Chordata: Fish eggs and larvae

2017
This chapter describes the taxonomy of fish eggs and larvae. Most fish eggs and larvae are planktonic, and are commonly found in plankton net tows. Collectively these fish stages are referred to as ichthyoplankton. The chapter covers their life cycle, ecology, and general morphology.

Priorities during early growth of fish larvae

Aquaculture, 1997
Abstract The small and numerous eggs of most teleost fishes develop into small larvae with little yolk, which is depleted soon after hatching. They are the smallest self-supporting vertebrates. When these larvae complete their morpho-functional systems necessary to escape from predators and to obtain external food with priority, their further chances

Immunity in fish larvae.

Developments in biological standardization, 1997
The route of immunization, dose and nature of antigens are relevant for induction of specific immune responses but they are particularly influenced by the state of immunomaturation of fish. It is difficult, however, to determine when the fish immune system has matured and, accordingly, when the fry can be successfully vaccinated.

Wound healing in fish larvae

Journal of Experimental Marine Biology and Ecology, 1982
Abstract Healing of skin lesions has been investigated in herring, Clupea harengus L., plaice, Pleuronectes platessa L., and salmon, Salmo salar L., larvae. Healing was observed in vivo and by histology, the main response being a mass migration of epidermal cells from the periphery of the lesion. Wound areas of 0.1–7 mm 2 closed in 4–12 h, the

The early stress responses in fish larvae

Acta Histochemica, 2016
During the life cycle of fish the larval stages are the most interesting and variable. Teleost larvae undergo a daily increase in adaptability and many organs differentiate and become active. These processes are concerted and require an early neuro-immune-endocrine integration.

Comparisons of calcium regulation in fish larvae

Journal of Experimental Zoology Part A: Comparative Experimental Biology, 2003
AbstractThe purpose of the present study was to compare the ability of larvae of different species, goldfish (Carassius auratus), zebrafish (Danio rerio), and ayu (Plecoglossus altivelis), to regulate their calcium balance. Whole‐body Ca2+ content and Ca2+ influx in the larvae of the three species, which were incubated in low‐ (0.02 mM), mid‐ (0.2 mM),

Nutrition of Marine Fish Larvae

Journal of Applied Aquaculture, 2003
ABSTRACT In the hatchery production of aquatic animals for aquaculture, livefoods such as diatoms; rotifer, Brachionus plicatilis and brine shrimp, Artemia salina, have been used throughout the world. However, such production requires large facilities, maintenance expenses, and labor to produce a desired amount of live foods constantly and reliably ...

Biological Monitoring: Fish Eggs, Fish Larvae, and Zooplankton

2018
To understand the processes linking environmental variability to fish population dynamics in marine ecosystems, the dynamics of lower trophic levels including zooplankton as fish prey resources needs to be studied. Furthermore, the spawning habitat is the place connecting the life history of spawning adults and offspring and thus reflects the ...

Fish larvae nutrition and diet: new developments

2009
Marine fish larvae fed microdiets have not, at this stage, matched the growth and survival performances demonstrated by larvae fed live feeds such as rotifers and Artemia. This chapter discusses the issues related to the use of microdiets as a sole or partial feed for marine fish larvae.

Opportunistic Cyclopoid Prédation on Fish Larvae

Canadian Journal of Fisheries and Aquatic Sciences, 1984
Exceptional spring spawning of yellow perch (Perca flavescens) in an inland coastal lake resulted in very high larval fish densities (up to 41 900/1000 m3) and facultative predation by adult female Diacyclops thomasi on newly hatched larvae (maximum predation density: 8740/1000 m3), as evidenced by cyclopoid attachment to fish larvae in field ...
