Developing bioelectrical impedance analysis methods for age0 brook trout
Year class strength of many fishes often is determined by survival through the first winter. Increased fat reserves improve survival and overall cohort success. Bioelectrical impedance analysis (BIA) methods are established for estimating proximate composition of adult brook trout, Salvelinus fontinalis (Mitchill), but none have been developed for early life stages. Small-fish BIA would provide...
متن کاملDevelopment of temperature correction equations for bioelectrical impedance analysis models for brook trout Salvelinus fontinalis.
The objective of this study was to establish the relationships between bioelectrical impedance analysis (BIA) measures (resistance and reactance) and temperature and to determine if corrections improve BIA models for brook trout Salvelinus fontinalis when used over a wide range of temperatures. Both resistance and reactance significantly decreased as temperature increased. Application of temper...
متن کاملInfluence of Electrode Type and Location upon Bioelectrical Impedance Analysis Measurements of Brook Trout
In recent years, bioelectrical impedance analysis (BIA) has started to develop into a low-cost tool that can provide accurate estimates of fish condition. Past researchers have had success predicting mass-based proximate condition components, but attempts to predict percent-based components have not been as successful, suggesting that methodological improvements are needed. The percent dry weig...
متن کاملBioelectrical impedance analysis revisited.
Although total limb volume measurements are used to track the progress of lymphedema and its treatment, these measurements can be confounded by changes other than fluid excess namely muscle or fat gain. Bioelectrical impedance analysis (BIA) is a technique that specifically quantifies both total body fluid and extracellular fluid in extremities. Whereas BIA has potential as a quick, inexpensive...
متن کاملEmpirical relationships between body tissue composition and bioelectrical impedance of brook trout Salvelinus fontinalis from a Rocky Mountain Stream.
Bioelectrical impedance analysis (BIA) analysis was carried out in the field on anaesthetized Salvelinus fontinalis electrofished from a mountain stream in Alberta, Canada; the fish were then sacrificed for subsequent analysis of tissue composition. Water content was assessed by comparing wet and dry mass, and total body lipid content was measured by Soxhlet extraction with petroleum ether. A m...
