present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

An 18-year database of coral reef fish expatriation poleward in South East Australia was used to estimate persistence of coal reef fish recruits on temperate reefs. Surveys have identified over 150 coral reef fish species recruiting to temperate reefs at latitudes of 34S (Sydney) and 60 species to 37S (Merimbula) with 20 and 5 species respectively overwintering in at least 1 year over the study...

Rainbow trout (Oncorhynchus mykiss) is one of the most-widely cultivated cold fresh water fish in the world. Gamasyab River, with a length of about 200 Km, is one of the longest rivers of Iran. The aim of this research is to determine the effects of trout farm effluents on this river water.  From a total of 24 trout farms in the area,  four farms were randomly selected and three sampling statio...

Increased production of fish through intense culture practices often leads to not only stress and disease problems but also alteration in water quality. The organic wastes and bad water quality influence the growth of pathogenic microorganisms. Bioremediation using pond probiotics is considered a promising way to circumvent these problems. For this study, three earthen fish ponds stocked with P...

Lactobacilli are Gram-positive and catalase negative rods commonly found in lactic acid fermented foods and in the gastrointestinal tract of mammals and birds. Few studies have described lactobacilli in freshwater fish. We analysed the presence of lactobacilli in the intestines of young and adult freshwater fish inhabiting a river environment and from fish reared in an aquaculture unit with a w...

BACKGROUND Antimicrobials are used to directly control bacterial infections in pet (ornamental) fish and are routinely added to the water these fish are shipped in to suppress the growth of potential pathogens during transport. METHODOLOGY/PRINCIPAL FINDINGS To assess the potential effects of this sustained selection pressure, 127 Aeromonas spp. isolated from warm and cold water ornamental fi...

nowadays use of edible films and coatings is increasing due to their biodegradability properties. fish gelatin obtained from fish skin wastage can be used as an appropriate protein compound for preparation of edible films and replacing pork gelatin. in this study, films were prepared from a combination of fish gelatin and three phenolic compounds (caffeic acid, tannic acid and ferulic acid) at ...
