Fish) of the Helford Estuary
HELFORD RIVER SURVEY A survey of the Pisces (Fish) of the Helford Estuary A Report to the Helford Voluntary Marine Conservation Area Group funded by the World Wide Fund for Nature U.K. and English Nature P A Gainey 1999 1 Summary The Helford Voluntary Marine Conservation Area (hereafter HVMCA) was designated in 1987 and since that time a series of surveys have been carried out to examine the flora and fauna present. In this study no less that eighty species of fish have been identified within the confines of the HVMCA. Many of the more common fish were found to be present in large numbers. Several species have been designated as nationally scarce whilst others are nationally rare and receive protection at varying levels. The estuary is obviously an important nursery for several species which are of economic importance. A full list of the fish species present and the protection some of them receive is given in the Appendices Nine species of fish have been recorded as new to the HVMCA.

Salcombe Bioblitz 2015 Final Report.Pdf
FINAL REPORT 1 | P a g e Salcombe Bioblitz 2015 – Final Report Salcombe Bioblitz 2015 This year’s Bioblitz was held in North Sands, Salcombe (Figure 1). Surveying took place from 11am on Sunday the 27th September until 2pm on Monday the 28th September 2015. Over the course of the 24+ hours of the event, 11 timetabled, public-participation activities took place, including scientific surveys and guided walks. More than 250 people attended, including 75 local school children, and over 150 volunteer experts and enthusiasts, families and members of the public. A total of 1109 species were recorded. Introduction A Bioblitz is a multidisciplinary survey of biodiversity in a set place at a set time. The main aim of the event is to make a snapshot of species present in an area and ultimately, to raise public awareness of biodiversity, science and conservation. The event was the seventh marine/coastal Bioblitz to be organised by the Marine Biological Association (MBA). This year the MBA led in partnership with South Devon Area of Outstanding Natural Beauty (AONB) and Ambios Ltd, with both organisations contributing vital funding and support for the project overall. Ambios Ltd were able to provide support via the LEMUR+ wildlife.technology.skills project and the Heritage Lottery Fund. Support also came via donations from multiple organisations. Xamax Clothing Ltd provided the iconic event t-shirts free of cost; Salcombe Harbour Hotel and Spa and Monty Hall’s Great Escapes donated gifts for use as competition prizes; The Winking Prawn Café and Higher Rew Caravan and Camping Park offered discounts to Bioblitz staff and volunteers for the duration of the event; Morrisons Kingsbridge donated a voucher that was put towards catering; Budget Car Hire provided use of a van to transport equipment to and from the event free of cost; and donations were received from kind individuals. -

Early Stages of Fishes in the Western North Atlantic Ocean Volume
ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation. -

Age, Growth and Population Dynamics of Lemon Sole Microstomus Kitt(Walbaum 1792)
Age, growth and population dynamics of lemon sole Microstomus kitt (Walbaum 1792) sampled off the west coast of Ireland By Joan F. Hannan Masters Thesis in Fish Biology Galway-Mayo Institute of Technology Supervisors of Research Dr. Pauline King and Dr. David McGrath Submitted to the Higher Education and Training Awards Council July 2002 Age, growth and population dynamics of lemon sole Microstomus kitt (Walbaum 1792) sampled off the west coast of Ireland Joan F. Hannan ABSTRACT The age, growth, maturity and population dynamics o f lemon sole (Microstomus kitt), captured off the west coast o f Ireland (ICES division Vllb), were determined for the period November 2000 to February 2002. The maximum age recorded was 14 years. Males o f the population were dominated by 4 year olds, while females were dominated by 5 year olds. Females dominated the sex ratio in the overall sample, each month sampled, at each age and from 22cm in total length onwards (when N > 20). Possible reasons for the dominance o f females in the sex ratio are discussed. Three models were used to obtain the parameters o f the von Bertalanfly growth equation. These were the Ford-Walford plot (Beverton and Holt 1957), the Gulland and Holt plot (1959) and the Rafail (1973) method. Results o f the fitted von Bertalanffy growth curves showed that female lemon sole o ff the west coast o f Ireland grew faster than males and attained a greater size. Male and female lemon sole mature from 2 years o f age onwards. There is evidence in the population o f a smaller asymptotic length (L«, = 34.47cm), faster growth rate (K = 0.1955) and younger age at first maturity, all o f which are indicative o f a decrease in population size, when present results are compared to data collected in the same area 22 years earlier. -

Control of Meiobenthic Abundance by Macroepifauna in a Subtidal Muddy Habitat
MARINE ECOLOGY PROGRESS SERIES Vol. 65: 241-249, 1990 Published August 16 Mar. Ecol. Prog. Ser. l Control of meiobenthic abundance by macroepifauna in a subtidal muddy habitat Emil 'Olafsson*,Colin G. Moore Department of Biological Sciences. Heriot-Watt University, Riccarton, Edinburgh EH14 4AS. Scotland ABSTRACT: In order to assess the effects of macrofauna on meiofaunal community structure, field investigations were performed in a low energy subtidal muddy sediment in Loch Creran, a sea-loch on the west coast of Scotland. Meiofaunal colonization of azoic sediment in cages designed to exclude macrofauna to varylng degrees was studied. After 1 mo nematode density in all 15 cages was less than a third of ambient density. In none of the cages did the nematodes reach ambient densities within the experimental period. Copepods attained background levels in 3 mo in all cages and were in higher numbers in cages designed to exclude all macrofauna. Results indicate that small to medium sized macroepifauna control the densities of copepods at the study site. INTRODUCTION Apart from experiments conducted by Dauer et al. (1982) at a very shallow (1.5 m) sandy site, every preda- Although meiofauna used to be regarded as a trophic tor exclusion experiment dealing with meiofauna has dead end (McIntyre & Murison 1973), it is now acknow- been performed intertidally and often on sandy sub- ledged as an important food resource for higher trophic strata.

Bataillon, cc63, 34095 Montpellier Cedex 5, France. Summary: The existence of cryptic salinity-related phenotypes has been hypothesized in the “euryhaline” sea bass (Dicen- trarchus labrax). How differential osmoregulation costs between freshwater and saltwater environments affect fitness and phenotypic variation is misunderstood in this species. During an experiment lasting around five months, we investigated changes in the whole body mass and in the expression of growth-related genes (insulin-like growth factor 1 [IGF-1]; growth hormone receptor [GHR]) in the intestine and the liver of sea bass thriving in sea water (SSW), successfully acclimated to freshwater (SFW), and unsuccessfully acclimated to freshwater (UFW). Albeit non-significant, a trend toward change in body mass was demonstrated among SSW, UFW and SFW fish, suggesting that SSW fish were a mixture of the other phe- notypes. Several mortality peaks were observed during the experiment, with batches of UFW fish showing higher expression in the osmoregulatory intestine due to down-regulation of genes in the liver and significant up-regulation of GHR in the intestine compared with SFW fish. -
First Record of the Reticulated Dragonet, Callionymus Reticulatus

First record of the reticulated dragonet, Callionymus reticulatus Valenciennes, 1837 (Actinopterygii: Callionymiformes: Callionymidae), from the Balearic Islands, western Mediterranean. Acta Ichthyol. Piscat. 47 (2): 163–171. Background. The reticulated dragonet, Callionymus reticulatus, was originally described based on a single specimen, the holotype from Malaga, Spain, south-western Mediterranean, probably collected before 1831. The holotype is now disintegrated; the specific characteristics are no longer discernible. The species was subsequently recorded from several north-eastern Atlantic localities (Western Sahara to central Norway), but missing in the Mediterranean. Material and methods. Specimens of C. reticulatus were observed and collected during two cruises in 2014 and 2016 in the Balearic Islands off Mallorca and Menorca. The collected specimens (8 females) have been deposited in the collection of the Hebrew University of Jerusalem (HUJ). All individuals of C. reticulatus were collected from beam trawl samples carried out during the DRAGONSAL0914 in September 2014, and during the MEDITS_ES05_16 bottom trawl survey in June 2016, on shelf and slope bottoms around the Balearic Islands. Both surveys used a ‘Jennings’ beam trawl to sample the epi-benthic communities, which was the main objective of the DRAGONSAL0914 and a complementary objective in the MEDITS_ES05_16. The ‘Jennings’ beam trawl has a 2 m horizontal opening, 0.5 m vertical opening and a 5 mm diamond mesh in the codend. -

Box 101, Victoria Road, Aberdeen AB9 8DB, Scotland FICHE NO. 1501151 SOL E I DA E OF THE EASTERN NORTH ATLANTIC J. H. Nichols Fisheries Laboratory Lowestoft, Suffolk NR 33 OHT, England (This sheet may be referred to in the following form: Nichols, J. H. 1976. Soleidae, Fich. Ident. Zooplancton 150/151: .10 pp.) https://doi.org/10.17895/ices.pub.5120 Conseil International pour 1’Exploration de la Mer Charlottenlund Slot, DK-2920 Charlottenlund Danemark SEPTEMBRE 1976 2 INTRODUCTION This sheet deals in detail with the four species of Soleidae occurring commonly within the areas listed in Table 1. The Soleidae are a warm- water family, reaching the northerly limit of their distribution in the northern North Sea. Consequently, many more genera are found south of the Atlantic area covered by Table 1, and in the Mediterranean. The adult of one of the southerly genera Dicologlossu uzeviu, has been recorded once in the western English Channel and it also occurs occasionally in the southern part of the Bay of Biscay. Insufficient information on the egg and larval development of this genus, and the rare deep-water form Buthysoleu profondicolu, is available for them to be included here. This sheet should be used together with no. 4-6, (NICHOLS,1971), on the Pleuronectidae, which includes a key to the families in the order Hetero- somata. The information on material and methods in that sheet is also applicable here. Since its publication I have found the use of a polarized light system on a steroscopic microsccpe extremely useful for counting vertebrae and myotomes when these are necessary.
