Chemical additives in weathered microplastic in the marine environment: occurrence and risk
Available online: https://pub.norden.org/temanord2022-520/ A Nordic project identified and measured residues of chemical additives in polyurethane (PUR) and polyvinyl chloride (PVC). Measurements were done in new plastic, and in plastic weathered for four months in Samnangerfjorden near Bergen. Targeted chemical analysis with GC-Orbitrap was performed for identification and GC-MS analysis for quantification. Four plasticizers were detected in PUR and three in PVC, before and after weathering: Dibutyl adipate, N-butylbenzenesulphonamide (only in PUR), dibutyl phthalate, and di-2-ethylhexyl phthalate (DEHP). Maximum concentrations were approx. 1000 ng/g plastic. Also triphenyl phosphite and octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate were identified. Risk quotients for copepods, cod and fulmar showed low risk. Additionally, non-target screening with GC-Orbitrap identified sixteen chemicals, of which two had hazard classifications.
Mycotoxins in Feed and Food Chain
The book deals with mycotoxins, their presence in various types of food, and how to prevent their presence in food . In addition to well-known molecules, such as aflatoxins or fumonisins, some contributors have dealt with emerging mycotoxins (e.g., alternaria toxins, botryodiplodin). Readers of the book can also find a new approach to reducing aflatoxins and fumonisins in food. In conclusion, the book presents both new mycotoxins and new information on old mycotoxins.
Nutrient Requirements of Fish and Shrimp
Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.
Book of Abstracts of the 67th Annual Meeting of the European Federation of Animal Science
This Book of Abstracts is the main publication of the 67th Annual Meeting of the European Association for Animal Production (EAAP). It contains abstracts of the invited papers and contributed presentations of the sessions of EAAP's nine Commissions: Animal Genetics, Animal Nutrition, Animal Management and Health, Animal Physiology, Cattle Production, Sheep and Goat Production, Pig Production, Horse Production and Livestock Farming Systems.

Fish Welfare
Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.
Utflyttarboka 2007 for Hareid og Ulstein
Med Personboka 2000 utvikla vi eit nytt konsept for bygdebøker. Ein kan kalle ho ein «kjapp-versjon». Kvar person er representert med ei linje. Namna står alfabetisk og boka er og register til eksisterande bygdebøker. Personboka vart utvikla og gitt ut i samråd med bygdeboknemndene i kommunene Hareid og Ulstein. Boka vart utgitt i 2001. Utflyttarboka 2007 tek med dei som har flytta frå øya og familien deira. Familien står gruppevis under namnet på utflyttaren. Boka er såleis ikkje ei oppdatering av Personboka 2000. Boka vart utgitt i 2007.
