蟲(chóng)子的悲哀

      不久前，分享了一本簡(jiǎn)易手冊(cè)——美國(guó)奧本大學(xué)漁業(yè)和水產(chǎn)聯(lián)合部出版的《養(yǎng)殖池塘底質(zhì)管理》   ，跟帖關(guān)注的人也比較多，都反映一個(gè)問(wèn)題，這本手冊(cè)居然英文版的，很多人只能望而卻步，進(jìn)來(lái)溜達(dá)一下看到是英文版的就走了。
      林文輝是珠江水產(chǎn)研究所的研究員，主要從事水產(chǎn)應(yīng)用領(lǐng)域的研究（水化學(xué)、底質(zhì)氧化還原電位等），翻譯了奧本大學(xué)Boyd教授的池塘養(yǎng)殖水質(zhì)、池塘養(yǎng)殖底質(zhì)兩本書(shū)，主要介紹水化學(xué)和底質(zhì)的內(nèi)容。而這本《養(yǎng)殖池塘低質(zhì)管理》就是由奧本大學(xué)Boyd教授等人編寫(xiě)。林文輝翻譯的《池塘養(yǎng)殖水質(zhì)》《池塘養(yǎng)殖底質(zhì)》這兩本書(shū)稀缺，很多人都沒(méi)見(jiàn)過(guò)其真容，網(wǎng)上更無(wú)這兩本書(shū)的電子版。有人問(wèn)我是否有這兩本書(shū)，當(dāng)然沒(méi)有，故上網(wǎng)搜索Boyd教授的大作，《池塘養(yǎng)殖水質(zhì)》《池塘養(yǎng)殖底質(zhì)》這兩本英文電子版的尚有，但不完整，有幸我找到了《養(yǎng)殖池塘底質(zhì)管理》這本小手冊(cè)與大家分享�？上У氖沁@本手冊(cè)是英文版的，而我英文水平有限以及翻譯要花大量時(shí)間，故不能翻譯給大家，故今日想到一辦法。我把手冊(cè)上的內(nèi)容一頁(yè)一頁(yè)貼上來(lái)，大家一起翻譯，一起學(xué)習(xí)，如何？？？？
       下面全民學(xué)英語(yǔ)活動(dòng)就正式開(kāi)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

        等了這么久，也沒(méi)人來(lái)參加翻譯，{:soso_e150:}。
       我就來(lái)翻譯一下吧，不知準(zhǔn)不準(zhǔn)確。大家覺(jué)得哪里翻譯有錯(cuò)的，盡量提出來(lái)哈！！

                                                                                        前言
       多年來(lái)，水質(zhì)管理一直被認(rèn)為是池塘養(yǎng)殖 中最重要的環(huán)節(jié)，然而對(duì)池塘底質(zhì)管理問(wèn)題關(guān)注甚少。越來(lái)越多的證據(jù)顯示，池塘底部狀況以及底泥與水體界面之間的物質(zhì)交換對(duì)養(yǎng)殖水體有著很大的影響（Boyd,1995）.人們對(duì)池塘底泥越來(lái)越關(guān)注，養(yǎng)殖專家們也開(kāi)始從池塘底質(zhì)管理中尋找更多有利信息。
       這本小手冊(cè)可為大家提供養(yǎng)殖池塘底質(zhì)管理的實(shí)際指導(dǎo)。
                                                                                        塘泥
塘泥的形成：
       在建造池塘?xí)r，土地表層土壤被挖去用作塘堤土方。新建的池塘底部通常缺乏有機(jī)物和營(yíng)養(yǎng)成分。在熱帶及亞熱帶淋溶土分布地區(qū)，池塘底部常常含有豐富的粘土而且底部泥土PH也較低。
       新塘灌水后，各種反應(yīng)作用下使新塘底部形成塘泥。水流的侵蝕使礦質(zhì)土中的懸浮顆粒和有機(jī)物質(zhì)溶入池塘水體。波浪作用、降雨以及機(jī)械曝氣產(chǎn)生的水流不斷侵蝕塘堤和淺水邊緣使土壤微粒懸浮在水體中。隨后，通過(guò)施肥、投料增加水體營(yíng)養(yǎng)成分使浮游植物開(kāi)始生長(zhǎng)，水體中有機(jī)懸浮顆粒含量因此逐漸增多。剛開(kāi)始時(shí)，有機(jī)懸浮顆粒伴隨大沙粒進(jìn)入池塘，隨后，成為粉砂級(jí)顆粒，最后變?yōu)檎惩令w粒進(jìn)而完全被降解為小分子有機(jī)顆粒。

第二頁(yè)：

silt-sized particles, and finally clay particles and fine-divided organic matter. The names and sizes of soil particle classes are provided in Table 1. Water currents and activity of fish and other organisms continually resuspend particles from the bottom, and these particles settle again. Boyd (1976, 1977) reported that continuous input, deposition, resuspension, and redeposition of particles in a pond result in a sorting of particles with the fine clay and organic matter particles settling in the deeper water and the coarser particles settling in shallower water (Figure 1). Deeper areas gradually fill in, and ponds may decrease in volume. Sediment thickness in deep areas of aquaculture ponds usually increases at 0.5 to 1 cm yr-1(Munsiri et al., 1995; Tepe and Boyd, unpublished data).
         Organic matter settles to the bottom and is decomposed by microorganisms. Easily decomposable organic matter, such as simple carbohydrates, protein, and other cellular constituents, is quickly degraded. More resistant material, such as complex
carbohydrates and other cell wall components, accumulates because it is degraded slowly. There is a continuous input of organic matter to the bottom, so microorganisms are continuallydecomposing both fresh, easily degradable (labile)

第二頁(yè)翻譯：
根據(jù)沙粒大小可把沙粒分為不同種類，詳情見(jiàn)表1.

水流運(yùn)動(dòng)以及池塘中魚(yú)和其他動(dòng)物的運(yùn)動(dòng)不斷使池底粘土再次懸浮，然后有沉淀。Boyd (1976, 1977)研究表明，水體中懸浮顆粒的連續(xù)不斷的輸入、沉積，再懸浮，再沉積使得粘土和有機(jī)顆粒沉入更深的底部，而較大的沙粒往往沉淀到淺水區(qū)（見(jiàn)圖1）。深水區(qū)池底逐漸被淤泥覆蓋，池塘容積縮小。池塘中沉積物以每年0.5~1cm的厚度增加（Munsiri 等1995; Tepe和Boyd, 未發(fā)表數(shù)據(jù)）。

  有機(jī)物沉淀到池底被微生物分解。易分解的有機(jī)物，如簡(jiǎn)單的碳水化合物、蛋白質(zhì)和其他細(xì)胞成分很快被分解。那些耐腐蝕性的物質(zhì)，如復(fù)雜碳水化合物和其他細(xì)胞壁成分由于分解緩慢而沉積。由于不斷有新的有機(jī)物進(jìn)入池塘底部，因此微生物不僅要不停地分解新的、易分解的有機(jī)物，而且還要分解以前舊的耐降解的有機(jī)物。

第三頁(yè)（這頁(yè)大家來(lái)翻譯）：
          Because there is a more or less continuous resuspension and redeposition of particles and stirring of the surface sediment by fish and other organisms, the organic matter becomes rather uniformly mixed in the upper layer of sediment. Nevertheless,there usually is a layer of fresh organic matter at the sediment surface that has not been completely mixed into the sediment. Organic matter concentration usually is greatest near the sediment surface (Munsiri et al., 1995). The ratio of labile organic matter to refractory organic matter also is greatest near the sediment surface (Sonnenholzner and Boyd, 2000).Organic matter concentrations in pond soils do not continue to increase indefinitely. If aquaculture practices—e.g., species; stocking, fertilization, and feeding rates; water exchange;amount of mechanical aeration; and treatment of fallowbottom between crops—remain about the same, the annual input of organic matter and rate of organic matter decomposition also will remain about the same (Avnimelech et al., 1984;Boyd, 1995).

第四頁(yè)（最近忙著復(fù)習(xí)考試，大家?guī)兔Ψ�譯下）：
       New ponds usually have little organic matter in bottom soil, and the labile organic matter added each year will largely decompose, while a considerable proportion of refractory organic matter will accumulate (Boyd, 1995). Over a fairly short period, often only four or five crops, organic matter in the soil will reach a high enough concentration that the annualrate of decomposition of organic matter will equal the an nual input of organic matter. At this time, equilibrium will occur and soil organic matter concentrations will remain about the same from year to year.
        Dissolved oxygen cannot enter rapidly in bottom soil because it must diffuse through the tiny, water-filled pore spacesamong soil particles. At a depth of only a few millimeters below the soil surface, the demand for dissolved oxygen by microorganisms will exceed the rate that dissolved oxygen can move to that particular depth, and anaerobic conditions will develop. The oxidized (aerobic) layer of surface sediment will have a lighter color than the deeper, reduced (anaerobic) sediment. The anaerobic sediment usually will be gray or black, and this color results from the presence of ferrous iron.
