the effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. there was no significant difference in final weight (m...
The global aquaculture of penaeid shrimp has grown rapidly during the past two decades. In 1998, world shrimp farmers produced an estimated 737 200 t of whole shrimp (this includes 530 200 t from the eastern hemisphere and 207 000t from the western hemisphere), a record 12% increase from the 660 200 t produced in 1997 (Rosenberry 1998, 1999). The shrimp farming sector suffered a serious setback...
the aim of this study was to evaluate the effects of enrichment of artemia with sea weed extract (padina sp.) on the survival and growth rates of post larvae of western white shrimp (litopenaeus vannamei). this investigation was conducted in the shrimp research center, bushehr, iran. the experimental design was done in three dietary treatments with three replications which were conducted in 9 w...
White-spot syndrome virus (WSSV) is a devastating, infectious virus affecting shrimp. Although sensitive techniques involving PCR have been developed to assist farmers in screening shrimp (brood stock) for WSSV prior to stocking ponds, such practices have not yet been applied in Korea. Despite the rationality of implementing screening, there has been some doubt as to whether the stocking of WSS...
In this study, “Tak Cell” probiotic, based on eight-year studies (2009- 2016) of the Iranian Fisheries Sciences Research Institute in National Shrimp Research Institute, and produced in collaboration with the “Tak Zhen Zist ®” company, was added to the diet of western white shrimp (Litopenaeus vannamei) weighing more than 6 grams (in three Different quantities 106, 107 and 108 CFU/Kg) and h...

This study examined the effects of a commercial Lactobacillus probiotic on growth, survival and resistance of western white shrimp (Litopenaeus vannamei) larvae against salinity and formalin stresses in Persian gulf and Oman sea ecology research center. In this experiment, larvae were fed on 6 times a day from mysis I (M1) step to post larvae 5 over 3 treatments with 3 repetitions including a c...

Background & Objectives: White spot, as one of the infectious viral diseases, has made severe losses in shrimp ponds all over the world. Despite extensive efforts made to deal with and control the disease, white spot continues to be a major health problem in shrimp farms across Iran. In this work, the significance of the risk factors of white spot disease epidemic occurred in shrimp ponds o...
the present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of indian white shrimp post-larvae. four hundred and fifty indian white shrimp post-larvae (pl1) were stocked in nine tanks. the tanks were assigned into three treatments: feeding with inulin-treated (110 mg l-1) artemia nauplii (i-t), feeding with inulin-enri...
