Six sampling places across the hatchery system were selected for monitoring over a 10-month period and analyzed with Atomic Absorption Spectrometry (AAS). Results showed that the heavy metal AbentinEstimhttp://www.blogger.com/profile/14898038345046811515noreply@blogger.com6tag:blogger.com,1999:blog-8359840392303623972.post-1941790736834231802009-02-25T09:11:00.003+08:002009-02-25T09:28:24.658+08:00Water quality remediation in a fish hatchery using biological and mechanical filtersWater quality is a major factor in fish hatchery operations and management. Deterioration in the quality of water increases stress on the captive animals, reduces their growth, makes them vulnerable to disease and can cause heavy mortality. Managing water quality is important but expensive. In this study, an innovative method was developed to collectively use coral rubble, aquamats, synthetic AbentinEstimhttp://www.blogger.com/profile/14898038345046811515noreply@blogger.com0tag:blogger.com,1999:blog-8359840392303623972.post-56944277839960056762009-02-13T09:44:00.001+08:002009-02-13T10:02:05.975+08:00Tidal effects on the seawater quality of a fish hatchery water intakeThe seawater temperature, DO, pH, salinity, conductivity, total dissolved solids, total alkalinity, total carbon dioxide, turbidity, total suspended solids, NH3-N, NO2-N, NO3-N, PO4-P, Cd, Cr, Cu, Fe and Pb concentrations in a fish hatchery were determined.

Seawater of sub-optimum quality is known to affect spawning and cause high larval mortality. This study was undertaken to assess the water quality in the hatchery at Universiti Malaysia Sabah. Attention was given to parameters including temperature, DO, pH and salinity. Samplings were done at six stations from March to December 2006AbentinEstimhttp://www.blogger.com/profile/14898038345046811515noreply@blogger.com0
