Work in fishery institute (Ishikawa)

 


The other day, I went to do part time job in fishery institute of tsuruoka with some laboratory members. I really enjoyed it because I had not been involved with fishery industry but I was interested in it. Work was making mark on juvenile flatfishes will be released to sea. We made mark on flatfishes by cutting dorsal fins using chisels. While flat fishes can be marked with chisel, other fishes are marked with scissors, brand and so on. Flatfishes are usually have blackish color but I sometimes saw individuals have less color. Those individuals will be eaten by predators easily after being released to sea because they can not hide. I had opportunities I talked about sea creatures in English as I joined activity with international students. At that time, we talked about how we call “namako” in English. I knew “namako” was “sea cucumber” in English after searching. It is interesting！ Ayu, the fish known well in Japan, are called ayu in English also because they are rarely seen in area other than east asia. We can call them sweetfish in English too.

 

先日、研究室のメンバーと鶴岡市にある魚類の養殖場でバイトをしてきました。水産業には興味があったものの、一度も携わったことがなかったのでとても楽しかったです。海に放流する予定のヒラメの稚魚にマーキングをする仕事をしてきました。今回はヒラメの背びれを彫刻刀でカットしてマーキングをしました。ヒラメのように平らな魚は彫刻刀が使えますが、普通の魚ではハサミを使ったり焼き印を使ったりと色々なやり方があるみたいです。ヒラメは通常黒っぽい色をしていますが時々色があまりついていない個体が見られました。そのような個体は、海に放流しても擬態できずにすぐ捕食者に食べられてしまうそうです。今回は留学生と一緒だったので海の生き物について英語で話す機会がありました。その時になまこって英語でなんて言うんだろうと話になり、調べてみたのですが英語ではsea cucumber(海のきゅうり)と言うことが分かりました。面白いですね！他にも日本では良く知られている鮎ですが、東アジア以外の地域ではあまり見られないため英語でもayuと話されているそうです。一応sweetfishとも呼ばれることもあるようですが。

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

イメージ
I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

イメージ
We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
