Feeding Habits of Common Snook, Centropomus undecimalis, in Charlotte Harbor, Florida

Dietary protein requirement in common snook (Centropomus undecimalis ) juveniles reared in marine and brackish water

“…Protein, being one of the most expensive and important nutrients in the formulation of sh diets, needs to be properly determined in the feed to improve growth, reduce ammonia excretion and decrease production costs (Xia et al 2015). According to Concha-Frías et al (2016), digestion of proteins starts in the stomach, which has an acidic environment, through the action of pepsin and continues in the intestine in an alkaline environment where greater trypsin activity is observed (Blewett et al 2006). This implies a very high protein requirement for saline environments, so it is essential that the diet formulation include high-protein ingredients.…”

“…The color and texture of its meat make it a promising candidate for aquaculture (Álvarez-Lajonchére 2001). It is a carnivorous sh, which during its juvenile stage feeds on other sh and crustaceans, which suggests it has a high demand for protein (Blewett et al 2006). Many sh species have high growth associated with their dietary protein intake, with a maximum requirement that provides them with adequate amino acid content to maximize their growth (Liu et al 2013, Xia et al 2015), which is determined by di erent models, the most common being broken-line regression analysis (Robbins et al 2006).…”

Resource Partitioning Among Three Mesoconsumers at a Marsh Mangrove Ecotone: a Response to a Seasonal Resource Pulse Subsidy

“…Numerical counts were converted into proportional contributions to each individual's diet during any one season. Consumed fishes that were not readily identifiable passed the level of 'unknown fish' were excluded from analyses (accounting for 30% of diet items), which is comparable to previous diet studies conducted on piscivorous fishes (Jepsen et al 1997;Blewett et al 2006;Adams et al 2009). I calculated two dietary metrics of interest: proportion of full stomachs per bout and numerical proportions of cyprinodontoids, invertebrates, and sunfishes found in diet samples.…”

“…Snook are a tropical euryhaline ambush piscivore found throughout the Caribbean in habitats ranging from land-locked freshwater lakes to offshore reefs (Blewett et al 2006;Muller and Taylor 2006;Adams et al 2011). Largemouth bass and bowfin are mesopredators found throughout Everglades freshwater marshes, including natural (Chick et al 2004;Trexler et al 2005) and man-made habitats (e.g., canals; Rehage and Trexler 2006).…”

Investigating Sub-tropical Community Resistance and Resilience to Climate Disturbance

“…I measured the caloric content of prey items that made up greater than 1% of the biomass that snook consume, or are common prey items consumed by snook in other systems (Blewett et al 2006;Stevens et al 2010;). I measured the caloric content of focal prey using bomb calorimetry (Kushlan 1979;Adams et al 1982).…”
