High Quality Protein Concentrate Antibacterial Feed for Shrimp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mitigation strategies for Acute Hepatopancreatic Necrosis Syndrome (AHPND) in shrimp farming, caused by Vibrio species, are inadequate, leading to high mortalities and significant economic losses, and there is a need for a more effective alternative to traditional dietary supplements and antibiotics.
Innovation Solution
A microbially-enhanced protein-based diet containing a High Quality Protein Concentrate (HQPC) from fermented agricultural biomass, specifically soybeans, fermented with organisms like Aureobasidium pullulans, which is incorporated into the feed of shrimp larvae to enhance their resistance to Vibrio infections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mitigation strategies (probiotics, organic acids, essential oils, antibiotics) are used to control Vibrio infections, then Vibrio loads are reduced, but the effectiveness is insufficient and high mortalities continue to occur
Solution Approach 1:
The patent changes the chemical composition parameters of the feed by incorporating High Quality Protein Concentrate (HQPC) with specific protein content (60-80% dry matter basis) and controlled degree of hydrolysis (2-10%), which fundamentally alters the nutritional parameters to enhance shrimp immunity and reduce Vibrio infection severity
Solution Approach 2:
The patent creates a composite feed formulation combining HQPC with other feed ingredients in specific ratios (HQPC at 1-10% of total feed dry matter), producing a synergistic effect that provides both nutritional value and antibacterial protection against Vibrio species
2Productivity
If high stocking densities are maintained to increase productivity, then shrimp farm output increases, but Vibrio prevalence increases and mortalities worsen
Solution Approach 1:
The patent implements preliminary action by incorporating HQPC into the feed before infection occurs, which pre-establishes nutritional immunity and antibacterial protection in the shrimp, allowing high stocking densities to be maintained without the usual Vibrio-related mortalities
3Reliability
If dietary supplements and antibiotics are used to offset high mortalities, then survival rates improve temporarily, but the solution is not sustainable and eco-friendly
Solution Approach 1:
The patent applies self-service by using HQPC, which contains natural antibacterial compounds and nutrients that enable the shrimp to defend themselves against Vibrio infections, replacing the need for external antibiotics and creating a sustainable, eco-friendly solution that can be continuously applied without environmental harm
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The use of HQPC in the diet significantly reduces Vibrio infections in shrimp, improving their resistance and survival rates, even at high stocking densities, and demonstrates potential as a sustainable and eco-friendly solution for aquaculture feeds.
Implementation Method 1
a high quality protein concentrate that has antimicrobial properties in shellfish
Implementation Method 2
the feed composition improves the resistance of shellfish to Vibrio species associated with Acute Hepatopancreatic Necrosis Syndrome
