This book is a completely new edition of Fresh Seafood-The Commer cial Buyer's Guide, which was first published in 1984. There have been many changes in both product and the seafood business in the intervening years. About 70 percent of the material in this book is new, a tribute to the rapid pace of change throughout the industry. The subject of this book is fresh seafood. Fresh is defined as product handled under refrigeration (mechanical or ice) from har vester to consumer. This excludes frozen product, canned product and other shelf-stable packaging. Frozen seafoods are covered in the companion volume, The New Frozen Seafood Handbook. Many prod ucts are, of course, handled in both refrigerated and frozen forms. There may be substantial differences, not just in how they are han dled, but in how they are processed, graded and packed. Frozen sea foods are often treated and traded as commodities, with standard descriptions. Marketing and distributing fresh fish and shellfish, which has to be eaten within days of harvest, is necessarily more personal and direct. The contest between refrigerated and frozen seafoods has continued for many years and shows no signs of resolving. Despite massive im provements in the quality of much frozen product, consumers and their retail and restaurant suppliers still tend to believe that fresh is bet ter, perhaps simply because the word fresh is naturally appealing.
