b, c, 1958a, b). More data of this kind are desirable in order to estimate the visual efficiency of luminescence, distances at which luminescence can be perceived, the contribution it makes to general back• ground illumination, etc. With such information it should be possible to discuss. more profitably such biological problems as the role of luminescence in intraspecific signalling, sex recognition, swarming, and attraction or re• pulsion between species. As a contribution to this field I have measured the intensities of light emitted by some pelagic species of animals. Most of the work to be described in this paper was carried out during cruises of R. V. 'Sarsia' and RRS. 'Discovery II' (Marine Biological Association of the United Kingdom and National Institute of Oceanography, respectively). Collections were made at various stations in the East Atlantic between 30° N. and 48° N. The apparatus for measuring light intensities was calibrated ashore at the Plymouth Laboratory; measurements of animal light were made at sea. -

Their trophic function in the ocean, as well as their ecology and physiology in general, are extremely poorly known. During the ANTARES-4 survey (January and February 1999) their feeding dynamics were investigated in the south Indian Ocean. Results show that their in situ clearance rates may be among the highest recorded in any pelagic grazer, with up to 35 l h–1 per colony (length: 17.9 ± 4.3 [SD] cm). Gut pigment destruction rates, estimated for the first time in this tunicate group, are higher than those previously measured in salps and appendiculari- ans, ranging from 54 to virtually 100% (mean: 79.7 ± 19.8%) of total pigment ingested. Although individual colony ingestion rates were high (39.6 ± 17.3 [SD] µg –1 The pelagic tunicate Pyrosoma atlanticum conducts diel pigment d ), the total impact on the phytoplankton vertical migrations.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
Fisheries Laws and Regulations in the Mediterranean; a Comparative Study
GENERAL FISHERIES COMMISSION FOR THE MEDITERRANEAN ISSN 1020-9549 STUDIES AND REVIEWS No. 75 2005 In 2001, a study on the fisheries regulatory framework of the western Mediterranean coastal states FISHERIES LAWS AND REGULATIONS IN THE was undertaken under the aegis of the CopeMed Project. In 2002, the AdriaMed Project undertook a similar study covering the Adriatic coastal states. As a follow-up, the Secretariat of the General MEDITERRANEAN: A COMPARATIVE STUDY Fisheries Commission for the Mediterranean (GFCM) commissioned a parallel study with the support of the FishCode Programme covering the eastern Mediterranean. These exercises provided the basis for the present comparative study, which covers the entire Mediterranean basin and focuses on three main issues: (i) access regimes to fisheries resources; (ii) management of fishing effort and fishing capacity; and (iii) monitoring, control and surveillance. Preliminary reference is also made to recreational fishing. The purpose of this study is to provide fisheries managers with information on the principal fisheries management measures adopted in the region and thereby to identify areas where harmonization should be sought, particularly in relation to shared stocks. Conceived as a working document, this study should be regularly updated. In this respect, at its seventh session in 2004, the Scientific Advisory Committee of GFCM suggested that Members inform the Secretariat of the enactment of any new law or regulation, or amendment of texts in force. ������������������ �������������� � -

Distribution, Associations and Role in the Biological Carbon Pump of Pyrosoma Atlanticum (Tunicata, Thaliacea) Off Cabo Verde, N
www.nature.com/scientificreports OPEN Distribution, associations and role in the biological carbon pump of Pyrosoma atlanticum (Tunicata, Thaliacea) of Cabo Verde, NE Atlantic Vanessa I. Stenvers1,2,3*, Helena Hauss1, Karen J. Osborn2,4, Philipp Neitzel1, Véronique Merten1, Stella Scheer1, Bruce H. Robison4, Rui Freitas5 & Henk Jan T. Hoving1* Gelatinous zooplankton are increasingly acknowledged to contribute signifcantly to the carbon cycle worldwide, yet many taxa within this diverse group remain poorly studied. Here, we investigate the pelagic tunicate Pyrosoma atlanticum in the waters surrounding the Cabo Verde Archipelago. By using a combination of pelagic and benthic in situ observations, sampling, and molecular genetic analyses (barcoding, eDNA), we reveal that: P. atlanticum abundance is most likely driven by local island- induced productivity, that it substantially contributes to the organic carbon export fux and is part of a diverse range of biological interactions. Downward migrating pyrosomes actively transported an estimated 13% of their fecal pellets below the mixed layer, equaling a carbon fux of 1.96–64.55 mg C m−2 day−1. We show that analysis of eDNA can detect pyrosome material beyond their migration range, suggesting that pyrosomes have ecological impacts below the upper water column. Moribund P. atlanticum colonies contributed an average of 15.09 ± 17.89 (s.d.) mg C m−2 to the carbon fux reaching the island benthic slopes. Our pelagic in situ observations further show that P. atlanticum formed an abundant substrate in the water column (reaching up to 0.28 m2 substrate area per m2), with animals using pyrosomes for settlement, as a shelter and/or a food source. -

PYROSOMA.—A TAXONOMIC STUDY, BASED UPON THE COLLECTIONS OF THE UNITED STATES BUREAU OF FISHERIES AND THE UNITED STATES NATIONAL MUSEUM. By Maynard M. Metcalf and Hoyt S. Hopkins, Oj Oberlin, Ohio. INTRODUCTION. The family Pyrosomidae is generally regarded as containing but one genus Pyrosoma. There are, however, two very distinct groups in the family, the Pyrosomata ambulata and the Pyrosomata Jlxata, which might as properly be regarded as two separate genera. In this paper we are treating them as subgenera, although it would be equally well to give each group its own generic name. The members of the family all have the form of free swimming, tubular colonies, and they all emit a strong phosphorescent light. They are said to be the most brilliantly luminous of all marine organisms. Pijrosorna was first described by Peron (1804), and was later more thoroughly studied by Lesueur (1815). The earlier specimens known came from the Atlantic Ocean and Mediterranean Sea, but many have since been collected from all seas, with the exception of the Arctic Ocean. About sixteen species and varieties are now known, including the new forms described in this paper, whereas previous to the year 1895 only three had been described. In that year appeared Seeliger's memoir, "Die Pyrosomen der Plankton Expedition," and this was followed by important memoirs by Neumann and others upon collec- tions made by different oceanographic expeditions. The anatomy, embryology, and budding have been well studied, but little is known of the behavior of the living animals or of their physiology. Our studies are based upon the remarkably rich collections of the United States Fisheries Steamer Albatross in Philippine waters during the years 1908 and 1909 and upon the extensive collections in the United States National Museum, made almost wholly by vessels of the United States Bureau of Fisheries, chiefly the steamer Albatross, which since 1883 has been almost continuously engaged in oceano- graphic studies. -
