Scalpay Video Survey 2015 Scalpay Video Survey 2015 11.02.2016 Revised( 12.05.2017) Registered in Scotland No. 138843 Stob Ban House, Glen Nevis Business Park 01397 715084 - Registered Office, Fort William, Scotland PH33 6RX 1st Floor, Admiralty Park Admiralty Road Rosyth Stob Ban House, Glen Nevis Business Park Fife Fort William, Scotland KY11 2YW PH33 6RX http:// marineharvest. com Scalpay Video Survey 2015 On the 20th of August 2015, a video survey was carried out at Scalpay. The survey consists of 3 transects, which have been labelled T1, T2 & T3. T1 is approximately 728mtrs long and runs in a North to South direction. T2 is approximately 370mtrs long and runs in an East to West direction, crossing over the Northern half of T1. T3 is approximately 323mtrs long and runs in a general East to West direction, crossing over the Southern half of T1. Due to the length of transects two intermediate points were created, Inter 1 & Inter 2. Inter 1 is at the crossover point of T1 & T2, while Inter 2 is at the crossover point of T1 & T3. The intermediate points were used as starting positions for the ROV to dive from, this allowed the survey to be carried out with less umbilical in the water, decreasing the drag on the ROV & reducing the potential for getting caught on any subsea obstructions. The ROV’s position during each dive was logged via a GPS/ USBL tracking system to ensure the accuracy of the data. An Image of transects and exact camera path for each dive can be found below (Figure 1 & 2).

  • Fine Structure of the Podia in Three Species of Paxillosid Asteroids of the Genus Lu/Dia (Echinodermata)
    Belg. J. Zool. - Volume 125 (1995) - issue 1 - pages 125-134 - Brussels 1995 FINE STRUCTURE OF THE PODIA IN THREE SPECIES OF PAXILLOSID ASTEROIDS OF THE GENUS LU/DIA (ECHINODERMATA) by PATRICK FLAMMANG * La boratoire de Biologie Marine, Université de Mons-Hainaut, 19 av. Maistriau, B-7000 Mons, Belgium SUMMARY lndividuals of the paxillosid asteroid genus Luidia use their podia in locomotion a nd burrowing. Each podium in the three considered species consists of a stem wi tb a pointed knob at its tip. The knob consists of four tissue layers that are, from the inside to the outside, a mesothelium, a connective ti ss ue layer, a nerve plexus, and an epidermis. The latter is made up of four cell categories : secretory cells, neurosecretory cells, non-secretory cili ated cell s, and support cells. The epidermal cells of the podial knob are presumabl y fun ctioning as a duo­ gland adhesive system in which adhesive secretions would be produced by secretory cell s wh ile de-adhesion, on the other band, would be due to neurosecretory cell secretions. Although the podia of the three considered species of Luidia share numerous simjlarities, there are nevertheless severa! important morphological differences between, on the one band, the podia of L. ciliaris and L. maculata, and, on the other band, the podia of L. penangensis. These dif­ ferences stress that carefulness is required when ge n e r a lj zat ion ~, drawn from the morphology of a single species, are applied to related species havin g the sa me ]jfe style ; but also that the gem1s Luidia needs to be re-exa mined from a taxonomjc p-o int of view.

  • The Reproductive System and Associated Organs of the Brittle-Star Ophiothrix Fragilis

The observations which are recorded in this paper are the outcome of an investigation directed, primarily, towards the interpretation of the morphology and histology of the nervous system of the ophiuroid Opldothrix fragilis, Abildgaard. During the course of the work opportunity was afforded for examination of large numbers of brittle-stars ranging from post- metamorphic individuals to fully mature specimens, the sizes being of a disc diameter of 0-4 to 16 mm. Prom observations made on living animals and by the examination of sectioned material it has been possible to obtain information relating to the morphology and development of the organs assoeiatedj either directly or indirectly, -with reproduction. The systems of organs described include the gonads, the gonodncts, the axial organ and related sinuses, the genital rachis and the 268 J. E. SMITH genital bursae. Some explanation of the inclusion of the axial organ complex, which is not primarily associated with the reproductive system, in this account is, perhaps, due. Two reasons may be given. The first is that the axial organ and the genital rachis, though of different origin, are in close association during development and throughout adult life, and the second is that the interpretation of the morphology of the axial organ complex, here given, is in close agreement with that of Fedotov (1924) who, in ascribing a double origin and structure to the axial organ and sinus system of Opbiuroids, is in disagreement with all earlier investigators of the problem.

  • The Marine Fauna of Lundy Ecidnodermata
    Rep. Lundy Fld Soc. 29 (1978) THE MARINE FAUNA OF LUNDY ECIDNODERMATA P. A. TYLER Department of Oceanography, University College, Swansea, S. Wales, U.K. INTRODUCTION The five classes of echinoderms are a conspicuous element of the fauna in truly marine areas. The British echinoderm fauna has been treated in detail by Mortensen (1927). In shelf sea areas they are usually found below LWN tide level with occasional species moving up into the littoral zone. Examples of the dominant extant groups are found in all types of substrates, the ophiuroids and the heart urchins being particularly important in the determination of soft substrate benthic communities (Thorson, 1947). SOURCES OF MATERIAL The collections made by divers during marine surveys of Lundy have pro­ duced a considerable record particularly of the conspicuous epifaunal asteroids, regular echinoids and holothurians. Observations of the less conspicuous in­ faunal ophiuroids and irregular echinoids have been obtained by divers and by benthic surveys using R.V. 'Ocean Crest'. THE LUNDY FAUNA- GENERAL CONSIDERATIONS To date, 24 species of echinoderm have been recorded around Lundy. Of these species only 8 were recorded by Harvey (1950, 1951) at Lundy. The most noteable exceptions to the fauna are Acrocnida brachiata and Spatangus purpureus, both of which have been found further up the Bristol Channel and may be supposed to be found round Lundy where a suitable substrate exists for these infaunal species. A number of species appear to be common all round the island. These include Asterias rubens, Marthasterias glacia/is, Luidia ciliaris, Echinus esculentus and Holothuria forskali. The very rare sea cucumber Lepto­ synapta decaria has been reported as occurring round Lundy (Hoare & Wilson, 1976).

Vea Salvanes Institute of Marine Research, Bergen, Norway ABSTRACT As a contribution to a research program on sea·ranching of cod in a fjord in western Norway, a dietary analysis of the main gadoid species has been conducted. The main aim of the analysis has been to identify potential predators and competitors to the young cod which will be released. Stomachs of the gadoid species cod (~. morhua), pollack (R. pollachius), saithe (g.virens), and poor-cod (I. minutus) were collected during monthly experimental fishing, June-85 - July-86. The gobies Pomatochistus minutus and Gobisculus flavesenc are found to be important food items of all the Gadidae examined. The smallest length groups of all four species tend to overlap in diet, and one conclusion reached is that an extended analysis should include investigations of the four Gadidae caught at the same place and time together with an examination of the prey species, among which gobies should be given special attention. Cod is found to feed canibalistically, and pollack is found to be an important predator to cod. A second conclusion is therefore that a more detailed study of the abundance and distribution of pollack is needed. 2 ··: 1. INTRODUCTION As a contribution to a research program on sea ranching of cod in Masfjorden, a fjord in western Norway, a comparative study of the diet of the major gadoid speci~s is being t6nd~ct~d.
