Effect of stocking density on larval performance and post-larvae settlement of clam Ruditapes decussatus (Linnaeus, 1758) in bivalve hatchery production [PDF]

E3S Web of Conferences
Larval rearing is a critical phase in bivalve hatchery production and plays a crucial role in the success of spat production. Therefore, understanding the effect of density on larval performance and post-larvae settlement is crucial for optimizing and ...

Larval connectivity and the international management of fisheries. [PDF]

PLoS ONE, 2013
Predicting the oceanic dispersal of planktonic larvae that connect scattered marine animal populations is difficult, yet crucial for management of species whose movements transcend international boundaries.

Fresh aquaculture sludge management with black soldier fly (Hermetia illucens L.) larvae: investigation on bioconversion performances

Scientific Reports, 2023
Aquaculture solid waste (ASW) is a nutrient rich material that can pose a significant environment challenge if not properly managed. This study investigated the potential of black soldier fly (BSF) larvae in converting this waste into biomass.

A Review of Spinosad as a Natural Product for Larval Mosquito Control

Journal of the American Mosquito Control Association, 2010
The effectiveness of spinosad for larval mosquito control is summarized based on available published literature and some heretofore unpublished studies. Spinosad is highly active against larvae of all mosquito species tested thus far. It is effective at similar dosages for all larval mosquito instars, with peak cumulative mortality occurring at 72 h ...

Establishment of a medium-scale mosquito facility: optimization of the larval mass-rearing unit for Aedes albopictus (Diptera: Culicidae)

Parasites & Vectors, 2017
Background Standardized larval rearing units for mosquito production are essential for the establishment of a mass-rearing facility. Two larval rearing units, developed respectively by the Guangzhou Wolbaki Biotech Co. Ltd.

Influence of maternal weight, age, larval feeding and their interactions on the hatchery outcomes of an Indian major carp (Labeo rohita, Hamilton 1822)

Aquaculture Reports, 2021
Broodstocks’ size (weight or length), age and larval feeding are crucial in the production of good quality gametes and larvae in any fish. Therefore, this study was conducted with two experiments to understand 1) effects of maternal weight and age, and 2)

Production of Larval Tanypodinae (Insecta: Chironomidae) in the Mud at Loch Leven, Kinross [PDF]

Proceedings of the Royal Society of Edinburgh. Section B. Natural Environment, 1976
SynopsisLife histories and production of the five common species of Tanypodinae (Pentaneura monilis, Procladius simplicistilus, P. crassinervis, P. choreus and Psilotanypus rufovittatus) in the mud at Loch Leven were measured from March 1971 to March 1972. The methods used to identify each species of larva are described.

Seasonal Occurrence and Relative Abundance of Marine Fish Larval Families over Healthy and Degraded Seagrass Beds in Coastal Kenya

Diversity, 2022
Seagrass beds provide critical nursery habitats and spawning grounds for new generations of fish. The habitats are under threat from human activities and climate change, and with that, an important ocean service is lost that limits fish production.
