An experiment was conducted in eighteen 200-m2 fertilized earthen ponds at the Asian Institute of Technology, Thailand, from March through October 2000. This experiment was designed to assess the efficiency of snakehead (Channa striata) in controlling recruitment of mixed-sex Nile tilapia (Oreochromis niloticus) in ponds and to assess growth and production characteristics of Nile tilapia in mon...

Submitted: May 17, 2013; Accepted: Jun 26, 2013; Published: Jun 30, 2013 Abstract: The study was conducted to see the feasibility of raft aquaponics in polyculture pond. Three experimental ponds (with an area of 5.2, 3.12 and 3.12 decimal) were selected where the third one was considered as control pond. Locally available cheap materials were used in preparing rafts, e.g., bamboo splits, iron w...

The amount of PM bound by tree canopies depends on leaf traits, but also the area available, both which are dependent identity. We investigated four species (Acer platanoides L., Tilia cordata Mill., Quercus robur Carpinus betulus L.) grown in monocultures and two polycultures. leaves these was determined washing fractionation into PM2.5, PM10 PM100 size classes using a filtering method. index ...

Constructed wetlands have emerged as a viable alternative for secondary treatment of domestic wastewater in areas with landscape limitations, poor soil conditions, and high water tables, which limit installation of full-scale adsorption fields. Existing information on the effects of macrophytes on treatment performance is contradictory and mostly derived from greenhouse mesocosm experiments. Th...

Experiments were conducted to assess the effects of polyculture on tilapia growth and to evaluate African catfish (Clarias gariepinus) as a predator control for unwanted tilapia offspring in a polyculture system. Three treatments were tested using nine 200 m earthen ponds. Ponds were stocked with male tilapia in treatment 1 (Tl), mixed sex tilapia in treatment 2 (T2), and mixed sex tilapia and ...

Fermentation-based chemical production strategies provide a feasible route for the rapid, safe, and sustainable production of a wide variety of important chemical products, ranging from fuels to pharmaceuticals. These strategies have yet to find wide industrial utilization due to their inability to economically compete with traditional extraction and chemical production methods. Here, we engine...

This study aims to determine the management system of polyculture pond business, analyse revenue and income feasibility a business. The methods analysis used are descriptive, analysis, analysis. results showed that Polyculture Pond Business was carried out using semi-intensive with mixed in same pond, production costs incurred by per hectare were IDR 20,110,213/6 months, all expenses together, ...
