Temperature characteristics of peptidase in chironomid larvae, potential fish prey, at various pH values

Allergy to chironomid larvae (red migde larvae) in non professional handlers of fish food.

UNLABELLED Chironomids are insects which inhabit wetlands. In countries such as Sudan, The United States. Egypt and Japan they are the cause of serious environmental allergy. In Europe, and particularly in Spain, allergy to Chironomids is infrequent and has only been described in patients who handle Chironomid larvae which form part of certain fish foods.

Cytotaxonomy and Morphology of Chironomid Larvae (Diptera, Chironomidae) in Armenia

In the study of chironomids in Armenia several species of Orthocladiinae subfamily of Cricotopus genus, Diamesinae subfamily of Diamesa genus, and Chironominae subfamily of Chironomus genus, have been identified. In the Cricotopus genus two sibling species were found, not distinguishable by larval morphological features, but clearly distinct cytogenetically. Keywords—Armenia, Chironomidae, kary...

Live 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...
