海洋生物调查是海上调查的重要组成部分,主要任务是查清海区生物的种类组成,数量分布等。本文简要介绍了海上浮游生物调查的调查工具和设备,以及样品取样保存方法,并对秦皇岛近海岸所取样品进行定性定量分析。调查结果显示秦皇岛近海岸浮游植物中卵形隐藻、普通小球藻、端尖曲周藻为优势种。浮游植物平均细胞密度为766 837.5个/L,生物量为7.674 951mg/L,浮游生物量为富营养型水质,为以后治理水体富营养化提供一定参考。 相似文献

海绵拥有许多在结构上非常多样化的生物活性物质,是最具有药物开发潜力的海洋生物资源。但是海绵资源的供给问题限制了海绵生物活性物质的开发。科研人员采取了多种策略以解决这个药源海绵的生物资源供给问题,多年实践表明海区原位移植可能是短期内最具有可行性的策略。本文对近20年来全球药源海绵的海区原位移植实践进行综述,总结出包括移植方式、食物、移植块大小、水流和深度等海绵原位移植的要点,并指出了原位移植操作并不影响海绵中生物活性物质的含量。结合本课题组的研究进展,我们认为在我国开展大规模的海区原位移植来解决海绵资源供给问题是完全可行的,并提出了在未来实践中要注意克服的几个问题。 相似文献

东山湾渔业环境监测调查报告 总被引:1,自引:1,他引:1
东山湾渔业生态环境优良,生物资源丰富,近年来已发展成为我省的重要渔业养殖基地,其综合开发规划经列入国家”星火计划”。 然而该处在大力开发的同时,也出现不少问题,其中一个主要问题就是局部养殖海区水质污染严重。水质污染或来自人为原因,如陆上生活污水、工厂排污、农田灌溉、码头船只油 相似文献

<正>近年来南戴河海域浅海养殖业发展迅速,浅海筏式养殖规模已达750万笼,建设人工鱼礁800hm2,投入礁体50万空立方,底播养殖底栖贝类233hm2。分别进行了海湾扇贝、刺参、魁蚶增养殖开发,由于上述增养殖品种都依靠海区天然饵料生长,而海域流场作为水体交换重要因素之一,决定着能否为养殖品种提供充足天然饵料,从而决定着本海区养殖方式、养殖品种、养殖规模、放养密度等。为了做好本海域养殖规划,合理利用养殖水面,避免盲目开发造成经济损失,我们会同秦皇岛 相似文献

摩洛哥在国家管辖下的海区生物资源蕴藏量以及渔获量方面,均居于阿拉伯国家中的首位。1980—1988年间,摩洛哥韵海产品渔获量增长了二倍,产值增长近七倍。预计这一增长速度将能保持到90年代。根据初步预测:1990年的总渔获量约有68.02万吨;1991年将增至73.46万吨;1992年为79.34万吨。 相似文献

Recent years have witnessed a rise in sensitivity towards protection of natural genetic resources and the environment at the
international level. This is evident from the implementation of the convention on biodiversity (CBD). To conserve and optimize
utilization of its bioresources, India enacted the Biological Diversity Act 2002. The conservation and management of aquatic
resources is important for sustainable utilization of fisheries potential for the economic advancement of farmers and fishery
workers, today as well as for posterity. As the biotechnological and genomic revolutions are ready to take off, the sovereign
rights of native inhabitants to intellectual property rights (IPR) related to aquatic genetic resources and associated traditional
knowledge are also integral components of management strategies for genetic resources. 相似文献

根据2013年春季、夏季和秋季对辽东湾近岸表层海水重金属的调查数据,分析了该调查区域海水重金属浓度的季节变化,并运用内梅罗(Nemerow)指数法和综合质量指数法对该海域海水重金属污染状况进行了综合评价.结果显示,辽东湾调查海域表层海水中重金属浓度夏季最高,仅Pb超过第一类海水水质标准,且Pb的站位超标率为66.67%.按照美国国家海洋与大气管理局(National Oceanic and Atmospheric Administration,NOAA)推荐的海水中重金属生物慢性安全浓度下限,仅Cu在个别站位的浓度高于NOAA推荐的生物慢性安全浓度下限,其余所有元素的浓度均未超出,不会对生物体产生显著影响.内梅罗指数法和综合质量指数法评价结果显示,辽东湾调查海域属于清洁-轻污染等级,水环境分级属于尚清洁-允许级别,重金属污染较重的区域主要有3个,分别是绥中近岸海域、辽东湾北部河口区、复州湾和金州湾近岸海域. 相似文献

闽东北外海蟹类种类组成 总被引:1,自引:0,他引:1
本文根据1998—1999年在闽东北外海进行四个季度月的蟹类资源定点调查及相关资料,研究调查海区蟹类种类组成。结果表明:本调查海区蟹类组成有51种,隶属11科34属,以暖水性种类为多,具有热带与温带群落之间的过度性混合群集特点,主要渔获种类有细点圆趾蟹、光掌鲟、锈斑鲟等10种;其中细点圆趾蟹是本调查海区最主要渔获种类,主要分布于水深100—120m的海域,渔获量占蟹类总渔获量的54.4%,尚有一定资源潜力,待于合理开发利用。 相似文献

1. The impact of land-claim on the intertidal areas of the Forth estuary, eastern Scotland is described. It is shown that in recent times almost 50% of the intertidal area has been destroyed for a variety of purposes, including agriculture, harbours and industrial development. 2. The loss of infaunal invertebrate biomass and production from the intertidal habitat has been calculated for each part of the estuary, and by summation for the whole estuary. The loss is discussed in relation to the total biomass and production, both intertidally and subtidally, of the estuary. It is shown that proportionately more biomass and production may have been lost than area. 3. The impact of land-claim on estuarine fish is calculated. Land-claim has removed 24% of the natural fish habitats in the Forth estuary, and thereby removed 40% of their food supply. 4. The impact of habitat loss on birds was observed for one area where observations continued throughout a period of land-claim. For individual bird species at Torry Bay, land-claim had consequences ranging from neutral to substantially negative. Significant declines were found for overwintering populations of dunlin and bar-tailed godwit. Comparisons of pre- and post-land-claim bird feeding usage of this area, showed that the impact of land-claim on local bird populations differed between species. The large scale loss of habitat on the Forth seems likely to have reduced the size of some shorebird populations which overwinter on the estuary. 5. It is concluded that when considering the impact of land-claim on estuaries that, as found in some previous studies, a simple consideration of area lost may be inadequate to describe the effects of land-claim, and the consequences for animals living within the estuary may differ considerably amongst themselves and from area to area. 相似文献
