Certification of European perch from the Irikla Reservoir (basin of the Ural River) according to the standards of the Marine Stewardship Council

Certification according to the standards of the Marine Stewardship Council (MSC) is highly demanded in the world market of seafood products. In Russia, a number of fisheries already have MSC certificates, but still there is a significant potential for certification of other fisheries. This requires analysis of the experience of companies that have successfully obtained the certification. Special attention should be paid to small-scale fisheries, whose financial opportunities to participate in certification programs, unlike large fisheries, are seriously limited. In the present work, process of ecological certification of fishery is considered on an example of the gillnet fishery of European perch Perca fluviatilis in the Irikla Reservoir, located in the middle course of the river Ural in the Orenburg Province. The catch volume of perch is 200–250 metric tons during the recent years. Fishing companies that fish in this reservoir have been working on MSC certification for over ten years. Process of certification has shown that the fishery meets the necessary standards, but even after the certification completed in 2016, there is a need for certain activities to support certification. These are in-depth analysis of the recreational fisheries, development of research plans in cooperation with scientific fishery institutes, specifically aimed at informing the certification process, independent analysis of the fisheries management system, detailed study of various bycatch species. It can be concluded that positive experience of this small-scale fishery with ecological certification can be important in improving fisheries management not only in Russia but also worldwide.

Seafood Certification and Non-governmental Organizations. In the last 20 years, many non-governmental organizations (NGOs) have become involved in providing advice on what seafood to eat, or in certifying different seafood products as well-managed or sustainable. The same NGOs have also become quite involved in the politics of fisheries management. The Marine Stewardship Council provides the most widely recognized certification of seafood sustainability and is increasingly demanded by major retailers in some countries. NGOs involved in marine conservation have become a roughly $500-million-per-year business, funded by foundations and private donors, and with a business model that compels them to raise concerns about fisheries sustainability to maintain cash flow.

Eustrongylides spp. is considered a freshwater fish zoonotic nematode. In the present study, the prevalence of Eustrongylides spp. in six edible fish (European perch - Perca fluviatilis, goldfish - Carassius auratus, largemouth black bass - Micropterus salmoides, tench- Tinca tinca, carp - Cyprinus carpio and sand smelt - Atherina boyeri) of Trasimeno lake was surveyed. The investigations were conducted from October 2014 to September 2015 and 384 specimens per species for each season were caught in Trasimeno lake and examined for the presence of larvae in the abdominal cavity and muscle. The presence of nematodes in the abdominal cavity and musculature was revealed in three fish species. The prevalence of Eustrongylides spp. infection was 6.84, 1.89 and 0.13% in perch, largemouth black bass and sand smelt, respectively. The number of parasites per fish was only one in largemouth black bass and sand smelt and ranged from one up to three in perch. This study states that the European perch, largemouth black bass and sand smelt of Trasimeno lake are infected with zoonotic parasites; therefore, food business operators have to take appropriate measures to guarantee the health of consumers.

Conservation Governance

AbstractOne of the most difficult situations for conservation is where state capacity to regulate is weak, major corporate organizations are absent, and the population does not have a strong culture of wildlife conservation. All these apply to the hugely popular urban Indonesian pastime of keeping wild songbirds, thought to be responsible for rolling local extinctions of several native species. In such situations the introduction of a voluntary, market-based approach could interact with regulation to create new and more effective approaches to reducing the negative conservation impacts of the associated trade. Here we assess the potential of such an approach through an in-depth analysis of the socio-economic and cultural aspects of bird keeping. We project that overall the pastime contributes USD 78.8 million to the economies of the six cities surveyed, supporting a range of associated small-scale rural and urban livelihoods relating to the production of cages and collection of live bird food. Finally, we describe five general bird-breeding models with the capacity to scale up the production of captive-bred birds that may substitute for wild-caught conspecifics. Based on this information we argue that a market-based policy instrument that is capable of shifting bird-keeping trends from wild-caught birds to captive-bred alternatives would align easily with macro-policy agendas in Indonesia relating to pro-poor growth and the creation of more and better jobs. Such a policy instrument could provide exciting opportunities for conservationists to engage the interest and support of non-conservation sectors in Indonesia in efforts to conserve diminishing populations of wild birds.

Efl Classrooms

Textbooks are one of the primary sources of input in EFL classrooms (Northbrook & Conklin, 2018). Textbooks cannot, however, suit the needs of every teacher or student who uses them (McGrath, 2002). As such, the principled evaluation of prospective textbooks becomes an important function in EFL contexts. In this small-scale study, three Japanese junior high school textbooks are evaluated to assess the extent to which they meet the requirements set by MEXT and the teachers who use them. Littlejohn’s (2011) textbook analysis framework is employed to conduct an in-depth analysis of the textbooks. The results reveal that the junior high school textbooks are surprisingly homogenous in nature, however, they are well suited to the context for which they are intended and broadly satisfy the requirements of policy makers and teachers. The ensuing discussion identifies a number of strengths and weaknesses that can broadly be applied to all three textbooks. 教科書はEFL教育現場において、インプットの最も主要なもののひとつである(Northbrook & Conklin, 2018)。しかしながら、教科書は使用者である教師や生徒のニーズをすべて満たしているわけではない (McGrath, 2002)。それ故に、使用される教科書を一定の観点で評価することは、EFL教育においてとても重要である。本論は、日本の中学校教科書が、文部科学省の設定する目標や使用者である教師のニーズにどの程度対応しているかを評価することを目的としている。Littlejohn (2011) による教科書分析の手法を用いて、異なる三社の教科書を詳細に分析した。結果として、当該の教科書は驚くほど同質でありながらも、中学校の英語教育の状況によく適合しており、また文部科学省と教師双方の要求に幅広く対応していることが明らかになった。さらに、先に分析した三つの教科書に共通する長所と短所についても論じる。

Time and spatial variations in macroparasite status were investigated in European perch, Perca fluviatilis, European whitefish, Coregonus lavaretus, and Arctic charr, Salvelinus alpinus in Lake Norsjø (Southern Norway), based on gillnet fishing in three locations in the spring, summer, and fall 2018. In addition, length, weigth, age, sex, δ13C, and δ15N were determined. Parasite abundance was modelled using negative binomial generalized linear models in relation to fish metrics, season, and sampling location. The most prevalent parasite species were determined by the diet and habitat of the host. European perch was mainly infected by acanthocephalans, European whitefish mainly infected by acanthocephalans and cestodes, and Arctic charr mainly infected by cestodes. The most prevalent parasites in European perch are transmitted by benthic animals. Parasites in European whitefish are transmitted by both benthic animals and copepods, while the most prevalent parasites in Arctic charr are copepod transmitted. This corresponds well with the δ13C signatures in the three species, indicating that European perch primarily fed in the littoral zone (δ13C: -24.9 ± 2.5 ‰), Arctic charr in the pelagic and profundal zone (δ13C: -29.4 ± 1.1 ‰), while European whitefish both fed in the littoral and pelagic zone (δ13C: -28.3 ± 2.3 ‰) of Lake Norsjø. Individual abundances of parasites depended on host age, length, sex, δ15N, and season. Positive correlations between parasite abundance and host age, length, or trophic level measured as δ15N were most common, and occurred in all three host species. Many parasites accumulate with age, and larger hosts provide more diverse habitats for parasites.

The Way

The Marine Stewardship Council eco-labelling scheme was formed in order to provide a means of promoting sustainable fisheries that moved away from conventional top-down management. In order to remain robust and transparent, MSC allows stakeholders to object to a certification through an objections process outlined by MSC. Over the past 15 years, this objections process has come under increasing scrutiny. The MSC OP has been accused of Ambiguous wording, principal agent issues and an unequal judicial process by some stakeholders and outside commentators. These accusations pose a real threat to the reputation of the MSC. If left un-addressed, MSC’s credibility amongst consumers and academics has the potential to be lost. This thesis seeks to investigate the legitimacy and robustness of the MSC OP. There is a focus on the way in which the MSC OP facilitates interactions between objection actors, influences actors, and how each actor is empowered by the MSC OP methodology.
