Also, I am grateful to the FAO regional project EastMed and to the Institute for Coastal Marine Environment of the CNR (IAMC-CNR) for their vital technical support and to the ENVIMED Mistral CNRS France for its financial support for the LESSEPS project. All these institutions are made up of human beings that encouraged, suggested, brainstormed, discussed or simply lent me a hand before, during and after the implementation of the field activities. I wish to acknowledge a debt of gratitude to Biagio Di Terlizzi, Samir Majdalani and Francesco Colloca for their continuous guidance, their help and the friendship they honor me with. My gratitude also goes to Myriam Lteif, Sharif Jemaa and all the colleagues of the NCMS of Batroun and to Dahej el Mokdad, Imad Lahoud and the rangers of the MoA assigned to the DFW-MoA. This study could not have been completed without the support of the Lebanese fishermen, their bravery and tough job in the sea. In particular, I wish to acknowledge the fishermen Toufic Assal from Batroun and Nicholas Rahmé from Tyre for their vital technical advice. Lastly, I wish to acknowledge the privilege to have worked with extremely knowledgeable supervisors. I offer them my deep gratitude, to my supervisor Professor Gaby Khalaf and my co- supervisor Dr. Marion Verdoit-Jarraya.

ABSTRACT Knowledge on the precise identification of fish resources is critical for sustainable fisheries management. This study employs the DNA barcoding approach to generate a molecular taxonomic catalogue of commercially important reef fishes in the waters of Weh Island (Aceh Province), the most northerly inhabited island in the biodiverse Indonesian Archipelago. The waters not only support artisanal fisheries but also a feeder for the industry in the greater island of Aceh. In total, 230 specimens from 72 species belonging to 32 genera and 17 families were DNA barcoded, representing a major segment of the captured reef fish taxa and a quarter of fish species diversity that had previously been recorded. The sequence read lengths were 639 bp revealing 359 conserved sites, 280 variable sites, 269 parsimony informative and 11 singletons. Our molecular findings paralleled the morphological identification with no evidence of cryptic species or new species discovery. This study is a significant contribution to the fisheries statistics of this area, which would facilitate assessment of species catch composition and hence for strategizing management plans. It is an important input to Submitted 6 August 2019 the DNA barcode library of Indonesian marine fishes and to the global DNA barcode Accepted 9 July 2020 entries in general.

  • Some Aspects of the Taxonomy, Biology, Possible Evolution and Biogeography of Nematodes of the Spirurine Genus Rhabdochona Raill
    DOI: 10.2478/s11686-010-0017-3 © W. Stefan´ski Institute of Parasitology, PAS Acta Parasitologica, 2010, 55(2), 144–160; ISSN 1230-2821 Some aspects of the taxonomy, biology, possible evolution and biogeography of nematodes of the spirurine genus Rhabdochona Railliet, 1916 (Rhabdochonidae, Thelazioidea) František Moravec* Institute of Parasitology, Biology Centre of the Academy of Sciences of the Czech Republic, Branišovská 31, 370 05 České Budějovice, Czech Republic Abstract At present the nematode genus Rhabdochona Railliet, 1916 (Rhabdochonidae) comprises 92 possibly valid species, mostly in- testinal parasites of freshwater fishes in all zoogeographical regions. Because of the absence of any phylogenetic studies using molecular methods in this nematode group, an attempt to evaluate affinities among these parasites and their zoogeography on the basis of morphological features and host-parasite relationships has been carried out. Only true definitive hosts should be considered for such evaluation. It appears that, during the evolution of Rhabdochona spp., there occur an increase in the num- ber of anterior prostomal teeth, loss of lateral alae, the right spicule attains a boat-like shape and a dorsal barb develops on its distal tip, and the distal tip of the left spicule attains gradually a more complex structure; the eggs with a smooth surface are considered to be more primitive. Nematodes of this genus most probably originated in the region of present southern Asia at the beginning of Tertiary. Closest to the initial type appear to be members of the subgenus Globochona Moravec, 1972, from which lineages leading to the subgenera Globochonoides Moravec, 1975, Rhabdochona Railliet, 1916 and Sinonema Moravec, 1975 can be derived.

The designations employed and the presentation of material in this publication do not imply the expression of any opinion on the part of FAO or donors concerning the legal status of any country, territory, city or area, or concerning the determination of its frontiers or boundaries. ii Preface The Project “Scientific and Institutional Cooperation to Support Responsible Fisheries in the Eastern Mediterranean- EastMed is executed by the Food and Agriculture Organization of the United Nations (FAO) and funded by Greece, Italy and EC. The Eastern Mediterranean countries have for long lacked a cooperation framework as created for other areas of the Mediterranean, namely the FAO sub-regional projects AdriaMed, MedSudMed, CopeMed II and ArtFiMed. This fact leaded for some countries to be sidelined, where international and regional cooperation for fishery research and management is concerned.

Piscat. 50 (3): 325–332. Background. The population of Lagocephalus spadiceus (Richardson, 1845), one of the Lessepsian species that migrated from the Red Sea to the Mediterranean Sea through the Suez Canal, has been growing rapidly in Turkey in recent years. This situation poses a serious danger to fisheries and human health. There is little information about the biology of this species. The presently reported study permits a greater understanding of the age and growth characteristics of the pufferfish L. spadiceus from the Gulf of Iskenderun, north-eastern Mediterranean. Materials and methods. Samples were captured by commercial bottom trawlers at depths of 24–50 m during 9 trawling operations conducted during the fishing seasons between 2012 and 2013 in the Gulf of Iskenderun, north- eastern Mediterranean. Age determinations were carried out using vertebrae. Images of vertebrae suitable for age determination were obtained with a dissecting microscope. The index of the mean percentage error (IMPE) was calculated to assess the precision of the age determinations between two independent readers.

The user has requested enhancement of the downloaded file. Chapter 26 - Agnatha CHAPTER 26: AGNATHA, CHONDRICHTHYES AND OSTEICHTHYES FISHES Antonis Petrou and Charitos Zapitis 1. INTRODUCTION The classification of fishes is not straightforward since they do not form a natural scientific grouping like the other vertebrate classes, i.e. the amphibians, reptiles, birds and mammals. Indeed, fishes can be considered by exclusion to be vertebrates that are not tetrapods (see Chapter 25: Introduction to Vertebrates). They are aquatic, gill- bearing, ectothermic ('cold-blooded') animals with a distinguishable head and, when present, digit-less limbs. Traditionally, fish have been arranged into three groups: ➵ Agnatha 1, the jawless fish (Myxini [hagfishes] and Hyperoartia [lampreys]); ➵ Chondrichthyes, the cartilaginous fish (sharks, skates and rays); ➵ Osteichthyes, the bony fish (Actinopterygii [ray-finned fishes] and Sarcopterygii [lobe-finned fishes]). This classification is adequate for general purposes, although Agnatha is paraphyletic and includes several groups of extinct jawless fishes.
