Infusoria suitable live food for fish larvae
Infusoria are a group of aquatic organisms that are used to feed fish larvae. They are actually small forms of life in freshwater that include: Amoeba, Oglena, Green algae, Paramecium, Rotifer, Vertisella, and Invertebrates are small. Due to its small size, Infusoria can be used to breed newly hatched larvae of many aquarium fish species such as gourami and beta fish. Many home aquarium owners ...
متن کاملLive foods in the feeding of aquarium fish larvae
At reproduction centers, using live food is important, especially when it comes to the first feeding of aquarium fish larvae. Live foods commonly used in the aquarium aquaculture industry include rotifers in two sizes, small types with a size of 50-110 microns, and larger types with a size of 100-200 microns, Artemia, and copepods. Fish larvae in marine aquariums primarily consume copepod...
متن کاملSimulation and optimization of live fish locomotion in a biomimetic robot fish
This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) and image processing methods and optimal coefficients of the motion equations and appropria...
متن کاملImprovemet of ornamental fish color with live algae feeding
In the nature, ornamental fish have a variety of beautiful colors that becomes pale or dull colored in conditions of intensive culture in breeding halls. Feeding these fish with algae can improve their color. For this purpose, rainbow trout larval stage feed was used as the base feed. The treated foods obtained from the powdering of the basic food were impregnated with different percentages of ...
متن کاملHUANG, BOOM, FISHER: HIERARCHICAL CLASSIFICATION FOR LIVE FISH RECOGNITION1 Hierarchical Classification for Live Fish Recognition
Live fish recognition in the open sea is a challenging multi-class classification task. We propose a hierarchical classification approach to recognize live fish from underwater videos. However, the hierarchical method accumulates misclassified samples into deeper layers and these accumulated errors reduce the average accuracy. We propose a set of heuristics to help construct more accurate hiera...
