Abstract Inland aquatic ecosystems cover 0.1%–3.0% of Earth’s surface. They provide different ecosystem services to the area, such as drinking water, transportation, and hydropower generation. However, increasing land use changes threaten their ecological integrity. This study aims to assess land use and land cover change and their impact on stream...

The study was conducted to investigate the breeding season, sex ratio, size at maturation, fecundity, and condition factor of African catfish Clarias gariepinus in Lake Koka. A total of 754 fish specimens were collected from October 2020 to August 2021. Total length and weight were measured and sexes were identified and gonad maturity levels were r...

The Afar region is characterized by an arid and semi-arid climate with erratic rainfall and is prone to frequent droughts despite being endowed with fresh and saline water bodies along the Awash River Basin. Lake Hertale is one of those fresh water bodies located in the middle of the Awash River Valley. The lake's fishery is presumed not to have be...

Aquaculture is one of the fast-growing industries which largely relies on the introduction and use of non-native species. This forms a paradox: on one hand, some species were significantly contributed to the fast expansion of aquaculture, while others were negatively affected due to unregulated and irresponsible use of non-native species. Although...

Specific concepts of fluvial ecology are well studied in riverine ecosystems of the temperate zone but poorly investigated in the Afrotropical region. Hence, we examined the longitudinal zonation of fish and adult caddisfly (Trichoptera) assemblages in the endorheic Awash River (1,250 km in length), Ethiopia. We expected that species assemblages ar...

The present study was conducted to share the experience of promoting fish production and marketing from the Tendaho Reservoir of the Afar region, Ethiopia. The study results indicate the reservoir is serving its purpose, namely to generate gainful employment for the pastoralist youth and to create sustainable livelihoods and sources of income for t...

Evaluation of integrated agriculture aquaculture (IAA) was conducted on station in the National Fisheries and Aquatic Life Research center (NFALRC), Sebeta. In this trial the effect of irrigation with pond water and spring water and application of inorganic fertilizer on yield and other parameters for Tomato (Lycopersiconesculentum) and potato (Sol...

Despite the importance of fish production and marketing as one viable means of livelihood diversifications in the pastoral areas of Ethiopia, this sector has not received the required institutional, financial and policy support. This article shares the experience of promoting fish production and marketing in the pastoralists and agro-pastoralists a...

A value chain is a sequence of related enterprises (operators) conducting activities (functions) so as to add value to a product from its primary production, through its processing and marketing, to the final sale of the product to consumers. The main objectives of this research was to understand fish value chain in Lake Tana and to point out the p...

The study was conducted to assess the impact of agricultural and industrial wastes on the distribution and relative abundance of fish along the upper Awash River Basin. Fishes were collected using electrofishing apparatus from three sampling sites along the river representing different levels of anthropogenic impacts on the river. A total of 1912 f...

Isolation and identification of pathogenic fungi from African Catfish (Clarias gariepinus) eggs and adults in Ethiopian National Fishery and Aquatic Life Research Center hatchery was conducted from October 2015 to May 2016. The aim of this study was to investigate the aquatic fungal flora associated with eggs and brood stock from African catfish in...
