摘要

这项研究调查了拉各斯州巴达格里Ilaje渔业社区的渔业。调查了鱼种组成、长度-重量关系、着陆点、渔具和渔具的相关参数、渔后技术和渔民的社会经济状况。2017年7 - 12月,每两周采集一次物种样本,采用结构化问卷方式采集样本,并与关键信息提供者和焦点小组进行讨论。22科36种鱼类的斜率(b)值在-1.5826 ~ 8.4126之间,大部分鱼类呈负异速生长。条件因子K (K)以瘦毛鼠(毛鼠科)最低,为0.321,以红毛鼠(毛鼠科)最高,为20.304。大多数独木舟由40马力的发动机驱动,捕获的鱼类使用传统的烟窑保存,渔民的社会经济地位一般/低。在尼日利亚拉各斯州Badagry的Ilaje渔业社区上岸的一些鱼种的长度和重量测量分析结果尚未报告,可供进一步研究参考。

Fisheries of Ilaje Community, Badagry, Lagos, Nigeria
This study examined the fisheries of Ilaje Fishing Community, Badagry, Lagos State. The species composition, length-weight relationships, correlation parameters of landings, fishing gears and crafts, post-harvest technology and socio-economic profile of Fishermen were investigated. Species were sampled fortnightly from July to December, 2017 and respondents were sampled with structured questionnaire and discussion with key informants and focused group. The slope (b) values obtained for the 36 fish species from 22 families ranged from -1.5826 to 8.4126 with most of the fish species having negative allometric growth. Lowest condition factor (K) (0.321) was recorded in Trichiurus lepturus (Trichiuridae) while the highest value (20.304) was observed in Calappa rubroguttata (Calappidae). Majority of the canoe are motorized by 40 horse powered engine, with the fish species captured preserved with the use of traditional smoking kiln, while socioeconomic status of the fisherfolks is concluded to be average/low. Output of analyses of length and weight measurement of some species, which were landed in Ilaje Fishing Community, Badagry, Lagos State, Nigeria, which have not been reported, are available for referrer for further studies.
