Protein Requirement in Granulated Microdiets for Olive Flounder (Paralichthys oivaceus) Larvae

The optimal protein requirement in granulated microdiets was determined for larval olive flounder (Paralichthys olivaceus). Five granulated microdiets containing 42 to 58 % protein levels at a
constant energy level were prepared. Dietary protein requirement was estimated to be 55.4 % based on the RGR of the larval olive flounder.

Can canola meal and soybean meal be used as major dietary protein sources for kuruma shrimp, Marsupenaeus japonicus?

Results obtained in using the experimental conditions of this trial show that canola meal and soybean meal could be effectively utilized as major protein sources by kuruma shrimp Marsupenaeus japonicus. The dietary fishmeal could be reduced to only 6% (85% replacement) with a blend of canola meal and soybean meal, and supplementation of methionine, lysine, phytase and fish soluble without compromising growth, feed utilization, body composition and health of juvenile kuruma shrimp.

Effects of on-demand feeding on sea urchin larvae (Paracentrotus lividus; Lamarck, 1816), development, survival and microalgae utilization

Results of this study suggest that the use of the variable method improves the larval survival and development and also it reduces resource consumption (phytoplankton, seawater use and work effort), which in turn could potentially improve the hatchery production of P. lividus.

Effects of a mix of Bacillus sp. as a potential probiotic for Florida pompano, common snook and red drum larvae performances and digestive enzyme activities

This experiment suggests that a mix of Bacillus sp. can promote growth through an early maturation of the digestive system during the early larval stages of pompano and snook.

A novel approach to introduce nutrients into the fish egg; the effect of egg taurine on first feeding gilthead sea bream (Sparus aurata) performance

The study demonstrated the potential of electroporation as a novel high throughput approach to introduce taurine and/or other critical nutrients into the developing eggs and a potential alternative to costly broodstock dietary supplementation.

Nutritional programming through broodstock diets to improve utilization of very low fishmeal and fish oil diets in gilthead sea bream

The main objective of this study was to research in the potential value of fatty acids as modulators of early nutritional programming in marine fish for a better utilisation of VO/VM.

A review of maturation diets for mud crab genus Scylla broodstock: Present research, problems and future perspective

This paper reviewed the studies on the maturation diets for mud crab broodstock, genus Scylla and compared independently to identify their effect on reproductive performance and larval quality.  This review also discusses the problems in the previous studies for the potential future research to develop very high quality and cost-effective formulated diet for the enhancement of broodstock and seed production technology. Information from this review can be useful in developing a better quality of crustacean broodstock’s diet for commercial hatchery production.

Hydrodynamic starvation: Why so many fish larvae perish after hatching

This study uncovered the reason why 90 percent of fish larvae are biologically doomed to die mere days after hatching. The research suggests that \"hydrodynamic starvation,\" or the physical inability to feed due to environmental incompatibility, is the reason so many fish larvae perish.

Progress on larval and juvenile nutrition to improve the quality and health of seawater fish: a review

Toshio Takeuchi, Tokyo University of Marine Science and Technology, Konan, Minato, Tokyo, 108-8477, JapanThis review collates the efforts made during the past two decades in larval nutrition – focusing on advances made in the use of certain nutrients, such as docosahexaenoic acid, vitamin A derivatives, and taurine that are important for the mass production of seawater fish larvae and juveniles–with an aim to improve the quality and health of fish.

Fish larval nutrition and feed formulation: knowledge gaps and bottlenecks for advances in larval rearing

Abstract: Despite considerable progress in recent years, many questions regarding fish larval nutrition remain largely unanswered, and several research avenues remain open. A holistic understanding of the supply line of nutrients is important for developing diets for use in larval culture and for the adaptation of rearing conditions that meet the larval requirements for the optimal presentation of food organisms and/or microdiets. The aim of the present review is to revise the state of the art and to pinpoint the gaps in knowledge regarding larval nutritional requirements, the nutritional value of live feeds and challenges and opportunities in the development of formulated larval diets.

Juvenile rainbow trout responses to diets containing distillers dried grain with solubles, phytase, and amino acid supplements

Distillers dried grain with solubles (DDGS) was evaluated in juvenile Shasta-strain rainbow trout Oncorhynchus mykiss diets during a 36-day feeding trial. Two experimental diets containing either 10% or 20% DDGS with supplemented amino acids (lysine, methionine, isoleucine, and his-tidine) and phytase were compared to a fish meal-only control diet. The results suggest that DDGS, even if supplemented with essential amino acids and phytase, will lead to decreased juvenile rainbow trout growth at dietary concentrations of at 10% or greater

Feed Particle Size Requirements for Crucian Carp Fry

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
