Validation of the accuracy of household reporting of subsistence fishing catch and effort: a Fijian case study

Abstract  The accuracy of household reporting of subsistence fishing catch and effort and seafood consumption on the Fijian island of Ono-i-Lau was studied. A creel survey was carried out concurrently to validate the household survey data. Reported estimates of fishing participation, effort, and fish consumption were not significantly different to the creel survey estimates. Householder's appeared to overestimate the number of fish from the most abundant family Lethrinidae, and underestimate rarer fish. However, there was no significant difference between the reported and observed contribution of the majority of finfish families and invertebrate taxa. The reported and observed catch rate estimates were not significantly different, indicating that Ono-i-Lau villagers are relatively accurate in their estimation of the number and size of fish from recalled catches.

从机体抗胃肠道线虫的黏膜免疫、胃肠道黏膜的抗原加工与递呈、胃肠道黏膜抵御寄生虫的效应机制等几方面论述了胃肠道线虫的免疫机理和免疫学研究的进展，旨在进一步阐明用免疫介入方法防治胃肠道线虫的理论基础，以解决胃肠道线虫治疗过程中的药物残留以及寄生虫的抗药性问题。     

Growth of triploid oyster, Crassostrea madrasensis (Preston)

The performance of I and II meiotic triploids and control oysters (Crassostrea madrasensis) reared at Tuticorin Bay was compared to determine if the improvements in the growth of edible oysters were additive to faster growth in triploids. After a grow‐out period of 12 months, both mean whole weights and shell heights were in order I meiotic triploid>II meiotic triploid>control. Mean whole weights and shell height of different oyster lines were all significantly different (P<0.05). On an average, larger morphological traits indicated that growth improvements from triploids were additive, and throughout the study triploid oysters maintained faster growth rate than their diploid siblings. Condition index and adductor muscle diameter of both triploids were higher than those of control.     

人工饲养条件下荒漠猫的饲养与繁殖管理

在人工饲养条件下,通过模拟野外栖息环境,加强科学饲养管理,成功繁殖荒漠猫的饲养管理方法和荒漠猫的发情、交配、妊娠、哺乳等繁殖行为。同时对在西宁动物园产下并成活的3只幼猫的体尺、体重、形态和行为的变化进行了描述。     

高产奶牛福利

近20年，荷斯坦牛成为优势奶牛品种，营养改善促使奶牛产奶量大幅度增加，工厂化管理致使奶牛运动量减少、生产性疾病频发，奶牛康乐受到严重威胁，因此，改善高产奶牛福利的呼声高涨。本文以生产性疾患为中心，从规模化生产、遗传改良、畜舍环境等角度讨论了高产奶牛的福利问题。     

沙土区薄壁连拱护岸墙试验与应用

沙土区薄壁连拱护岸墙为悬臂式支撑、薄壁连拱无底板结构，拱板中间采用无砂砼排水孔的钢筋砼肋形预制板，冲沉法施工，造价低廉；外形美观，抗倾、抗滑性能强。该墙为平原沙土区河道水土保持及修复找到了一条经济合理、施工方便、简便易行的护坡办法，具有较高的实用价值和广阔的推广使用前景。     

台江采育场竹木混交林丰产措施试验

对台江林业采育场现有竹木混交林进行施肥和土壤垦复两种试验，结果表明，不同施肥处理虽有一定增产效果，但经方差分析未达到显著水平；不同土壤垦复措施的增产效果，以深翻加施肥的新竹产量最高，锄草松土居第二，单纯深翻并不理想，效果不如劈山抚育。因而，新兴竹木混交林应以调整竹林结构和护笋养竹为主，每年锄草松土即可达到材用丰产林标准，不宜盲目深翻、施肥。     

基于插值法的静止无功补偿计算机控制

依据电力系统的近似数学模型，提出了适用于稳定供电电压的无功电压控制曲线。在此基础上，论述了应用插值公式的静止无功补偿计算机控制方法。该方法应用简便，具有较好的动静态特性。
