Evaluation of provitamin B1 as agent to reduce feed cost of practical diet of the nile tilapia and milkfish

Aquafeeds / By

DOST-PCAARRD, in partnership with the University of the Philippines Visayas-National Institute of Molecular Biology and Biotechnology (UPV-NIMBB) conducted a feeding trial wherein the project team supplemented benfotiamine in the tilapia’s diet. Benfotiamine is a derivative of Vitamin B1 (Thiamine) which improves carbohydrate utilization in diabetic human subjects. Since most, if not all, aquatic animals are …

Pilot test on incorporating the filamentous green algae Rhizoclonium riparium in the diet of Nile tilapia

Aquafeeds / By

UPV conducted pilot tests on incorporating the lumot or Filamentous Green Algae Rhizoclonium riparium in the Diet of Nile Tilapia. They evaluated whether or not the incorporation of Rhizoclonium meal into the diet of tilapia in two farm areas increases profitability. They also refined feeding scheme pertinent to the technology.  While lumot has always been …

Improvement of Microalgae Paste Production for Aquaculture Program

Aquafeeds / By

This program has developed an alternative source of larval feed especially when rations of live microalgae are insufficient. Microalgae paste was utilized for two production cycles in order to determine its acceptability and profitability compared with the conventional hatchery protocols. The program also developed proper packaging of the microalgae paste and determined its optimum shelf …

The Watershed Decision Support System (WDSS)

Watershed / By

The Watershed Decision Support System (WDSS) uses modern information and communication technologies to provide support across the three main phases of decision-making: (i) he gathering of “intelligence” for identifying the need for change; (ii) “design” or development of alternative strategies, plans, or options for solving the problem identified during the intelligence-gathering phase, and (iii) the …

National Research and Development Project for Watershed Management: Saug Watershed, Compostela Valley Province and Davao del Norte

Watershed / By

Based on the results of the study the following conclusions were drawn: The biological characteristics of Saug watershed is already degraded considering the low biodiversity for flora, fungi, birds, arthropods and other life within the watershed. The water use efficiency of white lauan was higher compared to ilang-ilang and this indicated better performance of the …

National Research and Development Project for Watershed Management: Quinali A Watershed, Bicol Albay

Watershed / By

The Quinali Watershed’s natural and man-made features, the land cover and corresponding land use, and the climate, particularly precipitation, affect the quality of its water bodies.  The water quality data from fourteen sampling stations within the Quinali Watershed show that elevation influences the water temperature, electrical conductivity and total dissolved solids (TDS). The correlation analysis …

National Research and Development Project for Watershed Management: Pagsanjan-Lumban Watershed, Laguna

Watershed / By

The watershed has a relatively flat to moderately sloping to rolling topography starting from the lakeshore going towards the mountains. In the case of the Pagsanjan-Lumban Watershed, the drainage density value is relatively high, which may be due to the presence of impermeable sub-surface material, sparse vegetation and high relief.  The dominant land cover in …
