“…"But a burning question remained largely unanswered: how to move from knowledge to action." We recently published a convenient polyculture system that controls a shrimp viral disease with a high transmission rate (Wang et al, 2021), which aligns well with the current trend worldwide of ending hunger using the biodiversity of nature-Collaborative problemsolving and an integrated food system can deliver seafood protein, sustainably, to a world that increasingly needs it (Hendriks, 2022).…”

“…Therefore, these limited resource farms, which cultivate shrimp to improve livelihoods, are more vulnerable to WSS outbreaks than industrial farms. Most of these small farms have suffered from financial collapse due to production losses caused by WSS outbreaks (Wang et al, 2021).…”

“…Furthermore, the system can control WSS outbreaks even when there are WSSV carriers in shrimp post larvae. Thus, smallscale farms can easily adopt this system to prevent WSS outbreaks without additional investment (Wang et al, 2021).…”

Seafood security is essential in modern society. In 2013, Bush and colleagues stated, ‘Aquaculture, farming aquatic organisms, provides close to 50% of the world’s supply of seafood, with a value of United States $125 billion. It makes up 13% of the world’s animal-source protein (excluding eggs and dairy) and employs an estimated 24 million people’. With the increase in the human population and reducing fishing resources, humans increasingly rely on aquacultural products as the primary protein sources for many countries. Aquacultural productivity has been improving in recent years, and in certain countries, the aquaculture output is more than the fishing output. For example, Chinese aquaculture production is more than fishing output, which provides one-third of animal protein. Thus, intensive aquaculture has become the main supply with global aquatic products (FAO). In recent years, it is estimated that each person consumption of aquaculture products is 130 kg in some countries (Iceland). Here, we illustrate the road blocker in farmed shrimp production and provide our resolution. The global pandemic of white spot syndrome (WSS), caused by the white spot syndrome virus (WSSV), bears a devastating economic loss in farmed shrimp production, thereby jeopardizing seafood security. Currently, there is no effective control for WSS. Conventional single-species intensive farming removes the spatiotemporal interaction between different species. We hypothesize that establishing the spatiotemporal interface of a predator–prey may control WSS outbreak. We search for the pathways for the mechanisms by which predator–prey species interact and compete across spatial scales to characterize WSSV dispersal at regional scales for the local spatiotemporal structure of viral transmission. Thus, we create a generalizable and turnable engineered ecosystem that provides a clear route to prosperity and well-being to harness the world’s aquatic “blue” food systems to help end hunger.

“…In addition, local wisdom to ensure sustainable shrimp farming and reduce the WSSV transmission rate by using lower stocking densities could constitute an alternative strategy. Those methods including crop rotation or polyculture with fish 162 and sea weeds can provide favourable pond conditions for shrimp and reduce the WSSV load in the water and sediment, and thus also subsequent transmission to susceptible hosts. Mitigation is crucial to control the WSSV transmission within the farmed system and beyond.…”

White spot syndrome virus (WSSV), the etiological agent of white spot disease (WSD), is a significant pathogen affecting shrimp farming industry worldwide. White spot syndrome virus is a generalist virus mainly infecting decapod crustaceans. The aims of this review were to: (1) Re-evaluate and update the status of reported WSSV host and vector species based on the methods used when detecting replication and transmission to shrimp and 2) make a critical evaluation of existing literature on the presence of WSSV in aquatic organisms and the potential role these organisms might play in the transmission of WSSV in pond systems and the wild. An evaluation of literature about WSSV reported host and vector species showed an increase from 33 families to 50 families including 11 families of non-crustacean hosts, proved the virus continues to spread beyond farmed shrimp and the shrimp pond environment.White spot syndrome virus transmission in the aquatic environment is complex as depicted in our model. Containment of WSSV in ponds and the natural environment is challenging, mainly because of its generalist nature and a lack of understanding about (1) WSSV transmission in the aquatic setting, (2) the route of WSSV transmission among species exist in the aquatic environment and (3) information on the transmission dynamics between WSSV in farmed crustaceans and non-farmed animals.

“…Pacific white shrimp Litopenaeus vannamei is the major cultured shrimp species around the world, which has considerable nutritional and economic values ( 25 ). With the rapid development of the shrimp farming industry and the popularization of intensive farming systems, shrimp aquaculture has been threatened by various pathogens that cause huge economic losses ( 26 , 27 ).…”

SH2-domain-containing protein tyrosine phosphatases (PTPs), belonging to the class I PTP superfamily, are responsible for the dephosphorylation on the phosphorylated tyrosine residues in some proteins that are involved in multiple biological processes in eukaryotes. The Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway transduce signaling responding to interferons and initiate cellular antiviral responses. The activity of the JAK/STAT pathway is generally orchestrated by the de-/phosphorylation of the tyrosine and serine residues of JAKs and STATs, in which the dephosphorylation processes are mainly controlled by PTPs. In the present study, an SH2-domian-contianing PTP, temporally named as LvPTPN6, was identified in Litopenaeus vannamei. LvPTPN6 shares high similarity with PTPN6s from other organisms and was phylogenetically categorized into the clade of arthropods that differs from those of fishes and mammals. LvPTPN6 was constitutively expressed in all detected tissues, located mainly in the cytoplasm, and differentially induced in hemocyte and gill after the challenge of stimulants, indicating its complicated regulatory roles in shrimp immune responses. Intriguingly, the expression of LvPTPN6 was regulated by interferon regulatory factor (IRF), which could directly bind to the LvPTPN6 promoter. Surprisingly, unlike other PTPN6s, LvPTPN6 could promote the dimerization of STAT and facilitate its nuclear localization, which further elevated the expression of STAT-targeting immune effector genes and enhanced the antiviral immunity of shrimp. Therefore, this study suggests a PTPN6-mediated regulatory approach from IRF to the JAK/STAT signaling pathway in shrimp, which provides new insights into the regulatory roles of PTPs in the JAK/STAT signaling pathway and contributes to the further understanding of the mechanisms of antiviral immunity in invertebrates.
