Over the past three years, there has been a proliferation of applications of stock identification methods to ICES stocks, as well as several notable advances in stock identification methods with many results relevant to ICES science and advice. SIMWG provided annual updates on recent applications and advances in stock identification methods. Over the past three years, SIMWG received requests for guidance on stock structure of (1) European sardine (Sardina pilchardus), (2) Beaked redfish (Sebastes mentella) stock affiliation on the East Greenland slope, (3) Atlantic cod in ICES area 6a, and (4) red gurnard (Aspitrigla cuculus) stock structure in ICES subareas 3-8. These requests came from a range of ICES working groups including North Western Working Group (NWWG), the Workshop on Atlantic Sardine (WKSAR) and the Working Group on Widely Distributed Stocks (WGWIDE). SIMWG did not find sufficient evidence to support the recent change in stock structure of European sardine adopted in the 2017 benchmark and recom- mended review of new genetics research prior to the next benchmark. SIMWG did not recom- mend a combined assessment of beaked redfish along the east Greenland slope with the Icelandic slope. SIMWG reviewed and provided feedback on a proposed cod genetics study in ICES area 6a which promises to resolve some critical questions of stock identity of cod in ICES area 6a. SIMWG did not find strong evidence for splitting the red gurnard stock into two stock areas (North Sea/west of Scotland and Celtic Seas/Biscay). Over the past three years, SIMWG also made progress on reviewing and reporting on advances in mixed stock analysis. This work will continue through our next three year to and is relevant to resolving mixed stock composition issues in assessment and management. Understanding stock structure is a fundamental require- ment before any assessment or modelling on a stock can be contemplated and SIMWG will con- tinue to work with ICES expert groups to address pressing stock identification issues.

SIMWG has committed to providing annual updates on recent applications of stock identification methods to ICES species and on advances in stock identification methods. The group has focused on summarizing research in the focal areas listed below: • Genetics • Growth marks in calcified structures • Life history parameters • Morphometrics/meristics • Tagging • Otolith shape • Otolith chemistry • Parasites • Simulation approaches • Interdisciplinary approaches • Published Theme Sets SIMWG’s annual reviews on advances in stock identification methods keeps ICES members abreast of best practices in this field of study. This review activity has served as a valuable con- tribution to the field and has formed the foundational material for 2 editions of the book Stock Identification Methods: Applications in Fishery Science. This book was published first in 2005 and again in 2014. SIMWG members S. Cadrin, L. Kerr and S. Mariani edited the 2nd edition and several SIMWG members contributed chapters to this book. The details of annuals reviews of advances in stock identification methods are summarized in Annex 4. 2 | ICES SCIENTIFIC REPORTS 2:7 | ICES 2 Technical reviews and expert opinion on matters of stock identification SIMWG provides ICES expert groups and working groups expert feedback on questions of stock structure for ICES stocks. Over the past three years, SIMWG has contributed to ICES advisory needs by providing expert feedback on the status of stock structure of several species. These requests came from the North Western Working Group (NWWG), the Workshop on Atlantic Sardine (WKSAR), Working Group on Widely Distributed Stocks (WGWIDE), and in previous years we have connected with many more ICES groups to fulfill such requests. Over the past three years SIMWG provided expert recommendations on the following species: 1. European sardine (Sardina pilchardus); 2. Beaked redfish (Sebastes mentella) stock affiliation on the East Greenland slope; 3. Atlantic cod in ICES area 6a; 4. Red gurnard (Aspitrigla cuculus) stock structure in ICES subareas 3-8. The details of the reviews are summarized in Annex 4. SIMWG expert reviews on questions of stock structure for ICES stocks are directly relevant to the appropriate definition of stock and contribute to the accuracy of stock assessment and effec- tiveness of management actions. Understanding stock structure is a fundamental requirement before any assessment

They are viewed as a suitable alternative to industrial fisheries, particularly when considering their social and economic importance in developing countries. Here, we show that the booming small-scale fishery sector in Senegal, in the context of increasing foreign demand, has induced the collapse of one of the most emblematic West African marine fish species, a large grouper Epinephelus aeneus , historically called ‘false cod’ by European fishers. The overexploitation of this species appears to be on account of the increasing effort sustained by a growing international demand and important subsidies, which resulted in a relative stability of the average economic yield per fishing trip and an incentive for continuing targeting this species to almost extinction.

Omogoriola Nigerian Institute for Oceanography and Marine Research, No 3 Wilmot Point Road, Bar-beach Bus-stop, Victoria Island, Lagos, Nigeria. EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment).

Following global changes, Croatia is experiencing increasing problems due to the introduction of new species that include aliens (due to aquaculture activities and ship- ping) and species from other Mediterranean subregions that are extending their geographic range. This work provides a checklist of introduced species in Croatian waters. A total of 113 species (15 phytoplankton, 16 zooplankton, 16 macroalgae, 44 zoobenthic and 22 fish species) have been recorded in the eastern part of the Adriatic Sea, of which 61 species are alien and 52 introduced, due to climate change. Keywords: Alien species, range expansion, Croatia, Adriatic Sea, Mediterranean Sea. Introduction Considering all major characteristics, three biogeo- graphic regions can be recognized in the Adriatic Sea: a The Adriatic Sea is an elongated semi-enclosed basin shallow northern sub-basin and a deep southern sub-ba- in the Northeastern Mediterranean Sea.

Fish were obtained from Uzungöl. Enzymatic antioxidant activities (superoxide dismutase, catalase, glutathione peroxidase), glutathione and lipid peroxidation (malondialdehyde) were determined in spermatozoa of three trout species. Results indicated that catalase (23.36±0.36 K/g.protein), glutathione peroxidase (74.00±1.5 U/g.protein), glutathione (0.57±1.24 µmol/g.cell) and malondialdehyde levels (6.55±2.01 nmol/g cell) were highest levels in Anatolian trout (S.
