Isolation And Characterization Of Microalgae Strains For Live Food In Sulawesi, Indonesia, Wa Iba, Michael Rice May 2015

Isolation And Characterization Of Microalgae Strains For Live Food In Sulawesi, Indonesia, Wa Iba, Michael Rice

Michael A Rice

Four strains of diatoms were isolated from the waters of Kendari Bay in Southeast Sulawesi, Indonesia, including strains of Melosira moniliformis, Chaetoceros, sp. and a larger species that is likely to be Tetraselmis weissflogii. Isolated strains have exhibited a wide range of salinity tolerances in the 20 to 35 psu range. Strains of isolated phytoplankton were able to reach high densities consistent with strains suitable for use as aquaculture feeds. One strain Kbl-3 attained lipid content of 22.3 percent per gram dry weight at salinity of 35 psu, suggesting that it may be a good feed for shrimp larvae. Most …

Microalgae In Eastern Pacific White Shrimp Hatcheries: A Review On Roles And Culture Environments, Wa Iba, Michael A. Rice, Gary H. Wikfors Aug 2014

Microalgae In Eastern Pacific White Shrimp Hatcheries: A Review On Roles And Culture Environments, Wa Iba, Michael A. Rice, Gary H. Wikfors

Michael A Rice

Demand for shrimp, particularly the eastern Pacific white shrimp Litopenaeus vannamei (Boone 1931), will continue to increase in Asian and worldwide seafood markets. Providing shrimp farms with a robust, healthy, and continuous supply of shrimp seed is a challenge that must be addressed to meet the demand. Shrimp feed during hatchery production still relies on live microalgae, despite many years of effort to find suitable full or partial-replacement diet alternatives. Successful mass production of microalgae for hatchery feed to obtain good quality shrimp seedstock depends on a number of environmental factors that determine the growth and nutritional values of various …

Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice Jun 2014

Extension Programming In Support Of Public Policy For The Management Of Aquaculture In Common Water Bodies, Michael A. Rice

Michael A Rice

Many countries of Asia, including Indonesia, have experienced the problem of hypoxic fish kills among fish in netpens and fish corrals in various publicly-held water bodies. Fish farming in enclosures in public water bodies attractive because of low overhead costs in comparison to farming the identical species in constructed ponds. But aerobic bacterial degradation of feed and fish feces in common waters can lead to oxygen depletion, thus causing fish kills. Mass-balance and ecological carrying capacity models and education through and extension programming can be used to inform policy makers as to the maximum biomass of farmed fish allowable before …

Aquaculture In Dagupan City, Philippines, Michael A. Rice, Arthur Z. Devera Feb 1998

Aquaculture In Dagupan City, Philippines, Michael A. Rice, Arthur Z. Devera

Michael A Rice

The development of aquaculture in the Agno-Pantal-Calmay River Estuary system of Dagupan City, Pangasinan Province in the Philippines is reviewed. Traditionally, extensive pond culture of milkfish, Chanos chanos and penaeid shrimp was practiced along with culture of mangrove oysters, Crassostrea iredalei, in adjacent estuarine waterways. Netpen culture of serranid groupers in the estuaries began in the early 1980s, followed by intensive fish pen culture of milkfish in the late 1980s. Over intensification of finfish aquaculture led to hyper eutrophication and fish kills beginning in 1996. Official governmental response to the fish kills is reported, and recommendations to prevent future fish …
