— Small scale rearing of scleractinian coral larvae for experimental purposes has been practised for decades, but it is only in recent years that large scale larval rearing has been used as a means of providing corals for reef rehabilitation. This study aimed to develop optimal methods for rearing sexually propagated scleractinian corals from the broadcast spawning species Acropora hyacinthus a...

Microdera punctipennis Kasz (Coleoptera: Tenebrionidae) is a unique species that lives in the desert region of Central Asia and has adopted a nocturnal habit to survive the desert environment. Female adults are larger in size than male adults. The female/male ratio was 1.04:1. A rearing method using reused plastic bottles was used. The rearing conditions were 30 ± 0.5 °C, 30 ± 6% relative humid...

Clownfish is one of the most demanding-marine ornamental fish. Due to increased demand clownfish, wild clownfish catch has also been increasing, until reaching overexploitation condition. One way preserve existence this fish species and sustainably fulfil market by conducting a culture technique with advanced application using recirculating-aquaculture system, specifically larviculture. Thereby...

Oxygen provides the substrate for most ATP production, but also serves as a source of reactive oxygen species (ROS), which can induce cumulative macromolecular oxidative damage and cause aging. Pure oxygen atmospheres (100 kPa) are known to strongly reduce invertebrate lifespan and induce aging-related physiological changes. However, the nature of the relationship between atmospheric oxygen, ox...

One important step for the colonization of Ochlerotatus albifasciatus (Macquart) is to determine the optimal conditions for larval rearing, which makes possible the development of experiments comprising larval rearing in the laboratory. In this research the effect of diet composition on the development of O.albifasciatus was studied. For this purpose, cohorts of 20 first instars were reared usi...

Eggs of Anagasta kuehniella (Zeller 1879) are widely used for mass rearing of Trichogramma spp. and other parasitoids and predators, largely commercialized in many countries. The aim of this study is to evaluate the effect of carbon dioxide (CO2) originated from larval metabolism on the biological parameters of A. kuehniella. For that purpose, we assess the production of carbon dioxide (CO2) pe...

Rearing techniques are important to determine a successful honey bee production. Queen cell cup size may affect the acceptance rate of grafted larvae and queen’s size, which in turn influence quality colonies. The present study compared effect different queen sizes (8.0 vs 9.0 mm diameter) on morphometric characteristics bees. Sixty-five were each treatment. Larvae transfer was carried out five...

Eastern oysters, Crassostrea virginica, Northern hard clams, Mercenaria mercenaria, soft-shell clams, Mya arenaria, and bay scallops, Argopeclen irradians are routinely cultured in shellfish hatcheries throughout the northeastern United States for private sale, public stock enhancement and management programs. The culture process involves spawning adults, rearing the resultant larvae in large t...

This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

The use of irradiated hosts in mass rearing tephritid parasitoids represents an important technical advance in fruit fly augmentative biological control. Irradiation assures that fly emergence is avoided in non-parasitized hosts, while at the same time it has no appreciable effect on parasitoid quality, i.e., fecundity, longevity and flight capability. Parasitoids of fruit fly eggs, larvae and ...
