    Jubilee Field Draft EIA Chapter 4 6 Aug 09.Pdf

    4 ENVIRONMENTAL AND SOCIO-ECONOMIC BASELINE 4.1 INTRODUCTION This chapter provides a description of the current environmental and socio- economic situation against which the potential impacts of the Jubilee Field Phase 1 development can be assessed and future changes monitored. The chapter presents an overview of the aspects of the environment relating to the surrounding area in which the Jubilee Field Phase 1 development will take place and which may be directly or indirectly affected by the proposed project. This includes the Jubilee Unit Area, the Ghana marine environment at a wider scale and the six districts of the Western Region bordering the marine environment. The Jubilee Unit Area and its regional setting are shown in Figure 4.1. The project area is approximately 132 km west-southwest of the city of Takoradi, 60 km from the nearest shoreline of Ghana, and 75 km from the nearest shoreline of Côte d’Ivoire. Figure 4.1 Project Location and Regional Setting ENVIRONMENTAL RESOURCES MANAGEMENT TULLOW GHANA LIMITED 4-1 The baseline description draws on a number of primary and secondary data sources. Primary data sources include recent hydrographic studies undertaken as part of the exploration well drilling programme in the Jubilee field area, as well as an Environmental Baseline Survey (EBS) which was commissioned by Tullow and undertaken by TDI Brooks (2008). An electronic copy of the EBS is attached to this EIS. It is noted that information on the offshore distribution and ecology of marine mammals, turtles and offshore pelagic fish is more limited due to limited historic research in offshore areas.

    Some Biological Aspects of Brown Comber, Serranus Hepatus (L.) (Pisces: Serranidae), in the Sea of Marmara, Turkey

    Some biological aspects of brown comber, Serranus hepatus (L.) (Pisces: Serranidae), in the Sea of Marmara, Turkey Zeliha ERDOĞAN, Hatice TORCU-KOÇ* Department of Biology, Faculty of Science and Arts, University of Balikesir, Cağış Campus, 10145, Balikesir, Turkey. *Corresponding author: [email protected] Abstract: Age, growth, gonadosomatic index and condition factor of brown comber, Serranus hepatus (L.) were evaluated from 162 specimens collected in Bandırma Bay, the Sea of Marmara between the years of 2012 and 2013 by the hauls of trawls. Total length ranged between 6.5-11.1 cm, while weight varied between 3.62 and 21.52 g. The length-weight relationship was W=0.0216*L2.84, showing negative allometry. According to otolith readings, samples were determined between 1–5 years. The von Bertalanffy growth -1 parameters were estimated as L∞=12.46 cm, k=0.19 year , to=–4.32, W∞=34.77 g, k=0.09 -1 year and to=-1.63. Although brown comber has no economic value for Turkish Seas, it is important in the view of biodiversity. Keywords: Serranus hepatus, Sea of Marmara, Growth, Sex-ratio.

Gabriel Roca 69, 07157 Port d’Andratx, Islas Baleares, Spain ABSTRACT: We examined the short-term movements of a small temperate fish, the painted comber Serranus scriba (Linnaeus 1758), within the marine protected area (MPA) of Palma Bay (NW Mediter- ranean) using passive acoustic telemetry. Fifteen adults were surgically implanted with acoustic transmitters and monitored between July 2007 and February 2008 for periods of up to 36 d. Inter- individual variability was detected for both spatial and temporal patterns. There were 2 principal movement behaviours that were recorded, with some individuals showing high site fidelity and others showing a more mobile behaviour, moving out from the monitoring area. Observation-area curves indicated that a period between 3 and 5 d was required to determine home ranges of the sedentary fish. Home range sizes were small, with a minimum shift of core areas occurring on a daily basis. Total minimum convex polygon (MCP) areas ranged between 0.102 and 0.671 km2, whereas 95% kernel utilization distributions (KUD) ranged between 0.760 and 1.333 km2. Core areas (50% KUD) ranged between 0.175 and 0.294 km2.

However, technological constraints (e.g., battery life and limited storage memory) typically limit deployment times to <2 h making it very difficult to capture the presence of marine species, including rare and elusive ones. We developed an extended duration (24 h) BRUV to enable fisheries-independent surveying of a pelagic shark population in the western Mediterranean. Video data revealed seven visits (three nocturnal, four diurnal) by blue sharks (Prionace glauca) over a period of 1355 h. In the future, this cost-effective device could be fitted with a wireless video transmitter to provide real-time observations of marine animals for scientific or ecotourism purposes.

A total of 2410 specimens were analyzed, and of those, 2290 individuals were mature and 120 individuals were juvenile. Analyses covered all individuals because the species is a simultaneous hermaphrodite. The length–weight relationship was determined as W = 0.013L3.11, indicating a positive allometric growth for all samples. The estimated −1 von Bertalanffy growth parameters were L∞ = 13.19 cm, k = 0.252 y , and to = −0.630 y, and the infinite weight (W∞) was calculated as 39.38 g. The growth performance index (φʹ) of the stock was calculated as 1.642. The first reproduction length was found to be 7.76 cm, corresponding to 3 years of age. The spawning period of the species was determined between May and October. Key words: Brown comber, Serranus hepatus, age, growth, reproduction, first reproduction length, central Aegean Sea 1. Introduction Regarding reproduction strategies, gonadal Serranus hepatus (Linnaeus, 1758), known as brown differentiation can be observed in many teleost fish comber, is a member of the family Serranidae.

A preliminary study on the survival of brown comber, Serranus hepatus (Actinopterygii, Perciformes, Serranidae), escaping from the codend of a bottom trawl. Acta Ichthyol. Piscat. 40 (1): 27 –36. Background. Poor selectivity of trawl cod-ends has been a major problem of the modern-day fisheries, contribut - ing to destruction of non-target organisms. It is expected that increased trawl selectivity can reduce bycatch and discards. This would only be true if significant numbers of the escaping fishes survive. The chances of survival of many species after escaping the trawl cod-end are still poorly known. This study was aimed at providing mor - tality estimates of brown comber, Serranus hepatus , escaping from two different demersal trawl cod-ends (40 mm diamond and square) in the Aegean Sea. We also looked at possible seasonal variation in the survival rate of escaped brown comber (diamond mesh). Materials and Methods. Two experiments were conducted off the Yassıca Island, İzmir Bay (Aegean Sea, Turkish coast): in winter 2007 and summer 2008. Five hauls were performed in winter (January–February 2007), and nine hauls in late summer (September 2008).

A total of 1568 specimens were collected from January 2016 to April 2018. Total length (TL) varied between 9.3 and 26.2 cm. The maximum total length recorded in the Mediterranean Sea for the species is 26.2 cm (TLmax). The von Bertalanffy growth parameters were estimated using ELEFAN I routine in FiSAT II program -1 -1 (L∞ = 32.80 cm; K = 0.41 yr ; t0 = - 0.39 yr ) and those related to the length-weight relationship are as follows: 2 -1 W∞ = 372.15 g; a = 0.012 and b = 2.96 (r = 0.93). Total mortality (Z) and natural mortality (M) coefficients stood at 2.63 yr and 0.43 yr-1, respectively. The calculated exploitation rate, E = 0.84, indicated that S. cabrilla population is overexploited. Keywords: Bony fish, Comber, Population dynamics, Serranids,Serranus cabrilla Introduction are needed for fitting population dynamics models and for demographic analyses (Khan and Khan, 2014). The comber Serranus cabrilla (Linnaeus, 1758), is a teleost fish of commercial interest, common in the The current study provides the first information on Mediterranean, Western Black Sea and Atlantic Ocean, some biological parameters of S.
