Abstract

Rasbora (Rasbora sp.) is one of the endemic freshwater fish species in East Java, which is currently being threatened due to environmental degradation, human activities and pollution. In East Java, it is known that there are several species of Rasbora (Rasbora sp.). Domestication is one method to preserve Rasbora in East Java, preceded by identifying potential species of Rasbora sp. from the natural catchment. This study aims to determine the diversity of Rasbora sp in East Java. Samples were taken at five different locations, specifically: Nganjuk (Brantas Watersheds), Ngawi (Bengawan Solo Watersheds, Silowo Springs Tuban, Umbulan Springs Pasuruan and the Setail Watersheds Banyuwangi. The main parameters observed were morphology and morphometry. The morphological analysis used identification guidelines, while morphometric data were obtained through 15 parameters measurement then analyzed using one-way Anova test on SPSS 25 software. Based on the morphological and morphometric analysis, it is known that the species of Rasbora in Nganjuk and Ngawi regencies are Rasbora argyrotaenia and the species of Rasbora in Tuban, Pasuruan and Banyuwangi regencies are Rasbora lateristriata. One-way Anova test showed Rasbora from the five locations were significantly different based on the result value of p<0.05.
东爪哇省Rasbora的形态计量学和美学分析
Rasbora (Rasbora sp.)是东爪哇特有的淡水鱼种之一,目前由于环境退化、人类活动和污染而受到威胁。在东爪哇,已知有几种拉斯博拉(拉斯博拉sp.)。驯化是保护东爪哇拉斯博拉的一种方法,在驯化之前要从自然集水区确定拉斯博拉属的潜在物种。本研究旨在确定东爪哇省拉氏蝇的多样性。在五个不同的地点采集了样本,具体来说是:恩甘珠克(布兰塔斯流域)、恩加维(班加万索罗流域)、西洛沃泉图班、翁布兰泉帕苏鲁和塞泰尔流域班尤旺吉。观察的主要参数是形态学和形态计量学。形态学分析采用鉴定指南,形态计量学数据通过15个参数测量获得,然后使用SPSS 25软件进行单因素方差分析。通过形态学和形态测定学分析,认为位于Nganjuk和Ngawi地区的拉斯博拉属argyrotaenia,而位于Tuban、Pasuruan和Banyuwangi地区的拉斯博拉属Rasbora lateristriata。单因素方差分析显示,5个地点的Rasbora在p<0.05的基础上差异有统计学意义。
