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.

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。

加入WTO对反腐败斗争的影响及对策思考

加入世贸组织总体上对我国的反腐败斗争是有利的。但由于西方国家对我国进行外部渗透和影响的机会增多;我国经济、政治等体制改革的不彻底;入世初期的接轨工作难以到位;高智化、国际化、团伙化的犯罪特点;新一轮资产重组等原因，存在着腐败滋生蔓延的必然条件，新的腐败犯罪的高发期还可能出现。为此，我们要坚持依法治国，加强法律、法规建设，加快政治体制改革，强化办案职能，严肃查处各种腐败犯罪，加大对国有资产监管的力度，依法治权，依法行政，完善党内各项运行机制，从源头上预防和治理腐败;加强思想教育，提高党员干部素质，增强拒腐防变的能力，自觉抑制腐败;密切国际间的相互协调与合作，共同打击腐败。
