Leeches, Lice and Lampreys: A Natural History of Skin and Gill Parasites of Fishes

Many alternative types of animals have followed a parasitic lifestyle at the pores and skin and gills of marine and freshwater fishes, together with protozoans, flatworms, leeches, a variety of crustaceans or even a few vertebrates (lampreys). there's a parasitic barnacle, defined first within the nineteenth century via Charles Darwin, fish lice that modify intercourse and bivalve molluscs parasitic in simple terms while younger.

The Underwater Museum: The Submerged Sculptures of Jason deCaires Taylor

A exceptional mixture of artwork, nature, and conservation, The Underwater Museum re-creates an awe-inspiring dive into the outstanding under-ocean sculpture parks of artist Jason deCaires Taylor. Taylor casts his life-size statues from a distinct type of cement that allows reef development, and sinks them to the sea ground.

Billion-Dollar Fish: The Untold Story of Alaska Pollock

Alaska pollock is all over. If you’re consuming fish yet you don’t be aware of what sort it really is, it’s in all probability pollock. Prized for its typical fish style, pollock masquerades as crab meat in california rolls and seafood salads, and it feeds thousands as fish sticks at school cafeterias and Filet-O-Fish sandwiches at McDonald’s.

Example text

Catches have been kept stable in Greenland so far with a fixed quota based on landings during previous years, but no research has been carried out since the 1980s that could lead to improvements in management. Norway is a diVerent case because the oVshore stocks were wiped out so quickly that hardly any data had been collected before the fishery collapsed, but the conservative approach could have been tried in Bjørnøya, where scallop dredging has taken place occasionally over the past 15 years.

The required fisheries data are age composition of the catch, annual CPUE and fishing eVort. This information is fed into a model to estimate the removal and weight at age of scallops for any given fishing mortality. The goal is to optimise yield per recruit. The model can be used to regulate the fishery by regulating the age and size of capture (gear selectivity) and control fishing eVort by regulating fishing mortality under the assumption of self-recruiting populations. Basically, this consists of fishing only the older scallops so each year-class has the chance to spawn over several years.

Ramos and J. P. Jo´nasson read the manuscript, and V. Chosson helped me to produce the maps. Thanks are also due to the editor, Alan Southward, and three anonymous referees; their comments were very useful for improving the manuscript. REFERENCES Anonymous (1973). Rannso´knir a´ ho¨rpudiski.
