Spatio-temporal distribution of sergestid shrimp Acetes intermedius in the coastal waters of southwestern Taiwan

SUMMARY: Spatio-temporal variation of the sergestid shrimp Acetes intermedius in the coastal waters of southwestern Taiwan was investigated based on 1546 samples collected by 13 commercial fishing vessels from July to October 1996. Adult sergestid shrimp started a down-estuary migration with the increased river discharge associated with heavy summer rainfall. Fishing season for this species was to commence after that. In July, the shrimp stock was found on the shallow continental shelf off Tungkang and Fangshan. They mainly aggregated in Kaoping Canyon off Tungkang during August and September occurring at very high densities. In October, the shrimp returned to the coastal waters off Tungkang and Fangshan at lower densities. The heavy rainfall is a factor that triggers the shrimps to make a down-estuary migration that could reduce competition for food between adults and their offspring during the period of high river discharge. When the northeast monsoon prevailed, the sergestid shrimp moved back to the estuaries and the fishing season was terminated.

Migration of kawakawa Euthynnus affinis in the waters near Taiwan

ABSTRACT:   Kawakawa Euthynnus affinis is the most abundant species among the small tuna in the coastal waters of Taiwan. The migration pattern of kawakawa to Taiwan was determined in the present study based on the species' feeding habits and reproductive biology and on temporal variation of catch for kawakawa and its prey fishes. Schools of this species successively migrate to Taiwan from September to May, and then move away in June. They travel to the waters off Taiwan with the warm Kuroshio current, migrate toward coastal waters for feeding and move away for spawning. It is suggested in the present study that the kawakawa spawning ground is in the waters of the northern Philippines. The migration of kawakawa exhibits size-segregating behavior. Schools of immature young fish first arrive in the coastal waters around Taiwan, followed by the adults.

中国台湾地区森林疗愈发展计划及其内容

发展森林康养是新兴的森林可持续经营方式,是缓解现代社会压力有效而简捷的措施,也有助于弥补预防医学领域的短板。发展全民健康养生和森林康养产业是时代所趋,同时也符合乡村振兴战略的目标。文中以中国台湾地区“林务局”编写的《森林疗愈发展策略暨行动计划书》为基础,重点梳理台湾地区森林疗愈计划的内容,包括“森林疗愈的发展趋势”“森林疗愈场地选址原则”“森林疗愈课程与运营规划”“森林疗愈发展策略方案”4项议题;总结森林疗愈发展的过程、内容和进展,目的是为进行森林康养规划、编制相关经营计划以及调整研究方向提供参考。     

闽东北外海渔场中上层鱼类探捕调查研究

为了减轻福建近海的捕捞压力，打破灯光围网作业生产的被动局面，解决闽南－台湾浅滩渔场在春夏汛灯围淡季作业问题，于１９８９￣１９９１年５￣９月，对该渔场的中上层鱼类进行生产性探捕。在专业生产调查中，从统计的渔获量和其它方面，取得了较好的经济效益和社会效益，这期间表明：闽东北外海渔场中上层鱼类有开发利用价值，不仅为福建灯光围网作业开创一条新路，而且为今后重点开发该渔场提供科学依据。
