Field experiments to improve the efficacy of gargoor (fish trap) fishery in Kuwait's waters

Fish traps were investigated to understand the effects of season, bait type, trap size, and trap soak time on catch rates, catch composition, and trap loss rates from March 2004 to September 2005, to improve the performance and management of Kuwait＇s gargoor （cage style fish trap） fishery, which used to be the nation＇s most important one in terms of value and landings volume. Catch rates were the highest in April/May （5 8 kg/trap haul） and again in December （7 kg/trap haul）. Bait type and trap size also affected catch rates and species composition. Of the seven baits tested, the best catch rates, 〉5 kg/trap haul, occurred with cuttlefish （Sepia pharaonis）, but wolf-herring （Chiroeentrus dorab） and mullet （Liza klunzingeri） also produced good results （4-5 kg/trap haul）. Within the five tested sizes, the two largest-sized traps captured more fish and larger size fish. Analysis of variance （ANOVA） showed significant differences of catch rate among traps with different baits as well as among traps of different sizes. Duncan test further revealed these differences between two specific baits and sizes. Cluster Analysis of species composition showed more differences among different baits than among different trap sizes. Longer soak times did not result in larger catch rates, but increased trap loss. About 10-day soak time resulted in trap loss 7%, while 40-day soak time could result in a loss of around 20%. Consequently, it is recommended that the gargoor be checked every 10 or fewer days. The average overall catch rate during the study period was lower than that of 1980s （4.5 vs. 5.8 kg/trap haul）, indicating a possible decline offish abundance in Kuwait＇s waters. It is recommended that the number of gargoor fishing boats and gargoors from each boat should be limited to allow stock rehabilitation.

Trapping Efficacy of Two Types of New Sex Lures for Athetis lepigone (Moschler) in Fields

[Objective]The paper was to compare trapping efficacy of two types of new sex lures for Athetis lepigone（Moschler）in fields.[Method]The trapping performance of two lures for A.lepigone was tested in Hongdong County of Shanxi Province of China from June 21 to August 20 in 2012.[Result]The average number of moths trapped by lure B was 2.49 times of that trapped by lure A during June 21and August 17,and the difference was significant.The maximum number of A.lepigone moth trapped by lure B at one basin within a single day reached 280,while that trapped by lure A was only 85.The validity of two lures in fields reached 58 d,basically consistent with seasonal dynamics of A.lepigone moth trapped by lures.[Conclusion]Lure B is of higher quality and could be recommended to apply in dynamic monitoring and trapping control against A.lepigone adults.

Clinical observation on therapeutic effect of acupuncture for chronic functional constipation

Methods Two Qihai （气海 CV Objective To discuss the efficacy of acupuncture for groups of points were applied alternatively to 90 cases by chronic functional constipation acupuncture： （1） Tianshhu （CFC）. ST 25）, 6）, Shemgjfuxu （上巨虚 ST 37）, etc. （2）Zhongliao （中髎 BL 33）, Xiadiao （下髎 BL 34）, Dachangshu （大肠俞 BL 25）, etc. Electroacupuncture was applied in combination at Zhongliao （中髎 BL 33）, Xialiao （下髎 BL 34）, Tianshu（天枢 ST 25） and Shamgjuxu （上巨虚 ST 37）, once a day, 10 treatments made one session. By constipation diary of patients, frequency of going to stool, straining severity, time of once bowl evacuation, a sense of incomplete bowel emptying, stool quality, a sense of defecation and the Patient Assessment of Constipation Quality of Life questionnaire （PAC-QOL）, as well as the changes before and after treatment were observed. Results After treatment, the apparent improvements were achieved in frequency of going to stool, straining severity, time of once bowl evacuation, a sense of incomplete bowel emptying, a sense of defecation and score of PAC-QOL as compared with those before treatment （all P〈0.01）. The total effective rate was 67.7% （61/70）. The acupuncture effieacies were various on CFC of different dynamic mechanisms. The efficacy on slow transit constipation （STC） was superior to that caused by spastic pelvic floor syndrome （SPFS-C） （P〈0.05）, the efficacy on constipation caused by irritable bowel syndrome （IBS-C） was superior to that on either SPFS-C or constipation caused by relaxant pelvic floor syndrome （RPFS-C） （both P〈0.05）. Of 52 eases in effective follow-up, 1 month after treatment, 3 eases were cured, 6 eases markedly effective, 23 eases effective, and 20 cases failed; 3 months after treatment, 3 eases were cured, 5 eases markedly effective, 16 cases effective and 28 cases failed. Conclusion Acupuncture has definite efficacy on CFC with definite etiology, loci and diagnostic classification. But, the efficacies are different due to various dynamic mechanisms. A further optimized treatment program is required to improve the efficacy on SPFS-C and RPFS-C.
