Influence of size and density on filtration rate modeling and nutrient uptake by green mussel (Perna viridis)

Size-dependent changes in toxicity of Perna viridis mussels exposed to natural populations of Pyrodinium bahamense var. compressum

“…In contrast, at low cell density, the filtration rate seems to be following that observed by Tantanasarit et al (Tantanasarit, Babel, Englande, & Meksumpun, 2013) based on the measured specific toxicity of the mussels at low cell density ( Figure 5). In our results, the specific toxicity tends to decrease with length though the data showed a higher scatter (R 2 = 0.548).…”

Uptake, release, and absorption of nutrients into the marine environment by the green mussel (Perna viridis)

“…In agreement with other researches (Qian et al, 2001;Masilamoni et al, 2001;Gao et al, 2008), excretion by mussels increases with increasing shell length. By integrating the green mussel filtration kinetics model (Tantanasarit et al, 2013a) with the faeces release rate found in this study (Fig. 1), it is clearly evident that the amount of faeces production is related to mussel size.…”

“…The consumption of food was determined by the difference between initial and final concentration of C. calcitrans cells in the reactor measured as chlorophyll a. An individual C. calcitrans cell contains chlorophyll a 0.8 pg (Tantanasarit et al, 2013a). The faecal material was collected by gentle suction.…”

“…In order to develop the correlation between the releases rate of nutrients by the green mussel, N r (mg/h/indv), and green mussel size (g DW tissue), the green mussel filtration kinetics model (Tantanasarit et al, 2013a) was employed in the form of the following equation.…”

“…Green mussel size was converted to g DW tissue by using the equation below (Tantanasarit et al, 2013a).…”
