IntroductionAquaculture has become a vital component of global food production, contributing significantly to food security, nutritional requirements, and economic development [4]. In India, aquaculture plays a crucial role in the rural economy, with Indian major carps, particularly Rohu (Labeo rohita) and Catla (Catla catla), being predominant species in freshwater fish culture. Efficient feed ma ...

IntroductionIndian giant carps (IMCs), along with fish species such as Catla catla, Labeo rohita and Cirrhinus mrigala, are economically important freshwater fish species widely cultivated in the Indian subcontinent They are highly valued for their meat quality, fast growth rate, and adaptability to various environmental conditions. The cultivation of IMCs plays a crucial role in the aquaculture s ...

IntroductionFish or any animal needs an adequate balanced diet that contains all the required necessary essential nutrients to have optimal growth. These nutrient requirements vary from species to species, sex, age, the environment where it lives, different stages of larval development, and the health status of the species. A minimum of 35 to 45 nutrients is required for marine fish. To have the b ...

INTRODUCTIONDiatoms play a major component and dominant life form of the phytoplankton community. Diatoms are made up of complex silica cell wall and microscopically single-celled autotrophic eukaryotic algae belonging to the class Bacillariophyceae and kingdom Protista1. The tiny algae diatom range from 2 and 500µm in length or diameter and their habitation vary from ocean to freshwater sys ...

INTRODUCTIONThe macroscopic algae has always been associated with human and animal life for their innumerable beneficial properties and has been used as a source of food, feed, fertilizer, medicine and the availability of economically cheap phytochemicals.[1,2] Seaweeds are also used as raw material for many industrial products like agar, alginates and carrageenan.[3,4,5] Fresh and dry seaweeds es ...

I. INTRODUCTIONVibrios have emerged as a major problem affecting shrimp culture across the world. The Outbreaks and mass mortalities of vibrios in hatcheries and grow out ponds of shrimp have been reported across many regions (Couch 1978; Overstreet 1978; Lightner 1983, 1985, 1988, 1996; Sindermann 1990; Ruangpan and Kitao 1991, 1992; Chen et al. 1992; Yang et al. 1992; de la Pena et al. 1993; Jir ...

INTRODUCTION:Leptospirosis, a zoonotic disease caused by the spirochetal bacteria Leptospira is a common disease of livestock, pet animals with its prevalence worldwide 1. The geographical distribution of leptospirosis has been overlapping over the decades and produce endemic and epidemic acute febrile diseases 2. Sporadic outbreaks have been reported from the countries like USA, UK, Australia, Ne ...

IntroductionSilver has been known for antibacterial activity since ancient times. The importance of silver has regained due to the increase of bacterial resistance to antibiotics, caused by their overuse. Silver nano particles and silver based compounds containing ionic silver (Ag+) or metallic silver (Ag0) which possess antimicrobial activity are of great importance in the field of medicine. Silv ...

IntroductionSilver has long been known to exhibit a strong toxic activity towards a wide range of microorganisms, for this reason silver based compounds have been extensively used in many bactericidal applications. Nano particles due to their large surface area are highly reactive and Ag Nano particles have been tested in various fields of biological sciences, Viz drug delivery, wound treatment, b ...

INTRODUCTIONAlgae are simple photosynthetic eukaryotes which owing to their colonization of the oceans are responsible for up to 50% of the planet’s atmospheric carbon fixation (1), secondary and primary metabolites produced by these algae may be good potential bioactive compounds of interest in pharmaceutical industry (2). Many bioactive and pharmacologically active substances have been iso ...
