PROMICROBE: Microbes as positive actors for more sustainable aquaculture

The project starts from the concept that the host microbial community (MC) is influenced by the host itself and by the microbial community of the system in which the host is living. It is anticipated that there is a reciprocal interaction between the different compartments of the system in every stage of the life cycle.

Effect of broodstock nutrition on reproductive performance of fish

 An improvement in broodstock nutrition and feeding has been shown to greatly improve not only egg and sperm quality but also seed production. Gonadal development and fecundity are affected by certain essential dietary nutrients, especially in continuous spawners with short vitellogenic period

Nutritional requirements of marine fish larvae and broodstock

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

Settlement, Growth and Survival of the Donkey’s Ear Abalone Haliotis asinina (Linne) in Response to Diatom Diets and Attachment Substrate

The effect of feeding four diatom diets (Amphora sp., Navicula ramosissima, Amphora sp. + N.ramosissima, and mixed diatoms) and two attachment substrates (PP+CCA: polyvinyl plates with crustose coralline algae; PP-CCA: polyvinyl plates without crustose coralline algae) were determined for seed production of abalone, Haliotis asinina

The problem of meeting dietary protein requirements in intensive aquaculture of marine fish larvae, with emphasis on Atlantic halibut (Hippoglossus hippoglossus L.)

Atlantic halibut are slow feeders and may thus suffer more from nutrient leaching than species eating more rapidly. Feed formulation techniques affect dietary protein leaching, and in this paper, different techniques and their impact on feed properties are described

In vitro digestibility of water-soluble and water-insoluble protein fractions of some common fish larval feeds and feed ingredients

In vitro methods have previously been utilised for the rapid and reliable evaluation of protein digestibility in fish. In this study we used in vitro methods to compare the digestibility of various live and artificial larval feeds and feed ingredients

Use of formulated diets as replacements for Artemia in the rearing of juvenile American lobsters (Homarus americanus)

In recent years, commercial Artemia replacement (CAR) diets have been developed and marketed for use in aquaculture production of marine shrimp. Three separate experiments assessed the utility of rearing American lobsters on these shrimp CAR diets

THESIS: Digestive profile and capacity of the mud crab (Scylla serrate). By Marko Pavasovic, Queensland University of Technology

A key focus of the current study will be to use the mud crab, Scylla serrata, as a model system to determine the capacity of cultured crabs to digest protein and various classes of carbohydrates incorporated into formulated diets. Another goal is to determine if mud crab digestive processes or feed digestibility are altered by changes in the protein or carbohydrate profiles in the diet

Rotifers as live feed in shrimp hatcheries, Is still an open option?

M.R.Kitto* and Regunathan C.** *Assistant Professor, Faculty of Marine Science, King Abdulaziz University, P.O. Box : 80207, Jeddah 21589, Saudi Arabia. Email: **Aquaculture Specialist, 228 B, East of DVD School, Kottar, Nagercoil, Tamil Nadu, India. E mail : Author) Authors of this review feel that the cost for culturing live algae used for enrichment could be drastically curtailed in the new millennium by using agricultural fertilizers and the partial supplementary utilization of underutilized waste products like sterilized sardine pastes or sugarcane molasses extracts or rotifer culture media waste water and / or seaweed liquid fertilizer extracts of Ascophyllum or sterilized trash fish waste water. Modern technologies where probiotics are involved in shrimp larviculture, employing rotifers as starter live feed holds much promise as live-feed mediated delivery of probionts efficiently incorporates the benign bacteria to the targeted shrimp larvae...

The influence of nutrition at the larval stages in marine fish

José Luis Zambonino-Infante, Giorgos Koumoundouros, Amos Tandle Larval deformities are mostly induced at the hatchery stage by several environmental factors (abiotic factors), diseases and some dietary components. This paper investigates the potential influence of some dietary vitamins in the appearance of malformations. The impact of the dose of the vitamin mix recommended by NRC93 was evaluates, and three vitamins in particular were studied: Vitamin A (retinol acetate), vitamin D (1,25 dihydroxycalciferol), and vitamin C (ascobyl polyphosphate).

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
