Controlling the concentration of bioflocs is one of the main concerns in aquaculture systems with Biofloc Technology (BFT). Biofloc accumulation deteriorates the water quality and can negatively affect the production rates of the farmed river shrimp. This study describes and characterizes the settling velocity distribution of bioflocs generated wit...

Cultivation of cyanobacterium Arthrospira sp. has been developed in many countries for the production of proteins, pigments and other compounds. Outdoor mass cultures are often affected by biological contamination, drastically reducing productivity as far as bringing death. This study evaluates the control of Branchionus sp. and Amoeba sp. with two...

Reductions of its natural populations have led to recent efforts in small-scale aquaculture of the freshwater prawn Cryphiops caementarius, either for conservation or commercial purposes. However, the lack of knowledge about its nutritional requirements has been one of the major obstacles for its successful culture. Given its importance, this study...

Its indiscriminate extraction and alterations of its natural environment, has put in danger of extinction the only commercial freshwater Palemonid present in Chilean inland waters. Even though this situation has awakened interest in studies which allow its controlled reproduction in captivity, currently little is known regarding basic reproductive...

The variation in saline requirements during larval development of Cryphiops caementarius establishes a particular coexistence in the culture systems between the shrimp larvae, the microalgae and Artemia nauplii. Although the technology for the mass production of freshwater prawn juveniles has advanced positively, the non-commercial availability of...

One of the emerging technologies that aims to optimize production and minimize environmental impact in aquaculture is biofloc technology (BFT). This technology controls ammonia buildup by adding carbon to encourage the growth of heterotrophic bacteria. This study aimed at describing and characterizing the composition, size, and sedimentation rate o...

This study aimed to evaluate and compare the effects of biofloc technology (BFT) and clear water (CW) on water quality physiological and productive performance of juvenile freshwater Northern River shrimp, Cryphiops caementarius under three stocking densities (100, 200, and 400 shrimp m⁻²). Shrimp with an initial body weight of 0.44 ± 0.07 g were s...

Over the last few decades, aquaculture has undergone a dramatic expansion in production, becoming a key source of food for people in many countries. Indeed, aquaculture has become extremely important for food security. However, the rapid expansion has led to many concerns, such as the effects of water shortages, pollution, disease and the depletion...

importancia, este trabajo describe y caracteriza el proceso completo de maduración gonadal en hembras de Cryphiops caementarius, en base a cambios en la morfología externa e interna del ovario. Hembras adultas extraídas del río Limarí, fueron disectadas y sus ovarios removidos y preparados para análisis histológicos. Tejido fibromuscular divide el...
