Fish meal (FM) has long been considered an essential ingredient for the formulation of shrimp feeds. Until recently, 12%FM was considered a minimum amount, below which weight gain would become reduced due to a reduction in feed intake. In order to test this perceived minimum value, an experiment was conducted on a long-term basis with 4 replicates. Four practical isonitrogenous and isoenergetic...

The feasibility of totally replacing the fishmeal component of marine shrimp (Litopenaeus vannamei) diets was examined both in the laboratory setting and during a full–scale commercial trial. Animals were fed either a traditional fishmeal–based diet or one in which complete replacement of fishmeal, on a per protein basis, was manufactured using a yeast–based product, NuPro®. Laboratory studies ...

—Throughout its native range, American shad Alosa sapidissima is thought to cease feeding during anadromous migration. We examined the feeding habits of American shad during spawning migration by documenting changes in diet composition and feeding that occur in mature fish in the York River, Virginia. American shad were collected prior to and after spawning at various locations on a gradient fr...

The study carried out a 15-day feeding trial of the fleshy shrimp broodstock that have just finished their first spawn using five different maturation feed types (three manufactured feed, fresh and commercial feed) to induce multiple spawning in then analyzed compared hemolymph levels total protein, lipid, hemocyanin, glucose, cholesterol as well ovary histology between treatments identify pote...

Closely related species often specialize on different types of prey, but little is known about the fitness consequences of making an evolutionary transition to a novel diet. Spadefoot toad larvae provide a unique opportunity to reconstruct these evolutionary events. Although most anuran larvae feed on detritus or plankton, Spea larvae have also evolved the ability to consume large anostracan fa...

Feed management in shrimp culture aims to improve the quality of organisms. The application feeding regime has been developed determine best formulation diet order maximize growth rate and survival by increasing feed efficiency minimizing waste. is closely related understanding physiological morphological aspects from larval stage adult stage. success with will be a solution problem high costs ...

Feed is a very important factor in vannamei shrimp culture. The initial stage of stocking the cultivation requiring higher percentage feed. application probiotics intensive culture known to have significant effect on survival shrimp. Encapsulation can increase viability probiotic bacteria compared free cells without encapsulation. Research has been carried out provision encapsulated consortia p...

Shrimp aquaculture, as well as other industries, constantly requires new techniques in order to increase production yield. Modern technologies and other sciences such as biotechnology and microbiology are important tools that could lead to a higher quality and greater quantity of products. Feeding and new practices in farming usually play an important role in aquaculture, and the addition of va...

The use of probiotic bacteria for controlling black disease in fairy shrimp, Branchinella thailandensis, was studied. The bacterial antagonistic activities were tested with Aeromonas hydrophila WS1 which is pathogenic to fairy shrimp. The crossstreak method showed that after 48 hours, Bacillus W120 was the strongest inhibitor of A. hydrophila WS1. Bacillus W120 was characterized and confirmed a...

Commercial shrimp culture has become to the mainstay of the coastal economy of India. The present study was undertaken among 120 shrimp farmers from the two predominant shrimp farming districts of the country. The aim of the study was to find out the various stages of diffusion of scientific shrimp farming through various stages of the adoption from 1997-2003, as well as to study the present ad...
