项目摘要
Between the end of September, 1994 and the end of January, 1995, three Japanese researchers and one Zairean researcher, Department of Fisheries, Mpulungu, Zambia, which locates the southernmost end of Lake Tanganyika, to conduct cooperative research of Lake Tanganyika between Japan and Zaire. Since implementation of the research in the Zairean and Burundian water was not possible for inter-tribe battles, the research was done in Zambian water, with cooperation with Zambian fisheries research officers at Mpulungu.The purpose of the research is to elucidate the mechanisms to maintain the fascinating biodiversity of Lake Tanganyika. Social structure, feeding behavior and geographical morph variation of algal feeding herbivorous cichlid fishes were studied in rocky littorals near Mpulungu. Distribution of Atyidae prawns was also studied in the rocky littoral area.Territoris of the genus Petrochromis species were maintained against congeneric fish. Their territories were occupied compactly … More almost all area of shallow rocky littoral. Males of Petrochromis polyodon occupy their territory neighboring with conspecific females or smaller congeneric fish, but never occupied territory with conspecific males side by side. When a male of P.polyodon was removed experimentally, its territory was taken over by the nearest conspecific male by expansion or a new immigrant of conspecific male, but never occupied by the neighbor nor a new immigrant of other congeneric species. This result suggests that intraspecific male-male aggression of P.polyodon is responsible for the maintenance of territory separation, and furthermore interspecific small habitat separation seems to facilitate coexistence of other congeneric species.Algal feeder cichlids of other genera can come in and feed on attached algae on stone in the territories of Petrochromis fish. It is hypothesised that they are permitted by Petrochromis fish by using different resource of algae which Petrochromis fish do not use. In this hypothesis underwater observations of the feeding behavior of the genera Telmatochromis and Simochromis fish were made. Fish collection of these genera were also made. Analyzes of feeding habit and mouth morphology are underway.Atyid prawns are important food organisms for benthivorous cichlid fish. Distribution of atyid prawn in the littoral rocky area was studied by pulling a net, setting traps and scooping a dipnet underwater. Analysis of the collecting specimens is underway. Less
1994年9月底至1995年1月底,位于坦噶尼喀湖最南端的赞比亚姆普伦古渔业部的3名日本研究人员和1名扎伊尔研究人员对日本和扎伊尔之间的坦噶尼喀湖进行了合作研究。由于部落间战斗不可能在扎伊尔和布隆迪水域进行研究,因此在赞比亚水域与姆普龙古的赞比亚渔业研究官员合作进行了这项研究。研究的目的是阐明维持坦噶尼喀湖迷人生物多样性的机制。研究了姆普伦古附近岩质海岸藻类摄食草食性唇形鱼的社会结构、摄食行为和地理形态变化。对岩质海岸地区的对虾的分布也进行了研究。属的对虾与同类鱼类保持了领地。他们的领土被紧紧地占领了…更多的地区几乎都是滨海浅层岩石。多齿多齿罗非鱼雄鱼与同种雌性或体型较小的同种鱼相邻占据其领地,但从不与同种雄性并排占据领地。当一只多齿龙雄性被实验性地移走时,它的领地会被最近的同种雄性通过扩张或一只同种雄性的新移民接管,但不会被邻居或其他同属物种的新移民占据。这一结果表明,多齿罗非鱼的种内雄性攻击性是维持领土分离的主要原因,而种间小生境分离似乎促进了其他同类物种的共存。其他属的食性叶蝉可以进入并捕食Petrochromis鱼领土上附着的藻类。假设它们是通过使用不同的藻类资源而被Petrochromis鱼允许的。在这一假说中,对端色属和同色属鱼类的摄食行为进行了水下观察。对这些属的鱼类也进行了采集。对虾的摄食习性和嘴部形态的分析正在进行中。对虾是食底性慈鱼的重要食物生物。采用拖网、诱捕、挖网等方法,对滨海岩区对虾的分布进行了研究。对收集到的标本的分析正在进行中。较少
