Разработка технологии соленой продукции из медузы Rhizostoma pulmo (Macri, 1778)
No full textIncrease in the barrel jellyfish abundance, recently observed in the Azov and Black Sea Fishery Basin, has an adverse effect on the fishery and tourism in the region. Jellyfish consumption is a longstanding tradition for the countries of East and Southeast Asia, where the processing technology for jellyfish is based on the salting involving potassium alum. Jellyfish treatment with potassium alum leads to the accumulation of aluminum in the final product, which poses a threat for the human health. Thus, the research of the jellyfish processing methods excluding the use of aluminum is of utmost importance. This study was aimed at the development of the salting methods for barrel jellyfish Rhizostoma pulmo that would involve using plant-based tanning substances. This article presents processing scheme and technological parameters for the salted products derived from jellyfish. Using tanning substances extracted from oak bark and green tea leaves in the quantity of no less than 0.75 % of the jellyfish brought for salting (in terms of weight) made it possible to obtain the salted product with condensed structure. For a lightly salted product, salting should be conducted in 8–10 % saline solution at the temperature 4±2 °С. Based on the identified technological parameters and the assessment of quality and safety characteristics of the obtained samples of salted jellyfish, specifications and processing instruction for the salted products derived from jellyfish for its further use as a food ingredient in multicomponent recipes have been developed.Рост численности медуз, который наблюдается в последнее время в Азово-Черноморском рыбохозяйственном бассейне, отрицательно влияет на рыболовство и туристическую деятельность региона. Потребление медуз традиционно для стран Восточной и Юго-Восточной Азии, где технологии обработки медуз основаны на посоле с использованием алюмокалиевых квасцов. Обработка медуз алюмокалиевыми квасцами приводит к накоплению алюминия в готовой продукции и представляет серьезную проблему для здоровья человека. В связи с этим исследования, исключающие использование алюминия при переработке медуз, являются актуальными. Целью исследования являлась разработка альтернативного способа посола медуз Rhizostoma pulmo с использованием дубильных веществ, извлеченных из растительного сырья. В статье представлена технологическая схема и приведены технологические параметры изготовления соленой продукции из медуз. Использование дубильных веществ коры дуба и листьев зеленого чая в количестве не менее 0,75 % от массы медузы, направляемой на посол, позволило получить соленую продукцию с уплотненной текстурой. Для получения малосоленой продукции предлагается осуществлять посол в 8–10%-ном солевом растворе при температуре 4±2 °С. На основании установленных технологических параметров и оценки показателей качества и безопасности полученных образцов соленой медузы разработаны технические условия и технологическая инструкция по изготовлению соленой продукции из медуз для дальнейшего ее использования в качестве пищевого ингредиента при приготовлении поликомпонентных блюд.PublishedReferee
Oceano sem mistérios : Construindo cidades azuis
No full textCidade Azul é aquela que promove a sustentabilidade - social, ambiental, econômica, cultural e em sua governança - integrando políticas públicas e ações de cidadãos e instituições com o oceano. Portanto, ser uma cidade azul é fortalecer a relação da sustentabilidade com o oceano! E não importa a distância do mar, mesmo cidades do interior podem, e devem, ser azuis. A cultura oceânica é definida como o “entendimento da influência do oceano em nossas vidas e de nossas ações no oceano”, no qual “nós” corresponde a indivíduos e instituições, sejam elas públicas ou privadas. Ela é feita com todos os diferentes setores da sociedade, considerando suas especificidades locais e de forma integrada e colaborativa. É importante pontuar que este documento não traz uma fórmula única ou guia para uma Cidade Azul, pois cada cidade possui sua realidade social, cultural, ambiental, econômica e de infraestrutura política e administrativa. Este documento também não busca iniciar ou trazer novas demandas, mas sim inserir uma lente azul nas iniciativas, projetos e ações já realizadas ou em andamento, valorizando e ampliando o impacto destas ações. Aqui, você vai encontrar estratégias divididas em sete esferas principais - educação, economia azul sustentável, turismo, adaptação, água e saneamento, saúde e bem- estar e conservação - que podem ser adotadas de forma conjunta ou individualmente. Todas elas dialogam e ajudam seu município a alcançar os Objetivos de Desenvolvimento Sustentável da Agenda 2030, além de responder aos Desafios da Década da Ciência Oceânica para o Desenvolvimento Sustentável (2021 - 2030). Tomadores de decisão, servidores públicos dos municípios e Estados, este é um convite e oportunidade para discutir, adaptar e aplicar os caminhos aqui apresentados e, assim, construir sua cidade azul.PublishedReferee
Working Group on Fisheries Benthic Impact and Trade-offs (WGFBIT).
No full textThe Working Group on Fisheries Benthic Impact and Trade-offs (WGFBIT) develops methods and performs assessments to evaluate benthic impact from fisheries at regional scale, while con- sidering fisheries and seabed impact trade-offs. In this report, new fishery benthic impact assessments (ToR A) are shown out for several sub- regions in (French Mediterranean, Celtic Seas). For other regions, updates of the whole assess- ment or specific steps only were presented. To further standardise the different components of the WGFBIT approach across all (sub-)re- gional assessments, a more detail overview of those components was compiled. These compo- nents were slightly different among those regions, related to variation in data availability, envi- ronmental characteristics and implementation possibilities among the (sub-)regions. In WGFBIT, assessments are sometimes based on trawl or grab data, which are sampling differ- ent components of the seafloor ecosystem and can have consequences on the created sensitivity layer. Therefore, there is looked in more detail how the sensitivity outcome (and layers) can dif- fer due to the use of benthic data gathered with different gears (grab/core, trawl or video). The preliminary comparability analyses are performed on different levels: (1) based on co-located sampling; (2) comparing sensitivity maps of the (sub-) area, based on different gears. There were differences observed in longevity distribution at locations sampled with different gears and dif- ferences in data and models lead also to differences in the sensitivity layers. The WGFBIT seafloor assessment framework is not the only way to assess benthic impacts from physical disturbance. A discussion session was held on how the future workflow on advice that ICES WGFBIT assessment contribute to, will be organized. Marine sediments harbour significant levels of biodiversity that play a key role in ecosystem functions and services such as biogeochemical cycling, carbon storage and the regulation of cli- mate. Through the removal of fauna, changes in physico-chemical nature and resuspension of sediment, bottom trawling may result in significant changes in the ecosystem functioning of shelf seas. An assumption of the current PD model is that high community biomass implies higher ecosystem functioning. However, total community biomass does not necessarily reflect changes in species and functional trait composition which play a key role in regulating ecosystem func- tions. ToR D is working on an improved understanding of the link between species functional effect traits and proxies and processes for specific ecosystem functions to improve our ability to predict the impact of fishing disturbance on benthic ecosystem functioning more accurately. Links between species traits and biogeochemical parameters and the impact of trawling on these links are being explored using multivariate ordination analyses using different fauna and bioge- ochemical datasets collected in the North Sea, Celtic Sea, Kattegat, Baltic Sea and the eastern Mediterranean. Changes due to trawling in the trajectories of species densities over time and the concurrent changes in the bioturbation and bioirrigation potential of communities are being modelled using a combination of data-driven mechanistic model and a biogeochemical model. We report on the different data analysis methods that ToR D members have developed over the last year.ICESPublishedReferee

Экспериментальная оценка токсикорезистентности бентосной микроводоросли Thalassiosira excentrica Cleve 1903 (Bacillariophyta) при воздействии ионов меди
No full textWith an increase in anthropogenic pressure on the ecosystem of the coastal zones of the sea, the relevance of assessing the state of plankton and benthos communities also increases. In the course of the study, the dynamics of the number of cells of the clone culture Thalassiosira excentrica Cleve 1903 (Bacillariophyta) has been determined under the influence of CuSO4·5H2O of various concentrations (32–1024 µg·L–1) under the conditions of 10-day experiments. In the control and at a low concentration of Cu2+, the proportion of living cells remains almost unchanged. The threshold concentration of copper ions for the survival of T. excentrica is 128 µg·L–1. At higher concentrations of Cu2+ (256–1024 µg·L–1), a sharp inhibition and death of the culture has been noted already within 1–3 days. The increase in the absolute number of cells at low concentrations of copper (32–64 µg·L–1) is described by the sigmoid response curve of the test-object. The growth values increase by 4–8 times on the 1st–5th day and decrease by 25–30 % by the 10th day. At Cu2+ concentrations of 128–256 µg·L–1, there is no positive increase in the number of cells on days 1–5; on subsequent days, it decreases by 2 times or drops to zero. The intensity of the specific cell growth significantly decreases depending on the increase in the concentration of the toxicant. It has been found that on days 1–5, the specific increase is positive in the range of copper concentrations of 32–128 µg·L–1 and negative – at concentrations of 256 µg·L–1 and higher. In the period of 5–10 days, for all concentrations of the toxicant, the values of the specific increase are negative. The obtained results make it possible to recommend T. excentrica as a promising test object for toxicological experiments.При усилении антропогенной нагрузки на экосистему прибрежных зон моря возрастает актуальность оценки состояния сообществ планктона и бентоса. В ходе исследования определена динамика численности клеток клоновой культуры Thalassiosira excentrica Cleve 1903 (Bacillariophyta) при воздействии CuSO4·5H2O разной концентрации (32–1 024 мкг·л –1) в условиях 10-суточных экспериментов. В контроле и при низкой концентрации Cu2+ доля живых клеток практически не изменяется. Пороговая концентрация ионов меди для выживания T. excentrica равна 128 мкг·л –1. При более высоких концентрациях Cu2+ (256–1 024 мкг·л –1) отмечено резкое угнетение и гибель культуры уже в течение 1–3-х суток. Прирост абсолютной численности клеток при низких концентрациях меди (32–64 мкг·л –1) описывается сигмоидной кривой отклика тест-объекта. Значения прироста возрастают в 1–5-е сутки в 4–8 раз и снижаются к 10-м суткам на 25–30 %. При концентрациях Cu2+ 128–256 мкг·л –1 положительный прирост численности клеток в 1–5-е сутки отсутствует, в последующие дни снижается в 2 раза либо падает до нуля. Интенсивность удельного прироста клеток достоверно снижается в зависимости от увеличения концентрации токсиканта. Установлено, что в 1–5-е сутки удельный прирост положительный в диапазоне концентраций меди 32–128 мкг·л –1 и отрицательный – при концентрациях 256 мкг·л –1 и выше. В период 5–10-х суток для всех концентраций токсиканта значения удельного прироста отрицательные. Полученные результаты позволяют рекомендовать T. excentrica в качестве перспективного тест-объекта для токсикологических экспериментов.PublishedReferee
