“…The requirement for a particular nutrient can be defined from a physiological point of view as the nutrient intake needed to fulfil a physiological role (Izquierdo & Lall 2004). However, the design and formulation of diets requires translation of the nutritional requirements into the nutrient content in the diet (Kolkovski et al. 2009).…”

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.

“…Micro-extrusion marumerization (MEM) and particleassisted rotation agglomeration (PARA) have recently been introduced for the development of microparticulate diets for fish larvae [8]. These techniques were originally developed by the pharmaceutical industry.…”

“…In addition to new techniques for developing microparticulate diets, technologies have also been developed for microparticulate diet feeding. Because of the lack of motility and rapid sinking in the water column, high-frequency feeding is required for an inert diet [8]. A low frequency of feeding during the period of microparticulate diet feeding will prolong the weaning period and may lead to lower survival and higher consumption of the diet, thus increasing the production cost of juveniles.…”

“…Another problem is that microparticulate diets should be kept below room temperature before feeding to prevent denaturation of nutrients, yet the temperature inside the container of the belt feeder often reaches as high as 30-40 °C in fish culture sites. In addition, high humidity in the hatchery often makes diet particles aggregate together and clog the belt feeder [8]. Even after feeding in the fish tank, low-density diet particles often float on the surface of the water column and are not eaten by the fish.…”

“…Even after feeding in the fish tank, low-density diet particles often float on the surface of the water column and are not eaten by the fish. Several new delivery systems have been developed for feeding microparticulate diets such as an underwater feed delivery system and an automatic microparticulate diet dispenser [8]. The former was developed in Norway to deliver diet particles mixed with water by flushing into the water column through several narrow tubes from the container.…”

associated with these problems in order to develop new types of feed.The development of artificially formulated diets for fish juvenile production is a long-held goal of the fish feed industry. However, there are many problems with the existing live food (rotifer and Artemia) used for rearing marine fish larvae and juveniles, including difficulties with stable production due to the marked effect of water temperature on rotifer culture and the need to collect natural eggs to produce Artemia. Considerable effort is needed to culture live food, and the lack of some nutrients, particularly DHA, necessitates enrichment. The development of microparticulate diets is increasingly regarded as a solution to these problems. Recent reviews on microparticulate diets for fish larvae cover a wide range of topics related to larval nutrition [3,4]. However, these are mainly based on findings from European fish species, and there is little information on invertebrate species. Therefore, this review summarizes some experiences with microparticulate diets studied and developed for the larvae and juveniles of three species: Pacific bluefin tuna Thunnus orientalis, abalone Haliotis sp., and Japanese spiny lobster Panulirus japonicus in the phyllosoma stage. These are very important species for commercial fisheries in Japan and considerable progress has been achieved in terms of their juvenile production technology such as development of microparticulated diets for larvae and juvenile of these species in this decade. Types of microparticulate dietThe diets must be very small particles (100-500 μm), have an appropriate specific gravity (floatability), release a minimal amount of nutrients, and be readily digested and absorbed by fish larvae and juveniles. Three types of Abstract Despite considerable progress in understanding the nutritional requirements of marine fish larvae and processing technology of dietary ingredients, microparticulate diets, which can completely replace live food such as rotifers and Artemia, remain to be developed. Recent reviews have generally covered a wide range of aspects of fish larvae nutrition and the formulation of microparticulate diets as well as technical limitations. However, most of them focused on widely cultured finfish species such as seabream and seabass, but not invertebrate species and novel finfish species. This review describes the recent development of microparticulate diets for the larvae and juveniles of three species of aquatic seawater animals: Pacific bluefin tuna, abalone, and Japanese spiny lobster phyllosoma.
