A comparison of macronutrient levels in green mussel (Perna viridis) and brown mussel (Modiolus metcalfei Hanley) T Rochanaburanon -
Journal of the Science Society of Thailand, 1980 - The Science Society of ThailandTwo species of mussel from Panay Island, Philippines, have been analyzed for moisture, crude protein, crude fat, ash, carbohydrated, crude fibre and minerals (calcium and phosphrus). Results showed that the brown mussel (Modiolus metcalfei), both the marketable size and the small ones, have higher protein content (71.49 and 67.10% dry weight) than the marketable-size green mussel (Perna viridis ), 63.94%. The green mussel contained more fat but less ash, crude fibre and minerals than the brown mussel.
Polyculture of green mussels, brown mussels and oysters with shrimp control luminous bacterial disease in a simulated culture system EA Tendencia -
Aquaculture, 2007 - ElsevierShrimp mortality due to luminous bacteria has been a problem of the shrimp industry worldwide. Polyculture of shrimp with finfish, such as grouper, seabass, snapper, siganid, Tilapia hornorum, and the Genetically Improved Farmed Tilapia (GIFT), could control the growth of luminous bacteria. One way to reduce adverse environmental impact and to reduce bacterial count is through the use of bivalves to filter pond effluents. This study investigated the effect of several bivalves on the growth of luminous bacteria in a simulated shrimp culture environment using concrete tanks. Tanks were stocked with shrimp at a biomass of 100 g/m3 and with brown mussel (158 pcs/m3), green mussel (137 pcs/m3), or oyster (376 pcs/m3). Growth of luminous bacteria decreased to below 101 cfu/ml in tanks with green mussel after 5 d, brown mussel after 16 d, and oyster after 17 d. Bivalves, such as green and brown mussels, and oyster, could be used as an alternative species for polyculture with shrimp to control disease due to luminous bacteria.
Apparent digestibility coefficient of nutrients from shrimp, mussel, diatom and seaweed by juvenile Holothuria scabra Jaeger The ability of Holothuria scabra to digest nutrients, such as organic matter (OM), protein and carbohydrate from animal and plant feed ingredients was investigated. Four test feeds prepared by mixing sand with single ingredients from animal sources (shrimp and mussel) and plant sources (diatom and seaweed) were fed to H. scabra to estimate apparent digestibility coefficient (ADC). The total assimilated nutrient (TAN) increased with ADC, whereas ingestion rate (IR) varied slightly among the feeds suggesting that ADC might be a good indicator of nutrient availability to H. scabra. The ADCOM of shrimp and mussel was significantly higher than that diatom and seaweed: 86.2%, 77.1%, 55.1% and 32.3% respectively. ADCprotein was similar for shrimp (88.7%), mussel (84.8%) and diatom (75.2%), but significantly lower in seaweed (34.4%). ADCcarbohydrate was similar in mussel (58.5%) and diatom (58.3%) as well as in seaweed (31.6) and shrimp (28.0%). ADCprotein was relatively higher than ADCcarbohydrate suggesting that H. scabra generally digests more protein than carbohydrate. Furthermore, results indicated that nutrients from animal-based feeds are more efficiently digested by H. scabra; thus, animal ingredients rich in easily digestible protein could potentially provide an efficiently balanced diet for H. scabra fed with diatom containing high easily digestible carbohydrate.
