ON FEEDING MECHANISMS AND CLEARANCE RATES OF MOLLUSCAN VELIGERS [PDF]

open access: yesThe Biological Bulletin, 1979
1. Beat of preoral cilia and particle paths were filmed for veligers of Crassostrea gigas, Tritonia diomedea, Nassarius obsoletus and an unidentified prosobranch. Particle captures were filmed for the three identified species. 2. Clearance rates per unit length of velar edge are estimated from the equation (L2-R2)WPF/2C, where L is cilium length, R a ...

Feed Rate of a Rotary Feeder

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1978
The revolution characteristic of feed rate of a rotary feeder is examined theoretically and experimentally when back pressure is not applied to the feeder outlet. The revolution giving the maximum feed rate is dependent on the inlet dimension, the total volume of wheel rooms and the number of wheel rooms of the feeder and on the relaxation time of ...

Feeding Behaviour, Swimming Activity and Boldness Explain Variation in Feed Intake and Growth of Sole (Solea Solea) Reared in Captivity [PDF]

open access: yes, 2011
The major economic constraint for culturing sole (Solea solea) is its slow and variable growth. The objective was to study the relationship between feed intake/efficiency, growth, and (non-) feeding behaviour of sole.

Substitution of natural feed with artificial feed on the survival rate and growth rate of giant-snakehead Channa micropeltes

open access: yesJurnal Akuakultur Indonesia, 2021
The purpose of this study was to determine the best percentage of artificial feed substitution for growth and survival rate of giant-snakehead. This study used a completely randomized design (CRD) with 4 levels of artificial feed substitution dose treatment, namely 25%, 50%, 75%, 100%, and control (without artificial substitution). The feed used in the
