   不久前，分享了一本简易手册——美国奥本大学渔业和水产联合部出版的《养殖池塘底质管理》，跟帖关注的人也比较多，都反映一个问题，这本手册居然英文版的，很多人只能望而却步，进来溜达一下看到是英文版的就走了。
   林文辉是珠江水产研究所的研究员，主要从事水产应用领域的研究（水化学、底质氧化还原电位等），翻译了奥本大学Boyd教授的池塘养殖水质、池塘养殖底质两本书，主要介绍水化学和底质的内容。而这本《养殖池塘低质管理》就是由奥本大学Boyd教授等人编写。林文辉翻译的《池塘养殖水质》《池塘养殖底质》这两本书稀缺，很多人都没见过其真容，网上更无这两本书的电子版。有人问我是否有这两本书，当然没有，故上网搜索Boyd教授的大作，《池塘养殖水质》《池塘养殖底质》这两本英文电子版的尚有，但不完整，有幸我找到了《养殖池塘底质管理》这本小手册与大家分享。可惜的是这本手册是英文版的，而我英文水平有限以及翻译要花大量时间，故不能翻译给大家，故今日想到一办法。我把手册上的内容一页一页贴上来，大家一起翻译，一起学习，如何？？？？
   下面全民学英语活动就正式开始拉？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

  接下来，就看大家了，赶紧动眼动脑动手，把它翻译过来或主要内容总结出来！！！！！！！！！！
