Abstract

The accumulation of organic matter at the bottom of the pond greatly affects nutrient metabolism, feed efficiency, growth and productivity in giant tiger prawn cultivation. One of the causes is improper pool bottom construction The purpose of this study was to compare the growth performance and efficiency of protein utilization in giant tiger prawns consuming artificial feed supplemented with multi-enzymes and reared in tarpaulin ponds constructed between not and using the faecal chamber (FAMBER) or the space of metabolic waste and unconsumptioned feed (SOMECOF) at the bottom of the pond with a recirculating aquaculture system (RAS). A tarpaulin pond with a diameter of 3 m and a height of 100 cm filled with 80 cm of seawater. The tarpaulin pond is equipped with a transparent plastic roof, seawater and aeration installation, and a filter in the water pump tank. The average body weight of the experimental prawn used were 8-9 g. The feed given is pellet type artificial feed supplemented with multi-enzymes at a dose of 30 cc/kg of feed. The frequency of feeding were four times a day, namely at 07:00; 12:00; 17:00 and 22:00 with a dose of 5%. The parameters measured were growth performance including growth, condition factors and feed efficiency, while the efficiency of protein utilization included protein content, protein efficiency ratio, amino acid profile, index and score of essential amino acids of feed and experimental prawn. Data analysis was done descriptively. The results showed that all parameters of growth performance and efficiency of protein utilization in tiger prawns reared in tarpaulin ponds using FAMBER were better than those without FAMBER. Based on the results of the study, it was concluded that keeping giant tiger prawns in a tarpaulin pond using a FAMBER is better than not using a FAMBER.

Abstract

Graphical Abstract     Highlight Research 1. The dsRNA application should correspond to the developmental stages of shrimp2. Immersion method was commonly used for larvae for handling many individuals3. Injection technique effectively delivered dsRNA to cells but was unsuitable for large-scale4. Oral administration of pellet-enriched dsRNA was applicable to apply on shrimp larvae, juveniles, and broodstocks     Abstract RNAi technology offers a novel powerful approach to silence gene expression by introducing double-stranded RNA (dsRNA) into the cell to degrade the mRNA at the post-transcriptional stage. An administration method of dsRNA delivery is one of the main considerations in applying the dsRNA vaccine for controlling pathogen infections. This mini-review was focused on the evaluation of three different methods (immersion, injection, and oral administration) of VP15-dsRNA vaccine delivery to the tiger shrimp post-WSSV challenge test. The immersion method was generally applied for the larval stage of tiger shrimp and seemed to be a simple technique for a large number of individuals in a small tank. The VP15-dsRNA application by immersion improved the survival of tiger shrimp larvae by 3.9% compared to the control groups. The injection technique was an effective way to deliver dsRNA to the cell, but it is difficult to apply in a large number of individuals or populations. The injection of VP15-dsRNA increased significantly the survival rate, proPO, and THC of tiger shrimp. A higher survival rate (75%) was exhibited in tiger shrimp injected with in vivo and in vitro VP15-dsRNA than in the control. Oral administration by pellet-enriched VP15-dsRNA was a useful way for larvae, juveniles, and broodstocks, but it has limitations since the pellet leaches into the water. The application of the VP15-dsRNA vaccine on the feed significantly enhanced the 26.7% higher survival rate compared to the control. The higher survival was also supported by a higher number of THC. The three VP15-dsRNA delivery methods provide potential approaches to increase tiger shrimp resistance to control pathogen infection
