Assessment of post-harvest fish losses in two selected lakes of Amhara Region, Northern Ethiopia

open access: yesHeliyon, 2018
Fisheries play a significant role in food security, livelihood, and source of income in developing countries. The annual fish production potential of Ethiopia reaches up to 51, 000 tones, however, the actual production is much less than the potential ...

CRAYFISHERIES IN FINLAND, A SHORT OVERVIEW

open access: yesKnowledge and Management of Aquatic Ecosystems, 2004
Crayfish trapping and activities related to crayfishing have traditionally been lucrative businesses in rural Finland. The catch itself, varying in the 1990’s from 2 to 4 millions crayfish annually, is worth 4 to 8 millions euros.

Reduction in soil organic matter loss caused by water erosion in inter-rows of hop gardens

open access: yesSoil and Water Research, 2019
Currently, when cultivating Humulus lupulus, there is no systematic farming reducing soil erosion in the Czech Republic. As a result, annual irreversible soil and organic matter losses due to intensive rains occur on soils of hop gardens threatened by ...

A device that prevents the loss of catch from a trawl designed to work on a small vessel

open access: yesVestnik of Astrakhan State Technical University. Series: Fishing industry
Improving the technology and design of fishing gear for fishing aquatic biological resources by small vessels is of practical importance in the development of fishing in inland waters and coastal areas with shallow depths, as well as in regions where shallowing of reservoirs is observed.

Reduced Skeletal Muscle Protein Turnover and Thyroid Hormone Metabolism in Adaptive Thermogenesis That Facilitates Body Fat Recovery During Weight Regain

open access: yesFrontiers in Endocrinology, 2019
Objective: The recovery of body composition after weight loss is characterized by an accelerated rate of fat recovery (preferential catch-up fat) resulting partly from an adaptive suppression of thermogenesis.

A Statistical Study of the Variation in Vertical Plankton Hauls, with Special Reference to the Loss of the Catch with Divided Hauls [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1949
The analysis of data on replicate vertical plankton hauls gives a value of the order of 35 % for the coefficient of variation of a single observation for a haul of moderate length. The results are similar to those presented by Winsor & Walford (1936), and Winsor & Clarke (1940); and are not at variance with the suggestion that the animals are ...

Effects of catch crops on silage maize (Zea mays L.): yield, nitrogen uptake efficiency and losses

open access: yesNutrient Cycling in Agroecosystems, 2017
Under the climatic conditions of north-western Europe, silage maize (Zea mays L.) production optimized with respect to nitrogen (N) fertilization and crop rotation is required to reduce N losses. Whether winter catch crops (CC) can serve as a beneficial biological tool in terms of N-loss abatement as well as maize yield also under optimized N ...
