New techniques, peptide treatments aid intensive shrimp farm in Ecuador
The PescaMaris shrimp farm in Ecuador uses fish peptide isolates to accelerate probiotic bacteria growth and improve water quality.
Shrimp sampling method improves stocking process
Accurate estimates of shrimp populations and size variability by sampling can help managers make informed decisions that reduce feeding costs and improve system performance.
Working with fish, limiting zoonotic diseases
Prevention through good hygiene, use of gloves and basic biosecurity procedures is the best method for reducing the risk of acquiring zoonotic diseases.
Norwegian salmon smolt farms embracing RAS to raise production
Smolt production in Norwegian hatcheries will likely increase during the next decade to answer salmon grow-out needs. Farmers are converting existing flow-through systems to partially or fully incorporate recirculation technologies.
Tilapia farming faces expansion issues in Thailand
Thailand’s tilapia industry has been able to grow into a thriving sector thanks to technological advances and knowledge sharing.
Testing finds resistance to WSSV in shrimp from Panamanian breeding program
In a challenge test under controlled conditions using a severe strain of the virus, resistance to WSSV was shown in shrimp supplied by the Camaronera de Coclé, S.A. L. vannamei genetics program.
Ring tests compare PCR results from diagnostic laboratories
The University of Arizona’s Aquaculture Pathology Laboratory oversees ring tests for a group of shrimp diagnostic laboratories in 10 countries.
Extruder design changes increase production capacity for small-diameter feeds
The authors designed changes for single- and twin-screw extruders that streamlined the extrusion process to achieve higher output rates for small-diameter aquafeeds.
Botanical extracts improve productivity of shrimp, pangasius
In a study with pangasius, dietary administration of a blend of botanical extracts improved performance, reducing intensity of gill parasite infestation.
Tilapia production using biofloc technology
Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.
Spirulina meal, feeding attractant spare fishmeal in white shrimp diets
In a 10-week study of nursery-reared Pacific white shrimp performance, the inclusion of Spirulina meal allowed reduction of fishmeal up to 25 percent with no detrimental effect on shrimp growth performance.
New procedure controls TSV in white shrimp
The authors have established a procedure to reduce the impacts of Taura Syndrome Virus in the culture of Pacific white shrimp. The procedure focuses on avoiding the molting process of shrimp by limiting culture conditions.
Waddell Mariculture Center continues research on biofloc-based shrimp culture
Waddell Mariculture Center operates a commercial-scale prototype raceway utilizing minimal water exchange and biofloc culture to develop protocols for the indoor growout of Pacific white shrimp.
Establishing nitrifying bacteria in super-intensive biofloc shrimp production
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.
Red hogweed fights WSSV, promotes growth in tiger shrimp
A study carried out with the herb punarnava showed that it has antiviral properties in resisting WSSV infection and holds potential to promote growth in tiger shrimp. Increased survival was related to higher dosages.
Statistical modeling of field data can aid shrimp grow-out operations
In order to monitor and compare the performance levels of shrimp, statistical modeling of comprehensive field data collection from many commercial shrimp operations.
