Nine people were arrested, including three Russians and a Pole, during clashes outside San Mames in which a police officer died of a heart attack.The incident also raised fears over hooliganism at this summer’s World Cup which will be hosted by Russia.“Football was invented to be enjoyed, for people to experience happiness or suffer with their teams,” said Barcelona coach Valverde, formerly in charge in Bilbao.“But others use football as an excuse for other things, because football is seen by so many. It sullies football but it is not a problem for football, it is a wider problem. And of course we absolutely condemn that.”FIFA said it “deeply regrets” the clashes in Bilbao but had “complete trust” in Russia’s ability to ensure a safe World Cup — despite this being just the latest incident of hooligan violence involving Russians.A minute’s silence will be held before all games in Spain’s top two divisions this weekend in memory of the dead policeman.“La Liga reiterates its strongest condemnation of the violence and continues to work to eradicate it from football,” La Liga said in a statement.Spanish Prime Minister Mariano Rajoy earlier offered his condolences for the death of the 51-year-old Basque police officer as he also “strongly condemned” the violence in the northern Spanish city.The officer was one of over 500 deployed to San Mames for the high-risk Europa League last-32 tie.He “suddenly felt ill during the serious incidents… despite being taken quickly to hospital, he suffered cardiac arrest,” the Basque government’s security department said in a statement, adding his death was not “directly” linked to an injury he suffered in the clashes.The trouble began as Spartak ‘ultras’ arrived at the stadium.Some lit and threw smoke bombs and bins towards Athletic supporters, before police charged them.Police detained five Spaniards, three Russians and a Polish man over the clashes, a spokesperson for the Basque security department said. They face charges of causing public disorder, rioting and disrespect for authority.Five other police officers were injured, none of them seriously, and treated on the scene, the spokesperson added.There was concern ahead of the match because of the reported presence of hardcore Russian fans in Bilbao, and police seized knives, bags full of rocks and brass knuckles from supporters of the two teams, the Basque security department said.Earlier Thursday, German police arrested a Russian suspected of the “attempted murder” of a British football fan during the European Championship in France two years ago. He was detained at Munich airport as he was trying to travel to Bilbao to attend the match, according to German police.But a spokesman for Russia’s embassy in Germany, Denis Mikerine, “strongly protested” the arrest on Facebook, saying it was a “possible pretext” to “politicise the theme of football hooliganism before the 2018 World Cup in Russia”.Russian authorities will be on high alert this summer for the World Cup after Russian fans were involved in pitched battles with England supporters in Marseille during Euro 2016.Spartak won Thursday’s match 2-1, but Athletic went through 4-3 on aggregate.They will face Marseille in the next round in March, but Spanish rivals Atletico Madrid have been drawn against another Russian club in Lokomotiv Moscow.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Police made nine arrests during violence before Thursday’s Europa League match between Athletic Bilbao and Spartak Moscow in which a Spanish police officer died of a heart attack © AFP / ANDER GILLENEAMadrid, Spain, Feb 23 – Real Madrid coach Zinedine Zidane and his Barcelona counterpart Ernesto Valverde on Friday strongly condemned the violence which led to a police officer dying before a Europa League game in Spain between Athletic Bilbao and Spartak Moscow.“Our thoughts are with his family. I don’t like violence, and it is very hard to understand when these things happen. Let’s hope these things don’t happen again in a football stadium,” said Zidane of the incidents which took place prior to Thursday evening’s match.
Experimental study on the effect of diet on fatty acid and stable isotope profiles of the squid Lolliguncula brevis
Fatty acid and stable isotope analyses have previously been used to investigate foraging patterns of fish, birds, marine mammals and most recently cephalopod species. To evaluate the application of these methods for dietary studies in squid, it is important to understand the degree to which fatty acid and stable isotope signatures of prey species are reflected in the squids’ tissue. Four groups of Lolliguncula brevis were fed on prey species with distinctly different fatty acid and stable isotope profiles over 30 consecutive days. One group of squid were fed fish for fifteen days, followed by crustaceans for a further fifteen days. A second and third group were fed exclusively on fish or crustaceans for thirty days. And a fourth group was fed on a mixture of fish and crustaceans for thirty days. Analysis of squid tissue showed that, after 10 days of feeding, fatty acid profiles of squid tended to reflect those of their prey. Squid that fed on a single prey type, i.e. fish or crustacean, showed only minor modifications in fatty acid proportions after the initial change and fatty acid profiles were clearly distinguishable between the two feeding groups. Shifts in fatty acid proportions towards respective prey profiles could clearly be observed in squid the diet of which was swapped after 15 days. Clear differences could also be seen in fatty acid profiles of squid feeding on a mixed diet with trends towards either fish or crustacean fatty acid signatures. Stable isotope signatures of squid tissues clearly distinguished between animals feeding on different diets and supported findings from fatty acid analysis, thus indicating both methods to be viable tools in feeding studies on squid species.
