The study was conducted in farmersponds located in the northern region of Bangladesh from May 2017 to September 2018 to find out the most suitable combination of Tengra (Mystus vittatus) with other short-cycle fishes. For this reason, combination viz; tengra+pabda+magur+rajpunti+GIFT was considered for trial (with three treatments/combinations and three replications of each) in seasonal farmersponds at 18 upazilas of the greater Rangpur region to evaluate the growth and yield performance of tengra, M. vittatus under a polyculture system. Three different stocking densities of Tengra viz., 500, 600, and 700 with (100 Magur+10 Rajpunti+5 GIFT) were treated as T 1 , T 2, and T 3 respectively. After 5 months of the culture period, (T 1 ) showed significantly (P<0.05) higher production of Tengra (2,035 kg ha -1 ), total production of fishes (5,592 kg ha -1 ), and benefit-cost ratio (1.60) among the treatments These combinations were chosen for multi-location testing (MLT) in different locations of the northern region of Bangladesh. Three locations such as Domar (Niphamari); Kaligonj (Lalmonirhat) and Niphamari Sadar were selected for demon- stration. After 5 months of multi-location testing the trials with Tengra as the main species, the highest production of Tengra (2252 kg ha -1 ), total production of fishes (5656 kg ha -1 ), and benefit-cost ratio (1.65) were found in Kaligonj with significant (P<0.05) difference among three locations. Thus, the results of multi-location trials clearly authenticated the previous findings. Therefore, the technologies of short-cycle fish species should be disseminated to fish farmers and entrepreneurs throughout the semi-arid zone of Bangladesh. ©2023 Agriculture and Environmental Science Academy Keywords Growth Mystus vittatus Production Semi-arid zone Citation of this article: Hasan, K.

The fisheries sector is inseparable from the life and lifestyle of the people of Bangladesh which contributes 4.37% to the national GDP and almost one-fourth (23.37%) to the agricultural GDP (DoF, 2013). About 1.5 million people are directly employed in this sector (DoF, 2012). The rich aquatic biodiversity of the country has been attributed to the world's largest wetlands (Bengal Delta) and three large river systems (Brahmaputra, Ganges, and Jamuna) that flow from the Himala- yan Mountains into the Bay of Bengal. A Huge inland fisheries resource has been supplying fish and other aquatic animals and plants to millions of people living in the Delta (Hossain, 2014). The Northern region (Rangpur division) of Bangladesh is known as a drought and riverbank erosion-prone area. Most of the districts under this division have been experiencing frequent natural disasters and adverse impacts of climate change and surface water has almost disappeared from ponds and canals, ORIGINAL RESEARCH ARTICLE
