This manual is a practical guide to commercial scale seed production of blacklip abalone (Haliotis rubra) in NSW, Australia with specialized instruction on topics rearing and inducing spawning. The techniques described are geared to efficient and intensive production of abalone spat using small areas of land.
Results of ASA/China 1999 Feeding Trial 35-99-61
Feed particle size requirements for crucian carp of 2-cm to 7-cm total length were determined in a joint study by ASA and the Zhejiang Freshwater Fisheries Research Institute in Huzhou, China. Results were used to formulate feed size recommendations for fish farmers producing crucian carp using feed-based production technologies. Crumble feeds of size 0.5-mm and 1.0-mm are recommended for fry of 2-cm and 3-cm total length, respectively. Crucian carp fry can be weaned to a 1.5-mm extruded pellet at 5-cm total length.
As the Mediterranean production of marine cultured fish increases, the demand for good quality seed has been continuosly arising. To satisfy that increasing demand spawning quality and seed production success must be improved by controlling the nutritional quality of broodstock diets and first-feeding regimes
Intensive recirculating tank culture can produce high yields on small plots of land with little water use. However, recirculating systems tend to be energy intensive and require high capital investments. Therefore, to make them profitable it is important to increase efficiency through feeding management.
There have been many laboratory-made lipid emulsions used to enrich larval finfish prey such as brine shrimp and rotifers, as well as bivalve broodstock, larvae and post set. However, these emulsions can be time consuming to prepare and often lack shelf life, requiring daily preparation. A few commercial lipid emulsions and powders are readily available at a reasonable cost from many aquaculture suppliers.
Copepod fed fish larvae have higher growth rates and survival than rotifer fed larvae, possibly because of the less investigated mineral differences that exist between rotifers and copepods. n this study, the enrichment and retention of Se in rotifers fed Se enriched yeast were investigated
Live feeds are an integral component in the cultivation of most marine finfish species during larval stages. The first live feed that has demonstrated acceptability for most marine species, and which can typically be raised on a commercial scale, is the rotifer Brachionus spp.
The manual describes the major production techniques currently employed for the cultivation of the major types of live food commonly used in larviculture, as well as their application potential in terms of their nutritional and physical properties and feeding methods.
This FAO technical paper aims to increase global awareness and to guide and build capacity about the best practices currently available by providing senior and mid-level sturgeon hatchery staff with a practical tool for modern sturgeon hatchery practices and management
Healthy individuals of matured clownfish, Amphiprion nigripes and sea anemone,Heteractis magnifica were collected from the Agatti island lagoon. Larvae metamorphosed and took up parent colouration and comparatively high growth rate was observed when fed on algae enriched rotifer than those with poly unsaturated fatty acid (PUFA)
Specific storage conditions and handling procedures are usually left to assumption. This article is intended to provide some detailed discussion, and information references where possible, on the most common causes of degradation and waste of aquaculture feed on the farm
