Penaeus vannamei shrimp farming in Indonesia is faced with several challenges in the environmental, economic, and social aspects. Therefore, this study aims to assess the benefits of novel nanobubble aeration systems for the ecosystem, businesses, and communities. This is an experimental study conducted by comparing P. vannamei post larva 10 reared at a density of 2000 inds./L in a pond treated with nanobubble and without treatments (control). Furthermore, the Net Present Value (NPV) and payback period were calculated to assess the economic feasibility of nanobubble, while community interviews were used for the social sectors. Based on the results, environmental wastes of shrimp farming in form of total ammonia nitrogen (TAN) were reduced by 9% from 2.58 mg/l (95%CI: 0,91, 4,25) in control compared to 2.35 mg/l (95%CI: 0,86, 3,84) in treatment. Furthermore, the revenues from post larva sales for five years and nanobubble investment costs showed that the estimated NPV was IDR 64,824,374 with a payback period of 1.7 years. The interviews on traditional shrimp farming showed that 61.1% to 72.2% of community members agreed on the use of nanobubble aeration to support livelihoods. Therefore, the use of nanobubbles is feasible to support sustainable P. vannamei farming.

A new emerging disease called “translucent post-larvae disease” (TPD) or “glass post-larvae disease” (GPD) of Penaeus vannamei, characterized by pale or colorless hepatopancreas and digestive tract, has become an urgent threat to the shrimp farming industry. Following this clue that treatment of an antibacterial agent could alleviate the disease, systematic investigation of the potential infectious agent of TPD was conducted using bacterial identification and artificial challenge tests to fulfill Koch’s postulates. A dominant bacterial isolate, Vp-JS20200428004-2, from the moribund individuals was isolated and identified as Vibrio parahaemolyticus based on multi-locus sequence analysis. However, Vp-JS20200428004-2 differed from the V. parahaemolyticus that caused typical acute hepatopancreatic necrosis disease. Immersion challenge tests revealed that Vp-JS20200428004-2 could cause 100% mortality within 40 h at a dose of 1.83 × 106 CFU/mL, and experimental infected shrimp showed similar clinical signs of TPD. The Vp-JS20200428004-2 could be re-isolated and identified from the experimental infected individuals. Moreover, histopathological analysis of diseased samples indicated that Vp-JS20200428004-2 caused severe necrosis and sloughing of epithelial cells of the hepatopancreas and midgut in shrimp individuals both naturally and experimentally infected. Our present results indicated that Vp-JS20200428004-2 is a highly virulent infectious agent associated with the TPD and deserves further attention.

In any aquaculture business, sustainability of a system improved profits. At present although biosecurity and BAqP are in place, more needed to be done. With emerging disease challenges innovated designs and operation systems are developing for sustainable production. One of the most important factors the investors, shrimp farmers and technicians need to be aware of is that whatever waste discharged into environment will come back to you in a form of disease sooner or later. Before mid1990s major threats to shrimp farming was mainly bacterial diseases. In Asia from late 1994 appearance of viral diseases such as white spot syndrome virus (WSSV) and a few others like yellow head virus (YHV), infectious myonecrosis virus (IMNV). In 2001 with availability of Specific Pathogen Free (SPF) Penaeus vannamei broodstock from Hawaii, the shrimp farming industry took off much faster.

The introduction of Penaeus vannamei Boone, 1931, during 2009 opened up a new vista in Indian aquaculture. Presently, 90% of shrimp farming in the country is contributed by P. vannamei. The potential productivity level is around 10-12 t ha-1 and handling the feed during the course of culture increases considerably especially towards the end of culture period. This calls for automation in shrimp farming especially for feeding practices so that labour problem faced by the industry could be solved. The biosecurity requirement for vannamei farming can also be best met with the use of automatic feeders. The present study attempted designing and development of an indigenous automatic feeder for P. vannamei culture. The feeder design comprised four major components viz., feed hopper, distribution mechanism, a control unit for regulating the quantity and frequency of feeding and the power supply unit. Automation is effected through two timers with a digital display so that dispensing of the feed as well as duration of feeding could be easily adjusted by the farmers. Performance evaluation of the automatic feeder was done exhaustively and the results clearly showed that the maximum dispersion distance was 39 m dia and the maximum quantity of feed dispersed was 620 g in 5 sec. On farm evaluation of the feeder was also carried out in a shrimp pond and the installation height was optimised as approximately 75 cm - 1 m from the water level for facilitating better dispersion of the feed.

Production of white leg shrimp (Penaeus vannamei) is a very important economic activity in the overall farming system in China. In spite of the present successes witnessed by white leg shrimp farming, there are many challenges (disease, overfeeding, effluent discharge, lack of technical knowledge, low educational level, inexperienced managers, the high cost of production among others) continuing to set back the growth of this sector in China. The study was conducted in Jiangsu province because is one of the leading producing provinces of White-leg shrimp (Penaeus vannamei) in China. The research examines the technical efficiency level of white leg shrimp production in Jiangsu Province, China. Three seasonal crops data in 2016 crop year were collected from 52 white leg shrimp farmers in the study area. All data were coded in Excel 2007 spreadsheet package and analysed with SPSS version 20 and DEAP version 2.1 software at 95% confidence level. Descriptive statistical, regression and Data Envelopment Analyses (DEA) were used to analyse the data. Results revealed an average technical efficiency score of 83.1%, under a constant return to scale. Majority of the farmers (62%) were technically inefficient in utilising input resources with technical efficiency score less than 1. Twenty farmers were technically efficient with technical efficiency (TE) score equal to 1. Feed, fingerlings and chemical showed significant negative influence on technical efficiency at 5% level of significance while labor, fixed cost and age exhibited strong negative impact at 1% level of significance.

Background: Nursery rearing of Penaeus vannamei became inevitable in the Indian shrimp farming industry, since intensification of culture practices in grow-out systems caused nitrogenous wastes accumulation, diseases, mortality and premature harvests resulted in high food conversion ratio, lower production and profits. The nursery rearing in traditional water exchange systems often getting failure because of nitrogenous waste accumulation. Hence, the present experiment was planned to rear P. vannamei in bioflocs systems (BFS) with different salinities and carbon sources. Methods: The experiment was conducted in 0.22 m3 tanks with three different salinity groups viz., 35 ppt, 20 ppt and 5 ppt and in each salinity sugar, molasses used as carbon sources to maintain an estimated C/N ratio of 15:1 and controls without carbon sources. Experimental tanks were stocked @6 post larvae/l, with pre-salinity acclimatized P.vannamei seeds having 0.0029±0.0003g size and nursed for a period of 5 weeks. Result: The nitrogenous waste accumulation was reduced significantly (p less than 0.05), also average body weight and survival rate of the seeds showed significant difference (p less than 0.001) between treatments and controls and within treatments (p less than 0.05). Salinity, carbon sources and their interaction influenced the growth characteristics significantly (p less than 0.01). The present experiment manifested promising results of bioflocs nurseries in rearing of P. vannamei seeds at different salinities.
