Notes on Starfish on an Essex Oyster Bed
J. mar. biol. Ass. U.K. (1958) 37, 565-589 Printed in Great Britain NOTES ON STARFISH ON AN ESSEX OYSTER BED By D. A. HANCOCK Fisheries Laboratory, Burnham-on-Crouch (Text-figs. 1-9) In a previous paper (Hancock, 1955) an account was given of the feeding behaviour of the starfish Asterias rubens L. and the common sunstar Solaster papposus (L.) on Essex oyster beds. In discussion, it was stated that there was no evidence that, in the conditions described, a cultivated oyster ground provided a greater attraction than an uncultivated one. The present work was undertaken to provide information on this subject, and also on the movements, growth and ecological relationships of starfish. Further experiments were made on feeding behaviour, particularly of the young starfish. Samples required to give information on the growth and distribution of starfish were obtained from regular surveys of an oyster bed, by a series of parallel dredge hauls covering both cultivated and derelict bottoms. In November 1954, a section of oyster ground, 125 m wide, and stretching from one bank to the other (Fig. 1),was marked out at the Southward Laying, River Crouch. The first dredge haul was made with two 4 ft. 6in. dredges over the 125 m width, parallel to the edge of the north shore at L.W.a.S.T. and 10 m from it. Buoys were used to mark distances offshore, and subsequent dredge hauls were made parallel with each other 20 m apart, and, when time permitted, were continued as far as the south shore, giving a total of twenty-six stations. -
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). -
