Sea urchins produce high‐energy, membrane‐bound fecal pellets that contain residual nutrients and large quantities of microbiota. These egesta are readily consumed by the shrimp, Litopenaeus vannamei. Egesta of the sea urchin, Lytechinus variegatus, were evaluated as a feed supplement or total replacement for a commercial shrimp diet. Shrimp were s...
Article
Fish starvation is defined as food deprivation for a long period of time, such that physiological processes become confined to basal metabolism. Starvation provides insights in physiological processes without interference from unknown factors in digestion and nutrient absorption occurring in fed state. Juveniles of amberjack Seriola lalandi were is...
Article
Larval Gulf Killifish Fundulus grandis hatching from air-incubated eggs are precocial, with well-developed mouths and eyes providing an immediate capacity for exogenous feeding. Live feeds are almost universally used in finfish and crustacean hatcheries, with newly hatched brine shrimp Artemia spp. nauplii being a standard. Across two experiments f...
