We evaluated a handheld microwave meter (Fish Fat Meter) as an effective tool for the rapid estimation of the total lipid content in the muscle of immature chum salmon (Oncorhynchus keta).
Here we present phenotypic and genetic parameters for the major production and product quality traits in European Whitefish. The studied quality traits were fillet gaping, muscle texture, fillet lipid percentage recorded chemically and by the Fish Fat Meter, fillet protein%, fillet color lightness, and condition factor, and the studied production traits were harvest weight, gutted weight, carcass% of wet weight, fillet% of gutted weight, maturity age, and survival.
Study was to compare energy storage, as indicated by somatic lipids and marine foraging as indicated by stable isotopes of N and C, between seasonal runs of Steelhead of wild and hatchery origin. We did so by sampling Steelhead returning to the Kalama River in southwestern Washington, including summer and winter fish of hatchery and wild origins.
Our study validates the scientific use of routinely collected fat content data from pelagic fish processors.
The accuracy of two indirect methods, the morphometric relative condition index Kn and the bioenergetics index determined with the Fish Fat Meter was investigated by comparing with a direct measure of relative lipid content carried out with a thin layer chromatography flame ionization detector.
The objectives of this study was to study two things. One was to compare the performance of Kn, BIA (bioelectric impedance analysis), and Fish Fat Meter to predict dry mass content as an indicator of energetic status using carp (Cyprinus carpio) and European eel (Anguilla anguilla) as model species..
The other was to test for the effects of temperature on the functionality of BIA (bioelectric impedance analysis) and Fish Fat Meter.
This study reports total lipid in the white muscle of pink and chum salmon by age group from fish caught in high-seas of the North Pacific Ocean and Bering Sea during the spring (April-June) and the summer (June-July) of 2006. In addition, this document reports a preliminary result of muscle lipid analysis using a portable Fish Fat Meter.
In this study, we present the results of experimental two-way mass selection for muscle lipid content in pan-sized rainbow trout. Selection was performed over two generations with the aim of evaluating the efficiency of the Fish Fat Meter values as a non-destructive predictive trait for selection. Direct and correlated responses for some major productive features (growth, body shape and composition, reproductive characteristics) were examined.
Study of Sardine’s somatic condition which is essential in reproductive potential.
The aim of this study is to test the application of the Fish Fat Meter as a surrogate of bomb calorimetry to infer the energy content of both small pelagic fishes. For validation, the Fish Fat Meter values were compared with both energy density (ED; via bomb calorimetry) and Kn values.
