Aquamimicry: A revolutionary concept for shrimp farming

: 12482

View of a grow-out shrimp pond implementing the Aquamimicry production approach. Technology has been met with success worldwide by balancing natural plankton. The prevalence of numerous diseases that affect the shrimp and prawn aquaculture industry has promoted the development of various health management strategies. Some include greater biosecurity and sourcing of specific pathogen free animals, and in more extreme cases, using chemicals and antibiotics. However, because of the nature of open pond aquaculture, where most farmed shrimp is produced globally, it is [...]


Zooplankton and Phytoplankton

: 12252

Zooplankton Zooplanktons are planktonic animals that range in size from microscopic rotifers to macroscopic jellyfish. The distribution of zooplankton is governed by salinity, temperature and food availability in the environment. The smallest zooplankton can be characterized as recyclers of water-column nutrients and often are closely tied to measures of nutrient enrichment. Larger Zooplanktons are important food for forage fish species and larval stages of all fish. They also link the primary producers (phytoplankton) with larger or higher trophic-level organisms. The zooplankton community [...]


Plankton Communities In Shrimp Monoculture, Integrated Biofloc System

: 4005

Summary: The authors performed a study to assess the plankton community in an integrated biofloc system with Pacific white shrimp, Litopenaeus vannamei, and red algae, Gracilaria birdiae. Once a week over seven weeks, phytoplankton were sampled in three tanks with monoculture of shrimp and nine tanks with integrated biofloc systems containing shrimp and algae. Shrimp survival was above 89% during the experiment. Feed conversion and final shrimp weight were better for the biofloc system than the monoculture system. A variety [...]


Shrimp feeding strategy

: 4605

A common observation of shrimp feeding behavior is that shrimp consume pellets for a relatively short time post-introduction to the pond. This unconsumed (refused) portion of the ration continues to decompose via hydration and biological/microbial activity. In some cases, the refused portion of the feed can exceed 60% of that offered. Despite failure to consume feed, shrimp can still benefit nutritionally from this process. For example, up to 75% of pellet carbon can be assimilated by other benthic organisms [...]


Multi-Phase Shrimp Production In Sun-Driven Honduran Ponds

: 25406

Summary: Honduras-based Grupo Granjas Marinas believes that large-scale production of rotifers and copepods and sequential pond inoculations, in combination with short shrimp growth cycles can significantly increase shrimp production while reducing dependency on other sources of protein in feeds. In its three-phase system with a central nursery pond, shrimp are transferred to larger areas as they grow, using production area efficiently without increasing densities. The multi-phase inventory management system has produced 15-g shrimp in eight weeks with an average [...]


Organism Size and Behavior in Penaeus vannamei

: 6452

Feed In response to a discussion on The Shrimp List titled “Feed Organism Size and Behavior in P.v.,” Durwood Dugger, one of the pioneers of shrimp farming in the Western Hemisphere and owner of BioCepts International, an aquaculture consulting company that concentrates on shrimp and lobster farming, wrote: Here are a few of my observations on the feeding behavior of Penaeus vannamei: 1. In some old Purina nutrition studies, I watched 40-gram broodstock clear newly hatched Artemia nauplii out of 120 L [...]
