不久前，分享了一本簡易手冊——美國奧本大學漁業和水產聯合部出版的
《養殖池塘底質管理》 ，跟帖關注的人也比較多，都反映一個問題，這本手冊居然英文版的，很多人只能望而卻步，進來溜達一下看到是英文版的就走了。
林文輝是珠江水產研究所的研究員，主要從事水產應用領域的研究（水化學、底質氧化還原電位等），翻譯了奧本大學Boyd教授的池塘養殖水質、池塘養殖底質兩本書，主要介紹水化學和底質的內容。而這本《養殖池塘低質管理》就是由奧本大學Boyd教授等人編寫。林文輝翻譯的《池塘養殖水質》《池塘養殖底質》這兩本書稀缺，很多人都沒見過其真容，網上更無這兩本書的電子版。有人問我是否有這兩本書，當然沒有，故上網搜索Boyd教授的大作，《池塘養殖水質》《池塘養殖底質》這兩本英文電子版的尚有，但不完整，有幸我找到了《養殖池塘底質管理》這本小手冊與大家分享。可惜的是這本手冊是英文版的，而我英文水平有限以及翻譯要花大量時間，故不能翻譯給大家，故今日想到一辦法。我把手冊上的內容一頁一頁貼上來，大家一起翻譯，一起學習，如何？？？？
下面全民學英語活動就正式開始拉？Are you ready?

INTRODUCTION
Water quality management has been considered one of themost important aspects of pond aquaculture for many years,but less attention has been given to the management of pondbottom soil quality. There is increasing evidence that thecondition of pond bottoms and the exchange of substances between soil and water strongly influence water quality(Boyd, 1995). More attention is being devoted to the study of pond soils, and practical aquaculturists are beginning to seek information on pond bottom management.
The purpose of this small manual is to provide a practicalguide to the management of aquaculture pond soils.
POND SOILS
Development
During pond construction, surface soil in the area to become the pond bottom usually is scraped off and used as earth fill for embankments. The newly finished pond bottom normally is subsoil low in concentrations of organic matter and nutrients. In tropical and subtropical areas with highly leached soils, pond bottoms often are high in clay content and of low pH.After filling with water, various processes begin to transform the bottom of a new pond into a pond soil. Erosion of the watershed results in suspended particles of mineral soil and organic matter entering a pond in runoff. Wave action, rainfall, and water currents from mechanical aeration erode embankments and shallow edges to suspend soil particles. In addition,nutrients added to ponds in fertilizers, manures, and feeds cause phytoplankton blooms that increase the concentration of suspended organic particles. Suspended particles settle in ponds with large sand particles settling first, followed by
接下來，就看大家了，趕緊動眼動腦動手，把它翻譯過來或主要內容總結出來！！！！！！！！！！
