Fiskar

Sillens betydelse kan inte överskattas. Den fångades och åts av människor redan för tusentals år sedan. Havets silver har mättat magar och skapat förmögenheter bortom vår fattningsförmåga. Genom åren har den glänst och simmat, men aldrig fått något riktigt erkännande. Inte förrän nu, med den här boken! 

I ett unikt samarbete har historikern Tomas Andersson och biologen Stefan Edman skrivit den magnifika berättelsen om allt du vill veta om sillen, planetens vanligaste ryggradsdjur. Den sällskapliga fisken som mår dåligt och dör i förtid om den råkar hamna utanför stimmet med miljarder andra kamrater. Här finns nya rön om sillens sexliv, genetiken, rollen som nyckelart i havens ekologi. Och som mat åt oss människor, med en mängd av hälsosamma ämnen och molekyler som förhoppningsvis kan förebygga Alzheimers och Parkinsons sjukdom. 

Utan sillen skulle Östersjö- och Nordsjöländernas historia tett sig annorlunda, såväl politiskt som kulturhistoriskt. Boken följer Clupea harengus från stenåldern ända in i våra dagars diskussion om hur sill och strömming bör förvaltas på ett bättre och mer hållbart sätt i våra intensivt utnyttjade hav. 

Om författarna

Tomas Andersson är arkeolog, historiker och författare som i många år intresserat sig för Västerhavet och bland annat skrivit böckerna Bohusläns historia, I II. Sillen drabbade honom som en blixt från klar himmel. Det var ingen tvekan om vad nästa bok skulle handla om.

Stefan Edman är biolog, föreläsare och författare till ett 50-tal böcker om natur miljö samhälle, bl.a. Bohuskusten förr och nu, Planeten havet, Havsblänk och Makalös makrill. Hans morfar startade en av de första konservfabrikerna på Klädesholmen. Njuter av sill varje dag!

Flodnejonöga, nätting, har traditionellt fiskats i de norrländska älvarnas mynningsområden under uppströmsvandringen från havet till lekområdena, men fisket har minskat. Den fångas även längs den finska kusten och i Baltikum. Redskapen görs av vidjor, ribbor av trä, eller brädor, numera även av plast och metall. Här berättas om artens ekologi och tidigare nyttjande i mathushållningen. Idag är fisket begränsat, men av vissa anses den rökta nättingen vara en delikatess.

Kjell Sjöberg är född 1942 och uppväxt i Partille. Efter universitetsexamen i Uppsala och lärarhögskola i Umeå doktorerade han vid Umeå universitet i ämnet zoologi. Han är professor emeritus i viltekologi vid Sveriges lantbruksuniversitet (SLU) i Umeå. Hans forskning har främst berört andfågelekologi, men även insekter som födobas för fåglar. Flodnejonöga som en viktig födoresurs för fiskätande fåglar, främst skrakar, i de norrländska älvarnas mynningsområden ingick i hans studier som ligger till grund för denna bok. I boken medverkar även Kjell Danell, John P. Ball, Lars-Erik Edlund, Olof Sandström och Ingvar Svanberg.

The profound and life-affirming memoir about finding our way in a chaotic world.

'A sumptuous, surprising, dark delight' Carmen Maria Machado

'Her book took me to strange depths I never imagined, and I was smitten' NYT

As the daughter of a scientist, Lulu Miller was taught that chaos will come for us all. There is no cosmic destiny, no grand plan. But years later, reeling from heartbreak, she stumbles upon the story of David Starr Jordan - a fearless taxonomist devoted to order.

Looking to cure her crisis of confidence, Lulu is intrigued by the hubris of this mighty biologist, who refused to admit defeat when lightning struck his laboratory and earthquakes shattered his collection. Until, digging deeper, she makes a startling discovery. One that will upend her wish for a neatly catalogued existence and reveal the profound beauty of embracing chaos.

Remarkably little is known about the European eel, Anguilla anguilla. So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the "eel question" Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don't understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery. Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson crafts a mesmerizing portrait of an unusual, utterly misunderstood, and completely captivating animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel's point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea. Blending memoir and nature writing at its best, Svensson's journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death. The result is a gripping and slippery narrative that will surprise and enchant.

Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world.

The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate.

The Physiology of Tropical Fishes is the 21st volume of the well-known Fish Physiology series and consists of 12 chapters. The purpose of the book is to consolidate and integrate what is known about tropical fishes (marine and freshwater species). The twelve chapters focus on the physiological adaptations acquired during the evolutionary process to cope with warm and shallow hypoxic waters from tropical and neotropical hydrographic basins as well as with the intertidal and coral reef habitats which occur in abundance in tropical seas. The special characteristics of tropical fish fauna will be issued in order to explain the tropical fish radiation, which gave rise to such extreme fish diversity.

This present volume, is a voyage through the tropical region reviewing the fish diversity of the main tropical freshwater sheds, including the major tropical rivers and lakes, the major dams, and marine environments.

Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained.

The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry.
