Salmon Parr

Hatchery-reared Atlantic salmon (Salmo salar) parr were captured 1–3 mo after release in streams, along with wild parr from the same streams. Identification of their stomach contents showed total number of organisms and number of taxa per stomach were greater and there was a higher index of stomach fullness in wild than in hatchery parr resident ≤ 2 mo in a stream. Wild parr consumed more Brachycentridae, Hydroptilidae, Diptera, and Plecoptera than did hatchery parr, but sometimes less Odontoceridae and Heptageniidae. These differences may have arisen from size-dependent food selection, the effects of feeding experience, or possible microhabitat differences between wild and hatchery parr. Key words: salmon parr, hatchery-reared, wild, feeding

Dead Prey

Underyearling rainbow trout (Salmo gairdneri) in experimental stream tanks presented with live and dead prey preferred live prey. Trout fry generally were size selective predators and previous feeding experience did not affect the size of prey consumed. When a wide range of prey sizes was offered, larger trout fry fed upon bigger prey than did smaller fry. Cyclops were underrepresented in trout fry stomachs relative to Daphnia of similar size.

Child Eating

Responsive feeding is an important aspect of child care, yet little is known about child eating and caregiver feeding behavior in Kenya. This study aimed to develop a mealtime observation methodology and assess child eating and caregiver feeding behavior in healthy and undernourished children in Nairobi. Healthy (n = 6) and undernourished (n = 13) children aged 6–24 months were observed during a meal, with standardized rating of child interest in food, mood, distraction and caregiver responsiveness. Eating and feeding behavior varied with the stage of the meal. Child interest in food decreased and child and caregiver distraction increased as the meal progressed. Healthy children were happy and interested in food during meals, but undernourished children often had low interest in food (7/13). The 7 undernourished children eating home food were distracted (3) and unhappy (5) but children eating ready-to-use therapeutic foods (6) were all happy and undistracted. Caregivers of healthy children offered encouragement more often during meals than caregivers of undernourished children (5/6 healthy, 3/13 undernourished). Meal observations were resource intensive and could give only a snapshot of the child feeding experience. More efficient research methods that can capture a general assessment of infant eating behavior are needed.
