Abstract

Abstract The physico-chemical parameters, plankton and macro-benthic invertebrates of the Lagos Lagoon (Badore, Ajah), Lagos State, Nigeria were studied between February and July 2018 at four sampling stations in a disparate range of human activities and impact. The result of phytoplankton analysis indicated a total of 56 genera with 40 genera within Bacillariophyta, accounting for 72% of the abundance. Zooplankton comprised 26 genera with 82% of the abundance of crustacea. The benthic macroinvertebrates were composed of mollusca, arthropoda and annelida. Results also indicated that the main drivers affecting the abundance and distribution of planktonic and benthic invertebrates were water temperature, pH, TDS and EC. The monthly variations of physico-chemical parameters in the Lagoon could be the result of human activities associated with transportation, fishing and domestic sewage disposal from the surrounding settlements. Therefore, it is necessary that relevant authorities keep in check some of these activities around the Lagoon as well as educate the population on the necessity for the conservation of these water resources.

人为因素对尼日利亚拉各斯泻湖浮游生物和底栖生物群落的影响

摘要2018年2月至7月，在不同的人类活动和影响范围内，在四个采样站对尼日利亚拉各斯州拉各斯泻湖（Badore，Ajah）的物理化学参数、浮游生物和大型底栖无脊椎动物进行了研究。浮游植物分析结果表明，硅藻门共有56属40属，占总丰度的72%。浮游动物共有26属，占甲壳纲动物丰度的82%。底栖大型无脊椎动物由软体动物、节肢动物和环节动物组成。结果还表明，影响浮游和底栖无脊椎动物丰度和分布的主要驱动因素是水温、pH、TDS和EC。泻湖物理化学参数的月度变化可能是与运输、捕鱼和周围定居点生活污水处理相关的人类活动的结果。因此，有关当局有必要控制泻湖周围的一些活动，并教育民众保护这些水资源的必要性。

期刊介绍： The Croatian Journal of Fisheries was established in 1938 and today possesses a long-term tradition of publishing papers that deal with both freshwater and marine fisheries. Areas covered by the Journal include ichthyology, aquaculture, ecology and diseases of fish and other aquatic organisms, problems of open waters and other topics related to the fisheries field. Prior to publication, articles pass through rigorous review by senior scientists from around the world. The Journal features articles that reflect original research, interpretative content and subject matter of interest to the fisheries profession.
