fish van in csp.

the van parks up on the corner by richard adams the chemist...i spent 3 years when a student in a fish processing plant filleting fish and stuff for the supermarkets and stores, fresh fish should not smell ' bad' in any way, if you buy fish do not leave it in a plastic bag in the fridge... greaseproof paper is better, it needs to ' breathe' any smell like ammonia and its off........smoked fish sometimes smells a bit... as alot of the yellow colouring is dye and these chemicals have odours and taint the fish, just ensure if you buy whole wet fish that the eyes are bright and clear... any cloudyness like a cataract then walk away, the gills should be a good blood red colour, not a pasty washed out pink.... filleted fish should have good shiny supple skin, if it creases as the fillet is handled then it has been round a while..... cod if it is really fresh may have small tiny ' lice' on the skin side, abouit the size of a grain of rice, and light brown in colour, these only attatch themselves to good fresh fish, if the fish in the fish shop display has them then its very fresh..... you get similar lice on salmon, the ones that go for salmon are the size and colour of a lentil !- if the fish is not fresh these harmless lice fall off,  so if they are present its a good sign.... honest !
