Abstract Background Enterocytozoon hepatopenaei (EHP) is an enteric pathogen that affects Penaeus vannamei and Penaeus monodon shrimp in many SE Asian countries. In the western hemisphere, EHP was reported for the first time in 2016 in farmed P. vannamei in Venezuela. Anecdotal evidence suggests that EHP is more prevalent in grow-out ponds where the salinity is high (> 15 parts per thousand (ppt)) compared to grow-out ponds with low salinities (< 5 ppt). Considering that P. vannamei is an euryhaline species, we were interested in knowing if EHP can propagate in P. vannamei in low salinities. Results In this study, we described an experimental infection using fecal strings as a source inoculum. Specific Pathogen Free (SPF) P. vannamei were maintained at three different salinities (2 ppt, 15 ppt, and 30 ppt) while continuously challenged using feces from known EHP-infected P. vannamei over a period of 3 weeks. The fecal strings, used as a source of EHP inocula in the challenges, was sufficient to elicit an infection in shrimp maintained at the three salinities. The infectivity of EHP in shrimp reared at 2 ppt, 15 ppt, and 30 ppt salinities was confirmed by PCR and histopathology. The prevalence and the severity of the EHP infection was higher at 30 ppt than at 2 ppt and 15 ppt. Conclusion The data suggests that fecal strings are a reliable source of EHP inoculum to conduct experimental challenges via the fecal-oral route. An EHP infection can occur at a salinity as low as 2 ppt, however, the prevalence and the severity of the EHP infection is higher at a salinity of 30 ppt.

Shellfish Allergy

Shellfish allergy affects 2% of the world’s population and persists for life in most patients. The diagnosis of shellfish allergy, in particular shrimp, is challenging due to the similarity of allergenic proteins from other invertebrates. Despite the clinical importance of immunological cross-reactivity among shellfish species and between allergenic invertebrates such as dust mites, the underlying molecular basis is not well understood. Here we mine the complete transcriptome of five frequently consumed shrimp species to identify and compare allergens with all known allergen sources. The transcriptomes were assembled de novo, using Trinity, from raw RNA-Seq data of the whiteleg shrimp (Litopenaeus vannamei), black tiger shrimp (Penaeus monodon), banana shrimp (Fenneropenaeus merguiensis), king shrimp (Melicertus latisulcatus), and endeavour shrimp (Metapenaeus endeavouri). BLAST searching using the two major allergen databases, WHO/IUIS Allergen Nomenclature and AllergenOnline, successfully identified all seven known crustacean allergens. The analyses revealed up to 39 unreported allergens in the different shrimp species, including heat shock protein (HSP), alpha-tubulin, chymotrypsin, cyclophilin, beta-enolase, aldolase A, and glyceraldehyde-3-phosphate dehydrogenase (G3PD). Multiple sequence alignment (Clustal Omega) demonstrated high homology with allergens from other invertebrates including mites and cockroaches. This first transcriptomic analyses of allergens in a major food source provides a valuable resource for investigating shellfish allergens, comparing invertebrate allergens and future development of improved diagnostics for food allergy.

Polyhydroxy Butyrate

Artemia sp. is a common natural feed for shrimps at the post-larvae stage and is characterized by poor lipid content. Therefore, Artemia is commonly enriched with specific nutrition, including biofloc. This contains some useful nutrients in the form of protein and polyhydroxy butyrate (PHB). The aim of this study was to analyze the effect of Artemia enriched with biofloc on the growth performance of black tiger shrimp, P. Monodon, and whiteleg shrimp P. vannamei. This research used acompletely randomized design (CRD), encompassing three treatments of feed and four replications. The tested treatments include: (a) Artemia sp. without enriched (b) Artemia enriched with biofloc, and (c) biofloc without Artemia, and the treatments were fed on black tiger as well as whiteleg shrimp post-larvae for 15 days. The results showed the significant effect of using  Artemia sp. enriched with biofloc on the growth of P. monodon and P. vannamei, but not on the survival rate. However, both parameters were significantly influenced for post-larvae shrimp at a dose of 30 mL biofloc. This served as a nutritional source by providing the best growth of 14.57 mg and 15 mg at a daily growth and survival rate of 0.86 mg day-1: 98% and 1.4 mg day-1: 99% for P. vannamei and P. monodon, respectively.

Abstract. Faisal TM, Akbar H, Putriningtias A, Putra SA. 2019. Short Communication: Community structure of prawns (Decapoda: Penaeidae and Palaemonidae) in mangrove inlets of Kuala Langsa, Aceh, Indonesia. Biodiversitas 20: 1306-1311. The aim of this research is to describe the structure of prawn community that found at mangrove inlets of Kuala Langsa (Aceh, Indonesia). The survey was done in August 2018. Sampling sites were defined as arbitrarily. Scope netting (mesh size 1 cm and diameter 100 cm) was used to sample the prawn community. Samples were analyzed and stored at The Primary Laboratory of Universitas Samudra, Kota Langsa, Aceh. Five species of prawns from two families (i.e., Decapoda: Penaeidae and Palaemonidae) were found, i.e., Penaeus monodon, Penaeus indicus, Metapenaeus monoceros, Penaeus vannamei, Palaemon sp. The most dominance species found is M. monoceros, and the most infrequently species found is Palaemon sp. Prawn community between sampling sites are found in a high level of similarity, with medium diversity and evenness index, and no dominance indicated.
