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. -
First Record of the Reticulated Dragonet, Callionymus Reticulatus
ACTA ICHTHYOLOGICA ET PISCATORIA (2017) 47 (2): 163–171 DOI: 10.3750/AIEP/02098 FIRST RECORD OF THE RETICULATED DRAGONET, CALLIONYMUS RETICULATUS VALENCIENNES, 1837 (ACTINOPTERYGII: CALLIONYMIFORMES: CALLIONYMIDAE), FROM THE BALEARIC ISLANDS, WESTERN MEDITERRANEAN Ronald FRICKE1* and Francesc ORDINES2 1Lauda-Königshofen, Germany 2Instituto Español de Oceanografía, Centre Oceanogràfic de les Balears, Palma de Mallorca, Spain Fricke R., Ordines F. 2017. 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. -
Florida's Fintastic Sharks and Rays Lesson and Activity Packet
Florida's Fintastic Sharks and Rays An at-home lesson for grades 3-5 Produced by: This educational workbook was produced through the support of the Indian River Lagoon National Estuary Program. 1 What are sharks and rays? Believe it or not, they’re a type of fish! When you think “fish,” you probably picture a trout or tuna, but fishes come in all shapes and sizes. All fishes share the following key characteristics that classify them into this group: Fishes have the simplest of vertebrate hearts with only two chambers- one atrium and one ventricle. The spine in a fish runs down the middle of its back just like ours, making fish vertebrates. All fishes have skeletons, but not all fish skeletons are made out of bones. Some fishes have skeletons made out of cartilage, just like your nose and ears. Fishes are cold-blooded. Cold-blooded animals use their environment to warm up or cool down. Fins help fish swim. Fins come in pairs, like pectoral and pelvic fins or are singular, like caudal or anal fins. Later in this packet, we will look at the different types of fins that fishes have and some of the unique ways they are used. 2 Placoid Ctenoid Ganoid Cycloid Hard protective scales cover the skin of many fish species. Scales can act as “fingerprints” to help identify some fish species. There are several different scale types found in bony fishes, including cycloid (round), ganoid (rectangular or diamond), and ctenoid (scalloped). Cartilaginous fishes have dermal denticles (Placoid) that resemble tiny teeth on their skin. -

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. -
Appendix 13.2 Marine Ecology and Biodiversity Baseline Conditions
THE LONDON RESORT PRELIMINARY ENVIRONMENTAL INFORMATION REPORT Appendix 13.2 Marine Ecology and Biodiversity Baseline Conditions WATER QUALITY 13.2.1. The principal water quality data sources that have been used to inform this study are: • Environment Agency (EA) WFD classification status and reporting (e.g. EA 2015); and • EA long-term water quality monitoring data for the tidal Thames. Environment Agency WFD Classification Status 13.2.2. The tidal River Thames is divided into three transitional water bodies as part of the Thames River Basin Management Plan (EA 2015) (Thames Upper [ID GB530603911403], Thames Middle [ID GB53060391140] and Thames Lower [ID GB530603911401]. Each of these waterbodies are classified as heavily modified waterbodies (HMWBs). The most recent EA assessment carried out in 2016, confirms that all three of these water bodies are classified as being at Moderate ecological potential (EA 2018). 13.2.3. The Thames Estuary at the London Resort Project Site is located within the Thames Middle Transitional water body, which is a heavily modified water body on account of the following designated uses (Cycle 2 2015-2021): • Coastal protection; • Flood protection; and • Navigation. 13.2.4. The downstream extent of the Thames Middle transitional water body is located approximately 12 km downstream of the Kent Project Site and 8 km downstream of the Essex Project Site near Lower Hope Point. Downstream of this location is the Thames Lower water body which extends to the outer Thames Estuary. 13.2.5. A summary of the current Thames Middle water body WFD status is presented in Table A13.2.1, together with those supporting elements that do not currently meet at least Good status and their associated objectives. -
