Those charged with determining the underlying cause of a disease outbreak have a wide variety of detective tools at their disposal.
Health & Welfare
The toxins from blue-green algae pose a threat to animal health and potentially to consumers if they are present in farmed product. Culture animals that ingest these toxins may not die, but can be weakened, increasing their susceptibility to pathogens.
Health & Welfare
To develop probiotics for marine shrimp, authors chose a bacterium with high growth velocity and great capacity to inhibit pathogens, among other traits.
Health & Welfare
Prevention through good hygiene, use of gloves and basic biosecurity procedures is the best method for reducing the risk of acquiring zoonotic diseases.
Intelligence
Off-flavor compounds produced by low-molecular-weight amine compounds present in fish are degraded into ammonia or other nitrogenous compounds during storage.
Health & Welfare
In biofloc production systems, ammonia-oxidizing bacteria process ammonia to nitrite, which provides substrate for nitrite-oxidizing bacteria that process nitrite to relatively non-toxic nitrate.
Health & Welfare
The authors evaluated Bacillus bacteria in a pink shrimp nursery and found it controlled Vibrio concentrations as well as a commercial probiotic.
Intelligence
Methods for analyzing histamine in fish, which causes many seafood-related illnesses, include test kits and high-performance chromatographic liquids.
Intelligence
Pasteurization of crustaceans, which can extend shelf life to years, preserves many of the chemical and physical characteristics of the original seafood and destroys most spoilage and many pathogenic bacteria.
Intelligence
The objectives of the smoking process are to uniformly impart the desired sensory characteristics to the product, extend shelf life and avoid the deposition of harmful compounds.
Responsibility
The use of phages is an alternative to antibiotics in the control of pathogenic bacteria. Phage therapy offers low-cost, low-toxicity treatment and quick bactericidal effects.
Health & Welfare
Microbial surveys of hatchery operations at Oceanic Institute found a strong correlation between hatchery success and cultivable bacteria levels in the water supplied to the larval-rearing systems.
Health & Welfare
Due to the inherent complexities of field testing, definitive laboratory-based test methods can better quantify probiotic benefits.
Intelligence
Each stage of crawfish processing contains potential human health hazards that must be addressed. Bacteria flourish under elevated temperatures but replication can be halted in cold storage.
Health & Welfare
Tilapia in culture are affected by bacterial, viral and parasitic pathogens. Disease impacts vary depending on both environmental and biological factors.
Health & Welfare
Both bacterial pathogens and chemical residues can affect the quality of farmed tilapia products. In production systems, Vibrio bacteria quickly proliferate following disease outbreaks.
