Abstract
The research was carried out with small indigenous fish species (SIS) named mola (Amblypharyngadan mola) in monoculture system to intensify production in farmers’ homestead ponds with 50% household women involvement during June to December, 2016. Brood mola was stocked at the rate of 2, 4 and 6 m-2 with three replications in each treatment. Supplementary feed (27.1% protein) consisted of commonly available agricultural by-products was provided daily at the rate of 2% of the total biomass along with natural feed as mola is planktivorous species. Seven different water quality parameters were measured fortnightly and found within cultivable range. Gross production of mola were obtained 520.59±23.4, 599.06±258.87, 1063.94±42.87 kg ha-1 from T1, T2 and T3, respectively after 4 months’ culture period. The yield of T3 was significantly greater (P < 0.05) than T1 and T2. The highest gross production was obtained in T3 where stocking density was 6 brood mola m-2.

Highlights
Bangladesh is a small dense populated country where protein demand is increasing with population inflation
Brood mola were collected from the homestead pond of local farmers of Batiaghata Upazila, Khulna in August 2016
Water quality parameters were analyzed to observe any appreciable changes that might have occurred in response to different treatments
Summary
Bangladesh is a small dense populated country where protein demand is increasing with population inflation. Small indigenous species (SIS) are enrich with micronutrients like vitamins and minerals. Small indigenous species like Amblypharyngodon mola, nationally known as Mola is important component in the diet of the rural people in Bangladesh (Roos et al, 2002), which is an important source of protein and rich source of a range of other essential nutrients. Vast number of small seasonal ponds in Bangladesh are often owned by poor or marginal farmer are typically underutilized resource for fish production which are a natural habitat for Mola and potentially suitable for its culture (alone or in combination with other species) (Roos et al, 2002). Monoculture of “mola” in homestead ponds to increase nutritional and economic benefit for the rural poor
