To circumvent the limits of muscle, ultrafast movements achieve high power through the use of springs and latches. The time scale of these movements is too short for control through typical neuromuscular mechanisms, thus ultrafast movements are either invariant or controlled prior to movement. We tested whether mantis shrimp (Stomatopoda: Neogonodactylus bredini) vary their ultrafast smashing s...

While free amino acids are routinely used in feeds for terrestrial farm animals, it is – except for few aqua species – not commonly practiced in finfish and shrimp nutrition. Reasons for not using free amino acids are often related to doubts on the efficiency and availability of these ingredients. This paper discusses aspects on the availability and efficiency of supplemental amino acids in fis...

This study aimed to determine the optimum stocking density that supported optimization of water quality and production white shrimp (Litopenaeus vannamei) ponds. was conducted in 2 different cycles, namely cycles 14 15 with densities each cycle, 94 150 shrimp/m2. Each cycle represented by ponds, ponds B5 B6. Experimental animals used were post-larvae stadia 9-10 (PL 9-10) a size 9-12 mm. parame...

Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...

ARTEMIA is commonly known as the brine shrimp. It is a crustacean. It lives high saline waters. It is widely distributed throughout the world; it is the most important live feed organism. ARTEMIA lives in high saline environment where its predators cannot survive. Hence ARTEMIA can be effectively cultured in saline water. Such water bodies are found in solar saltpans, which occur all along Indi...

Shrimp waste contains protein that binds to chitin and is difficult digest by poultry, so it necessary carry out a fermentation process using Bacillus licheniformis, Lactobacillus sp., Saccharomyces cerevisiae. This study was conducted determine the Effect of fermented shrimp products resulted in optimal conversion meat protein, carcass weight, abdominal fat native chickens. The method used com...

The study was taken to analyse the Shrimp Culture Business in Nellore district, Andhra Pradesh. performance of shrimp (Litopenaeus vannamei) culture business terms production, marketing, finance and also constraints faced by farmers analysed. Aquaculture were classified into small (1-2 ha), semi-medium (2-4 medium (4-10 ha) large (>10 ha). results revealed that average gross income earned Rs...

The aim of this study was to assess the ecological factors associated with feeding by Rachycentron canadum (cobia) in the waters of Hormuzgan Province, Iran. Specimens were collected seasonally from Sep. 2014–Sep. 2015 from the Ferdows-1 survey ship and from landing areas in the city of Bandar Abbas. A total of 577 cobia were collected (340 male, 237 female) (20–161 cm Total length). Our result...

Five size groups of hatchery reared cod (2–109 g) and three size groups of wild cod (447–2213 g) were reared at a range of constant temperatures. All groups were fed to satiation, the hatchery fish on dry feed and the wild fish on capelin and shrimp. The optimal temperature for growth decreased linearly with fish weight on a log scale from 17 C for 2 g fish to 7 C for 2000 g fish. Similarly, th...
