Existe una pequeña criatura que habita en los océanos y que desde siempre ha despertado el interés de los seres humanos: se trata del caballito de mar, un pez sin escamas que nada erguido y que, en lugar de boca, posee una trompa para alimentarse. Estas caracteristicas, junto con el hecho de que sean los machos los que paren, son solo algunas de las peculiaridades de estos fascinantes animales que desvelara este libro. Los caballitos de mar se han convertido en un objeto muy preciado para los amantes de los acuarios y su indiscriminado comercio ha generado un negocio muy lucrativo en todo el mundo; en la actualidad es una especie amenazada, por lo que esta obra tambien explica cuales son las tecnicas de cria en cautividad que se estan desarrollando ante la degradacion de sus habitats y cuales son las medidas que se deben llevar a cabo para que podamos contribuir a la conservacion de sus poblaciones naturales

Seguramente nos imaginamos que los peces tienen una vida sencilla y efímera, que solo se dedican a ocupar un lugar en la cadena alimenticia, a procrear y nadar, sin mayores objetivos. Pero la realidad es mucho mas estimulante y compleja, asegura Jonathan Balcombe, etologo y autor de este extraordinario libro que revela las asombrosas capacidades de unos seres sensibles, conscientes, sociales e incluso astutos y engañosos, muy parecidos a nosotros. A traves de un viaje por mares, rios y deltas, asi como por las aguas dulces o saladas de los acuarios, descubriremos como se comportan y que piensan y sienten los peces, criaturas de una diversidad y belleza abrumadoras. Aunque las mas de treinta mil especies marinas superan a las de los mamiferos, aves, reptiles y anfibios juntos, rara vez nos preguntamos por los medios que emplean los peces para identificar los lugares que habitan, desde marismas de aguas poco profundas hasta oceanos insondables, o sobre los vinculos que establecen con sus compañeros de banco y los modos como planifican, cooperan, se congracian o se decepcionan. Basandose en los ultimos datos cientificos y su propia experiencia, Balcombe reflexiona sobre nuestra relacion con los animales acuaticos y nos invita a adoptar una actitud mucho mas amable con ellos y su entorno, cada vez mas amenazado. Y es que El ingenio de los peces cambiara nuestra manera de contemplar a estos seres inteligentes, cuyas vidas tienen un valor intrinseco, ajeno al caracter utilitario que solemos asignarles.

En una madrugada serena pero cargada de energia, Lynne nadaba en aguas frias, a doscientos metros de la costa, cuando se percato de que algo nadaba por debajo de ella. Aquello parecia lo bastante grande como para ser un tiburon blanco, pero no lo fue. Resulto ser un bebe ballena que habia perdido a su mama en el mar, y que habia seguido a Lynne por mas de una milla. Si Lynne no lograba encontrar a la mama, el bebe ballena se deshidrataria y moriria de hambre. Algo tan enorme como la mama ballena, que media quince metros, de pronto parecia muy pequeña en el vasto oceano Pacifico. ¿Como podria encontrarla Lynne?

The story of herring is entwined in the history of commercial fishing. For over two millennia, herring has been commercially caught and its importance to the coastal peoples of Britain cannot be measured. At one point tens of thousands were involved in the catching, processing and sale of herring. They followed the shoals around the coast from Stornoway to Penzance and many towns on Britains east coast grew rich on the backs of the silver darlings.Fishing historian Mike Smylie looks at the effects of herring on the people who caught them, their unique ways of life, the superstitions of the fisher folk, their boats and the communities who lived for the silver darlings.With a wealth of illustrations, this fascinating book reveals the little-known history of the herring. And for those whove neglected the silver darlings for lesser fish such as cod and haddock, there are a number of mouth-watering recipes to try.
