“…Based on the results found, it shows that the index value of phytoplankton diversity in Ranu Grati waters is 1.4-2.6 and the value of zooplankton diversity has a range ranging from 1.1-1.9, which indicates that the diversity of plankton species is moderate. According to Shannon-Wiener, there [Ochieng et al, 2021]. In addition, the uniformity index of the phytoplankton found has a range ranging from 0.883 to 0.975, and the uniformity of zooplankton has a range ranging from 0.898 to 1, which indicates that the plankton uniformity value has high species uniformity.…”

The Lempuk fish (Gobiopterus spp.) is a kind of fish that is exclusively found and inhabits the Ranu Grati area in Pasuruan Regency. The Lempuk fish is a prominent tourist attraction and is frequently targeted for fishing due to its significant economic significance. This leads to excessive exploitation, resulting in population decline and posing a threat to its sustainability. Therefore, it is necessary to identify the abundance and type of plankton, as well as its relationship with the study of stomach contents, to gather supporting data for future domestication efforts. The sampling was conducted three times, with a two-week gap, at five distinct sites. The research employed a quantitative-descriptive approach and the sampling a purposive sample technique. The research findings revealed the presence of four distinct classes with 20 different species in the phytoplankton community, as well as four distinct classes with 12 genera in the zooplankton community. The study of stomach conten this fish shows, primary diet of this fish, as shown by their propenderence index, consists of phytoplankton from the Asterionella species and zooplankton from the Daphnia genus.

“…For instance, while SASS was developed for assessing water quality and the ecological condition of South African rivers (Dallas, 1997;Chutter, 1998;Dickens and Graham, 2002), version five of SASS (SASS5) has been applied without modification in other countries in southern and eastern Africa, including Zimbabwe (Bere and Nyamupingidza, 2014;Mwedzi et al, 2016), Swaziland (Mthimkhulu et al, 2004) and Kenya (Oigara and Masese, 2017;Mbaka et al, 2014;M'Erimba et al, 2014). Similarly, TARISS, which is a modified version of SASS5 developed for assessing streams and rivers in Tanzania, has recently been applied in Rwanda (Dusabe et al, 2019) and Uganda (Tumusiime et al, 2019;Turibamwe and Wangalwa, 2020;Ochieng et al, 2021) without modifications. Similarly, while some MMIs have been tested and validated for monitoring of some of the African aquatic ecosystems (e.g., Raburu and Masese, 2012;Moges et al, 2016;Tampo et al, 2020;Achieng et al, 2021;Kaboré et al, 2022), some have been used without validation, including Toham and Teugels (1999), Masese et al (2009a), Aura et al (2010), Alemu et al (2018) and Aura et al (2021).…”

Many streams and rivers outside conservation areas across the Afrotropics face multiple stressors from land use change, urbanization, and excessive water withdrawals. Thus, there is a need to develop cost-effective tools for assessing and monitoring ecological changes to inform management decisions. Studies utilizing macroinvertebrate communities as indicators of the ecological condition of streams and rivers in the Afrotropics use diverse methods, including diversity, richness, biotic and multimetric indices. However, some of these indices are region- or country-specific, which limits their general use across multiple regions or countries. In this study, we address this challenge by testing and comparing the performance of diversity and richness indices (e.g., Shannon-Wiener and Simpson), regional biotic indices (the African Scoring System Version 5 [SASS5], Tanzanian River Scoring System [TARISS] and a biotic index developed for the Ethiopian highlands [ETHbios]), and a macroinvertebrate-based index of biotic integrity (M-IBI) in assessing the ecological condition of Afrotropical rivers with the transboundary Mara River, Kenya and Tanzania, as a case study. In this study, we analyzed water and habitat quality degradation caused by multiple stressors such as land use change, organic pollution and flow alteration and the corresponding responses in macroinvertebrate communities. We utilized macroinvertebrates data collected from 143 sites covering the entire gradient of the river and its major tributaries in Kenya and Tanzania. To develop the M-IBI, we used 12 metrics that describe macroinvertebrate community richness, composition, tolerance to disturbances (indicator taxa), and the composition of functional feeding groups. Although all the biotic indices were sensitive to poor water quality and human disturbance of the river, the M-IBI performed better than biotic indices (SASS5, Tanzanian River Scoring System, and Ethiopian highlands), diversity and richness indices by having a higher discriminatory ability of site categories according to different levels and types of disturbance. Diversity and richness indices performed poorly and failed to discriminate between stressor gradients in the river. This study demonstrates a need for testing and evaluating indices or protocols before adoption and use in biomonitoring streams and rivers in other countries and regions. There is an even greater need to assess the tolerance of macroinvertebrate taxa before inclusion in biotic indices for improved performance as discriminators of multiple stressors.
