夏海黄三元杂种牛生长发育研究

测定分析了夏海黄三元杂交后代（公牛３４头，母牛３７头）与豫北黄牛及海黄Ｆ１初生－２４月龄体尺与体重均较豫北黄牛有较大幅度提高，较海黄Ｆ１提高明显，利用夏海黄三元杂交发展肉牛生产是一条有效途径。     

祁连山水源涵养林综合效能的计量研究

以马克思级差地租理论,建立了祁连山水源涵养林综合效能的评价模型:E=E_d+E_e+E_s;以E与生产投资I的比值为计量水源林的效能指数T,T=E/I。并以祁连山寺大隆森林生态定位研究站实测资料和社会调查数据为计量评价参数,确定其经济评价指标体系和计量系统。结果表明:祁连山水源涵养林综合效能指标为11.93;其中生态效能和社会效能分别是直接经济效能的4.51倍和6.05倍。说明祁连山水源涵养林现行的保护、发展和综合利用的经营方针是正确的。建议河西各受益部门应按水资源效能总收入的0.5％缴作水源林再生产费,以确保国民经济建设的长远发展。

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.     

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.
