Structural changes in Midwest agriculture over the past two decades have resulted in a number of empty and unused farm buildings. Farmers therefore have been exploring alternative uses of livestock farm buildings for the production of other cash crops, including aquaculture products. In Indiana, Pacific White shrimp (Litopenaeus vannamei) production has attracted interest, and a number of small...

Parasites that invade the nervous system of their hosts have perhaps the best potential to manipulate their host's behavior, but how they manipulate the host, if they do at all, could depend on their position within the host's nervous system. We hypothesize that parasites that live in the nervous system of their host will be randomly distributed if they exert their influence through non-specifi...

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 ...

Here, we report the draft genome sequence of an isolate of Vibrio parahaemolyticus, VP14, recovered from the gut of Penaeus vannamei shrimp farmed in southern India. The genome of VP14 comprised 5,224,046 bp with a GC content of 45.3% and contained 5,326 genes, including 4,972 coding sequences.

Protein food modulates the activity of proteases of the midgut gland of Penaeus vannamei. Shrimp fed with food containing 15, 30 and 50% protein exhibited differences in trypsin and chymotrypsin activity and trypsin mRNA levels. Shrimp fed with 30% protein showed higher trypsin and chymotrypsin activities than those fed 15 or 50% protein. An additional paralogue trypsin was observed with electr...

A preliminary study to characterize filamentous bacteria, whose presence is related to high mortality of Litopenaeus vannamei larvae cultured in Santa Catarina State, Brazil, is reported. The extract of infected larvae was diluted in different concentrations, cultured in marine agar (Difco, Marine Agar 2216) and incubated at 30 degrees C for 48 hours. The biochemical characterization included h...
