Monitoring Discards in Mediterranean and Black Sea Fisheries: Methodology for Data Collection ISSN 2070-7010 FAO 639 FISHERIES AND AQUACULTURE TECHNICAL PAPER 639 Monitoring discards in Mediterranean and Black Sea fisheries: Methodology for data collection Monitoring discards in Mediterranean and Black Sea fisheries Methodology for data collection Discards – the part of the catch that is not retained on board, which may include target species or any other (commercial and non-commercial) species that are returned at sea dead or alive – usually result in a reduction of harvesting opportunities and may have negative consequences on the stocks, ecosystems and the marine environment. In the Mediterranean and the Black Sea, studies on discards only cover a small portion of the total fishing activities and discard rates are often poorly estimated or totally unknown. Information is lacking for many types of fishing gear, countries and GFCM subregions, and most available studies only cover relatively short periods and small areas. Discards therefore represent a major source of uncertainty about the actual fishing mortality rates of stocks. These knowledge gaps highlight the need to expand discard monitoring programmes and standardize practices, so to assess discards appropriately and address their important impacts. This publication and the methodology discussed herein aim to provide a framework for the development and implementation of an efficient, standardized data collection and monitoring system for discards through on-board observations, questionnaires at landing sites and self-sampling activities. It ensures minimum common standards for the collection of discards data and allows for repeatability and comparisons among fisheries across the region, thus offering a harmonized basis of knowledge, information and evidence for decision-making.

This includes the mid-term strategy (2017–2020) towards the sustainability of Mediterranean and Black Sea fisheries (mid-term strategy) and in particular its Target 4, “Minimize and mitigate unwanted interactions between fisheries and the marine ecosystems and environment”. This document contributes to the objective set in the mid-term strategy of reducing bycatch rates as a way to safeguard the profitability and sustainability of fisheries through a harmonized framework to increase knowledge on discards and support data collection in the GFCM area of application. It was produced ahead of the implementation of a GFCM discards monitoring programme in Albania, Algeria, Egypt, Lebanon, Montenegro, Morocco, Tunisia, Turkey and Ukraine between 2019 and 2020, whose results will provide a clear overview of the phenomenon and support the identification of appropriate management measures at both the subregional and regional levels. Paolo Carpentieri, GFCM Fishery Resources Monitoring Specialist, elaborated the methodology and was responsible for the general coordination and compilation of this document. He relied on important baseline information gathered by the GFCM throughout the development of its Data Collection Reference Framework (DCRF)1, during the implementation of scientific surveys-at-sea or in other contexts such as the European Union (EU) Data Collection Framework (DCF). The multiple-step collaborative approach adopted in his analyses allowed for the identification of flexible, relevant methods for Mediterranean and Black Sea fisheries. This work also builds upon the methodologies developed in similar concurrent data collection programmes, such as the programme on incidental catches of vulnerable species carried out by the GFCM in collaboration with a number of partner organizations operating in the Mediterranean. The document was submitted for review to the national focal points involved in the implementation of the GFCM discards monitoring programme, namely: Ahmed Inal (Algeria), Imad Lahoud (Lebanon), Ana Pešić (Montenegro), Sana El Arraf (Morocco), Nader Ben Hadjamida (Tunisia), Hüseyin Özbilgin (Turkey) and Serhii Snihirov (Ukraine), who gave their technical inputs on the methodology and helped improve the templates for data collection based on their field experience. The Regional Coordination Group for the Mediterranean and Black Sea (RCGMed&BS) of the European Commission (EC) also contributed additional information based on ongoing EU discards collection programmes. This led to the establishment of appropriate coordination mechanisms and to the alignment of data collection methodologies to compare results across the different countries and areas. Finally, the work was submitted to the GFCM Scientific Advisory Committee on Fisheries (SAC) and the GFCM Working Group on the Black Sea (WGBS) who endorsed it and provided feedback for its finalization. The editing, graphics, layout and publishing were coordinated by Dominique Bourdenet, GFCM Scientific Editor, with the assistance of Julia Pierraccini, GFCM Language and Communications Specialist, and Lauriane Palopoli, GFCM Editing/Communications Intern. Barbara Hall served as language editor, and Chorouk Benkabbour managed the graphic design and layout. This document was produced with the financial support of the EU.

Abstract The assessment of Penaeidae species diversity in a particular region is very important in formulating conservation strategies. In the present study, the survey on diversity of Penaeidae species in south east coast of India has been assessed on the basis of landing of variety of species in this group. Penaeidae species were collected from various main landing centers of south east coast of India for three years. Identification and nomenclature was done based on previously published literature. Among the 59 species observed, the Penaeus semisulcatus, Penaeus monodon and Fenneropenaeus indicus were found mostly in all landing centers.

E-mail: [email protected] 2 Renewable Resources Assessment Group (RRAG), Department of Environmental Science and Technology, Imperial College, Prince Consort Road, London, UK. 3 Marine Resources Assessment Group (MRAG), 27 Campden Street, London, UK. SUMMARY:Analytical stock assessment of sardine (Sardina pilchardus, Walb.) in the Adriatic Sea from 1975 to 1999 was performed taking into account the occurrence of discarding at sea of sardine caught by the Italian fleet. We have attempted to model the fishermen’s behaviour using data collected by an observer on board fishing vessels. This enabled us to estimate the amounts of discards, which were added to the catches landed, collected by ISMAR-CNR Ancona. Discards were calculated for the period 1987-1999, as their values were negligible before 1987. Stock assessment on the entire data series from 1975-1999 was carried out by means of Virtual Population Analysis (VPA). Discarding behaviour differs among ports due to different local customs and market conditions. The quantity added to the annual total catch ranged from 900 tonnes to 4000 tonnes, corre- sponding to between 2% and 15% of the total corrected catch.

  • Integrating Multiple Chemical Tracers to Elucidate the Diet and Habitat of Cookiecutter Sharks Aaron B
    www.nature.com/scientificreports OPEN Integrating multiple chemical tracers to elucidate the diet and habitat of Cookiecutter Sharks Aaron B. Carlisle1*, Elizabeth Andruszkiewicz Allan2,9, Sora L. Kim3, Lauren Meyer4,5, Jesse Port6, Stephen Scherrer7 & John O’Sullivan8 The Cookiecutter shark (Isistius brasiliensis) is an ectoparasitic, mesopelagic shark that is known for removing plugs of tissue from larger prey, including teleosts, chondrichthyans, cephalopods, and marine mammals. Although this species is widely distributed throughout the world’s tropical and subtropical oceanic waters, like many deep-water species, it remains very poorly understood due to its mesopelagic distribution. We used a suite of biochemical tracers, including stable isotope analysis (SIA), fatty acid analysis (FAA), and environmental DNA (eDNA), to investigate the trophic ecology of this species in the Central Pacifc around Hawaii. We found that large epipelagic prey constituted a relatively minor part of the overall diet. Surprisingly, small micronektonic and forage species (meso- and epipelagic) are the most important prey group for Cookiecutter sharks across the studied size range (17–43 cm total length), with larger mesopelagic species or species that exhibit diel vertical migration also being important prey. These results were consistent across all the tracer techniques employed. Our results indicate that Cookiecutter sharks play a unique role in pelagic food webs, feeding on prey ranging from the largest apex predators to small, low trophic level species, in particular those that overlap with the depth distribution of the sharks throughout the diel cycle. We also found evidence of a potential shift in diet and/or habitat with size and season.

Casey Ministry of Agriculture, Fisheries and Food Directorate of Fisheries Research Fisheries Laboratory Pakefield Road, Lowestoft, Suffolk NR33 OHT, U.K. Abstract A model is described to predict the numbers at age of fish discarded in fisheries for which only landings at age are known. The model assumes a knowledge of the E distributionoflengthwiftneachagegroupindiepoputhfion,andusesmeshselection 0 characteristics, and an inferred discarding practice, to derive the proportions of each 0 age group discarded and landed. Mesh selectivity and discarding practice, in terms of 0 proportions of the catch discarded and landed, are described using a logistic fit to the proportions of the population entering the net that are caught, discarded and landed. The application of the model is illustrated using data from the mixed demersal fisheries 11 .1 in the Irish Sea, and the effects of mesh size and effort changes on catch predictions are examined. 71-5 t9 Introduction Catches of finfish in the Irish Sea are dominated by four main species; the common sole (Solea solea (Linnaeus, 1758)), plaice (Pleuronectesplatessa Linnaeus, 1758), cod (Gadus morhua Linnaeus, 1758) and whiting (Merlangias merlangus (Linnaeus, 1758)). The demersal fishery for these species in the Irish Sea is prosecuted by 3 main fleets, each using a different gear type; beam trawlers, otter trawlers and Nephrops trawlers.
