The recent developments in aquaculture production of fish and shrimp have resulted in increased demands for Artemia cysts and biomass as valuable sources of life food. Solar salt works are suitable biotopes for the integrated exploitation of salt, Artemia and eventually fish or shrimp. Artemia may be present as a natural resource in local saltworks; however in some situations characteristics of the endemic strain might justify the introduction of another Artemia species to increase productivity.

Low nutrient availability is not the single factor limiting Artemia cyst productivity in salinas of NE-Brazil

Artemia production in NE-Brazil began in 1977 after a successful inoculation of Artemia franciscana (San Fransisco Bay, California, USA) in solar salt ponds in Macau (RN state) and was followed by a rapid natural dispersion of this crustacean to all saltwork areas in the region. Artemia is basically produced in extensive conditions as an opportunistic by-product collected from salt evaporation ponds. This type of approach has, however, brought about very unpredictable results, as is reflected in a drastic decline of cyst production occurring from 1982 onwards. Low nutrient concentrations and a drop in primary productivity have been suggested as possible causes for this decline. In order to provide a...

Decapsulated Artemia cysts have been evaluated as a direct food source for larvae of the carp Cyprinus carpio L. All decapsulated cyst diets gave excellent survival of carp larvae during the first two weeks of culturing. Unlike traditionally brine-stored decapsulated cysts, dried Artemia embryos provided growth results comparable to those obtained with freshly hatched Artemia nauplii. Furthermore, except for Artemia embryos that lost their hatchability after long-term storage in air, several other inactivation treatments, simulating improper harvesting and processing of cysts, did not produce a significant decrease in the nutritional quality of the decapsulated...

In recent years, there has been a growing awareness of the hydrobiological aspects of the solar salt production process. Saltworks are man-managed artificial ecosystems that are highly vulnerable to biological disturbances, including uncontrolled proliferation of microalgae resulting in a reduced evaporation and contamination of the salt with gypsum and insoluble organic materials.Optimal production of solar salt, both in terms of quality and quantity, requires a well-established balance between the primary and secondary producers, with brine shrimp Artemia grazing on phytoplankton constituting the major interaction. In this paper, we discuss the beneficial role of Artemia in balancing the hydrobiological activity of...

The effect of dietary phosphatidylcholine in postlarval penaeid shrimp: 2. Preliminary culture results

Tackaert, W.; Camara, M.R.; Sorgeloos, P..

Although dietary phospholipids (PL) and particularly phosphatidylcholine (PC) have been found to enhance growth and survival in penaeid shrimp, precise requirements have yet to be established. Substantially variable responses of feeding PL have been noticed in crustaceans in relation to the growth stage of the animals and the composition of the other dietary ingredients. In several shrimp feeding trials phospholipids of unspecified composition, have been used, such as crude lecithin, as a result of which it is difficult to draw conclusions with regard to the optimal levels/types of dietary PL required by penaeid shrimp. This paper is part of a broad study which aims to assess the dietary effect of different levels/types of purified PL in marine fish and...

The results are presented of a feeding experiment conducted with post-larvae of Penaeus monodon and P. vannamei using formulated dry feeds in which Artemia biomass was incorporated. The total and partial substitution for Artemia nauplii were evaluated. Survival rates in the experiment were not very high, indicating that nutritionally balance dry diets do not support the same growth as Artemia nauplii, which must contain a particular ingredient yet to be identified

A standard method has been developed to produce F1-generation cysts from different zygogenetic strains and their cross-breeds. The F1 cysts were used to determine the quantitative heritability of the following characteristics: cyst hatchability, cyst diameter, larval growth, and temperature resistance of the freshly-hatched nauplii.Data are given for cysts produced from nine strains and seven cross-breeds. Important differences for all characteristics studied were noted between the cross-bred and the parental strains.

Using cyst material produced in an indoor cyst production system from 4 Artemia strains belonging to the species A. franciscana (San Francisco Bay, California, USA; Macau, Brazil; Great Salt Lake, Utah, USA) and A. parthenogenetica (Lavalduc, France), different factors were studied that affect dormancy in brine shrimp cysts. Preliminary experiments under varying (a)biotic culture conditions revealed an interaction between environmental conditions and hatching characteristics. Results obtained under better-defined conditions demonstrated a significant positive correlation between the amount of food available to the adult Artemia populations and the hatchability of their encysted...

The worldwide distribution of the brine shrimp Artemia , in a variety of isolated biotopes with different ecological conditions, has resulted in the evolution of many geographical strains. Among these strains, substantial differences have been demonstrated in their nutritional quality and fitness, providing a basis for the selection of strains suitable for aquaculture. The Tanggu Saltworks (Tianjin, China) provide a unique environment for the production of Artemia . Unlike most other biotopes, they are characterized by a high primary productivity providing abundant food to sustain large populations of Artemia . Both laboratory studies and field observations, however, indicate that the local...

Vanhaecke, P.; Tackaert, W.; Sorgeloos, P..

An updated list of more than 350 Artemia sites is provided. It includes geographical coordinates of the sites and available data on the mode of reproduction of the locally occurring brine shrimp.The geographical distribution of Artemia is related to different types of climate. The classification of climate according to Thornthwaite provides a good correlation with the geographical occurrence of Artemia , as a result of which the world distribution pattern of Artemia can be predicted. Moreover, areas with possible Artemia sites and areas suited for transplantation and/or inoculation with Artemia can be identified on the basis of water balance...

Quynh, V.D.; Lavens, P.; Léger, P.; Tackaert, W.; Sorgeloos, P..

Artemia cysts collected from inoculation experiments in Cam Ranh salterns are evaluated for their potential use in aquaculture. Cyst biometrics, hatching quality, naupliar fatty acid profile and naupliar growth were measured and compared to reference Artemia strains. Cyst characteristics reveal that the parthenogenetic strain (PR China) used in inoculations, was eliminated from the environment and that the remaining brine shrimp are likely to be composed of Macau and Great Salt Lake Artemia strains, and of their cross-breds. Differences in cyst diapause deactivation characteristics between Macau and Great Salt Lake Artemia may have resulted in the disappearance of Macau...

Bosteels, T.; Tackaert, W.; Van Stappen, G.; Sorgeloos, P..

A fluidized bed dryer for processing Artemia cysts at the temperatures above 40°C is described and evaluated. The design is directed towards electronic temperature regulation and optimal design of the drying unit. The described fluidized bed dryer proves to be reliable for cyst processing, using inflow air temperatures up to 90°C. The use of this elevated temperature ensures a higher drying rate, resulting in a drying capacity more than 4 times higher than when using inflow air of 40°C. Electronic temperature regulation resulted in a large flexibility of the temperature regime inside the drying unit.

Abelin, P.; Tackaert, W.; Sorgeloos, P..

Unlike Artemia nauplii which are used extensively as convenient live feed in aquaculture, large-scale utilization of Artemia juveniles and adults (biomass) is still very limited and in most cases restricted to those operations which are located near an Artemia production site. Currently applied techniques for preservation of Artemia biomass (e.g. blast-freezing or drying) are often cost prohibitive and in several cases not applicable at the remote and scattered sites where the Artemia biomass is available. An inexpensive technique which can be readily applied under field conditions and allowing to stabilize and retain the nutritional quality of...

Pector, R.; Tackaert, W.; Abelin, P.; Ollevier, F.P.; Sorgeloos, P..

African catfish (Clarias gariepinus) larvae were fed on five preparations of decapsulated Great Salt Lake Artemia cysts: 1) dried (35°C, 6 h) and UV-irradiated cysts; 2) heated cysts (80°C, 10 min); 3) brine dehydrated and UV irradiated cysts; 4) micro-bound diet 1(with intact decapsulated cysts used in diet preparation 1); and 5) micro-bound diet 2 (with crushed and shifted decapsulated diet used in diet preparation 1). The larvae were fed from the first day after yolk-sac resorption (fourth day after hatching). After a 14-d rearing period, larvae fed on dried or heated decapsulated cysts or micro-bound diet 1. Feeding micro-bound diet 2 resulted in a significantly lower average gain in weight as compared to the other...

Among the live diets used in the larviculture of fish and shellfish, the brine shrimp Artemia nauplii constitute the most widely used food item; i.e., over 700 metric tons of dry Artemia cysts are annually marketed worldwide for on-site hatching into 0.4 mm nauplii.Although the use of Artemia appears to be simple, considerable progress has been made in the past decade in improving and increasing its value as a larval diet for marine fish larvae. The improvements include: identification of the most appropriate strains and batches; new techniques for cyst disinfection; decapsulation and hatching; and enrichment and cold storage of nauplii. Using particulate or emulsified products rich in highly...
