A review of the application of probiotics in shellfish aquaculture, methods of administration, mode of actions and their enhancing effects. 

Guatemala’s shrimp-farming growth is due to a highly intensive system of small ponds and shorter cycles. Production of close to 25,000 metric tons is expected in 2018. 

Pond microbial communities are a critical and often overlooked component of aquaculture ecosystems. Bacterial amendments like probiotics provide significant support to shrimp farmers around the world. 

This study evaluated a commercially available prebiotics and probiotics under conditions simulating commercial production in hybrid catfish. Results showed that the various dietary treatments did not have any significant effects on processing characteristics or composition. 

Effective implementation of biosecurity protocols in shrimp farming requires awareness, discipline and a commitment by farm owners to implement them. The authors take a close look at intensive nurseries and how to exclude pathogens, predators and competitors. 

Results of a feeding study supplementing probiotics in the diet showed that when the Bacillus species were complemented in an appropriate concentration into feeds, the growth and feed efficiency of whiteleg shrimp could be improved. 

The application of probiotics, prebiotics and lipopolysaccharides has shown positive results with farmed shrimp, and is a very promising field, but more research is needed to clarify and foresee the molecular impact of these biological entities. 

Juvenile carnivorous African catfish performed well in biofloc-based systems, which could help produce better quality and more disease-resistant seed of this important aquaculture species and support the expansion of African catfish farming industry. 

In the second Pecha Kucha presentation from the Global Aquaculture Alliance's annual GOAL conference in Dublin, Ireland, Fanny Giudicelli of Marine Akwa talks about how marine probiotics, derived from seaweed, can help the industry's efforts in combatting infectious diseases. 

Aquamimicry simulates natural, estuarine production conditions by creating zooplankton blooms as supplemental nutrition to the cultured shrimp, and beneficial bacteria to maintain water quality. Better-quality shrimp can be produced at lower cost and in a more sustainable manner.  

Un estudio fue llevado a cabo para medir los efectos de probióticos comerciales en camarón blanco del Pacífico en un modelo de desafío a AHPND estandarizado bajo condiciones controladas de laboratorio. Los resultados muestran que los tratamientos de probióticos por sí mismos tienen efectos beneficiosos, como una mayor supervivencia y signos histológicos de regeneración de hepatopáncreas. 

A study was conducted to measure the effects of commercial probiotics on Pacific white shrimp in a standardized AHPND challenge model under controlled laboratory conditions. Results show that the probiotics treatments by themselves have beneficial effects, such as higher survival and histological signs of hepatopancreas regeneration. 

Experiments were conducted to evaluate the potential survival and growth benefits of three multi-strain probiotics in three different stages of juvenile rohu (hatchling to advanced fry). Results showed beneficial effects of the probiotics treatments for the hatchling and fry stages, but not for later stages. 

The Oceanic Institute of Hawaii Pacific University has been working to develop methods to culture yellow tang, a top species collected for the aquarium trade. The fish under culture are living longer as practices improve. 

In early 2014, a trial to evaluate the effects of a mixture of Bacillus strains on early mortality syndrome bacteria during the larviculture and nursery phases for shrimp was carried out at a commercial hatchery in Mexico.
