“…However, the growth of shrimp is often not synchronized; some grow fast, whereas some grow slow, which affects the economic benefits of farmers. It has been reported that the growth performance of aquatic animals is related to genetics (Tan et al, 2019), environmental factors (Duy et al., 2012), disease (Sellars et al., 2019), stocking density (Façanha, Oliveira‐Neto, Figueiredo‐Silva, & Nunes, 2016) and food (Sookying, Silva, Davis, & Hanson, 2011). Till now, the main mechanism that affects the asynchronous growth of shrimp is still unclear.…”

Penaeus monodon provides a high‐quality protein source for humanity, and pond cultured shrimp often presents asynchronous growth. Microbial communities are important for the digestion and immunity of shrimp. Therefore, in this study, we investigated the bacterial characteristics of the intestine and rearing water of asynchronously growing P. monodon that were cultured in outdoor and indoor pond respectively. The results showed that the bacterial community of the rearing water was more complex than that of the intestine; the fast‐growing shrimp in the indoor pond had higher intestinal bacterial diversity. Besides, the dominant bacterial composition of the water was more complex than that of the intestinal. Specifically, the abundance of Proteobacteria in the intestine was consistent with the growth performance of shrimp in the outdoor pond, which was exactly the opposite in the indoor pond. At the genus level, two cyanobacteria, Limnothrix and Cyanobium PCC‐6307, were dominant in the indoor and outdoor water respectively. In the outdoor pond, Bacillus was dominant in the slow‐growing shrimp intestines, while Vibrio was dominant in the fast‐growing shrimp. The intestinal microbes of the fast‐growing shrimp had higher proteasome metabolic capacity. These results can provide new insights into microbiome characteristics involved in the asynchronous growth of shrimp.

“…Recent publications by Sellars et al [56] are worth noting. According to these authors, IHHNV infection has been typically observed to be relatively benign in aquaculture production of the black tiger shrimp (P. monodon).…”

“…With yield losses estimated to be worth AU$67,000 gross for a 1-ha commercial pond. Sellars et al [56] suggest that in cases where IHHNV is highly prevalent in wild broodstock it is fundamental to quantify the infection severity by quantitative polymerase chain reaction (qPCR), such testing should be used as a means of identifying and removing these high-load broodstock before they are conditioned and spawned. This will ensure that only IHHNV-free or IHHNV-low seedstock are used for production.…”

“…The study focused on IHHNV, a commercially relevant small ssDNA virus also described as Penaeus stylirostris densovirus (PstDNV) classified as type species of the Penstyldensovirus genus in the Densovirinae sub-family of the Parvoviridae (Saksmerprome et al, 2010;Rai et al, 2011;Tang and Lightner, 2002;Shike et al, 2000;King et al, 2012;Cotmore et al, 2014). The study used PASF beds having opportunistic access to wastewater from ponds used in a trial to determine the impact of high-load IHHNV infection on P. monodon growth performance and survival (Sellars et al, 2019). The qPCR data were used to investigate P. helleri as an IHHNV carrier, and remedial measures that could be used in commercial settings (e.g.…”

Polychaetes (Perinereis helleri) reared in sand beds filtering nutrients from shrimp (Penaeus monodon) culture ponds can transiently carry IHHNV

A polychaete-assisted sand filter (PASF) system has been developed to help remove nutrients from aquaculture pond wastewater whilst also producing polychaetes that are highly prized as bait by recreational anglers and as a dietary supplement to improve the fecundity of shrimp broodstock. Whilst rearing polychaetes in PASF beds offers potential to reduce impacts of sourcing them from the wild, the use of wastewater from ponds rearing shrimp such as Penaeus monodon will present a biosecurity risk of viruses being transferred to, and potentially amplified in, the worms. To assess such risks for transmitting infectious hypodermal and haematopoietic necrosis virus (IHHNV), groups of 3 or 4 PASF beds seeded with sand worm (Perinereis helleri) juveniles were supplied with wastewater from ponds of P. monodon with either high-load or low-load IHHNV infections. TaqMan realtime qPCR identified low loads of IHHNV (≤878 IHHNV DNA copies 200 ng −1 TNA) in most worms from PASF beds supplied wastewater from the high-load pond. IHHNV was either not detected or detected at the qPCR test sensitivity limits in worms from beds supplied wastewater from the low-load pond. Purging harvested worms of their gut contents in clean filtered seawater for 2 days significantly reduced IHHNV loads. Reverting PASF beds to clean seawater for 8 weeks before harvest also significantly reduced worm loads of IHHNV. Daily additions of a commercial probiotic to the sand bed surface for 4 weeks prior to clean seawater application provided no discernible benefit to IHHNV clearance. While clearly demonstrated to be capable of carrying IHHNV, the remediation measures examined suggest potential to ameliorate the infection transmission risks of P. helleri reared in PASF beds supplied with shrimp pond wastewater as a nutrient source.
