3 sty 2022 · This chapter describes in detail the life history of fish and the division and characteristics of the development period, the classification of the life history types of fish, the types of fish eggs, and the morphological characteristics and identification of larvae and juveniles.
Most bony fish eggs are referred to as telolecithal which means that most of the egg cell cytoplasm is yolk. [1] The yolky end of the egg (the vegetal pole) remains homogenous while the other end (the animal pole) undergoes cell division. [2] Cleavage, or initial cell division, can only occur in a region called the blastodisc, a yolk free ...
Fish eggs have macroscopic and microscopic characteristics that vary according to the reproductive strategies of the species. In ichthyoplankton samples, the identification of fish eggs can provide information on spawning areas and the biology of their dispersion.
1 lut 2010 · Studies on teleost fish reproduction assist the aquaculture industry in meeting the ever increasing demand for fish, by improving protocols for higher efficiency of egg production and enhanced viability of progeny.
1 sty 2023 · Fish eggs and larvae provide a relatively untapped source of biological material, increased by the recent improvements in techniques for rearing marine species. Apart from their intrinsic interest, experimentally based information on these early stages is required for further progress in the advancing fields of fish culture and fisheries research.
1 sty 2015 · Understanding what makes a good quality egg remains a challenge, but opportunities exist that should be taken to pinpoint the generic mechanisms defining the developmental potential of the egg and ultimately develop robust molecular markers of egg quality in fish.
This chapter summarizes information on the development of fish eggs and larvae, and introduces juvenile development. The chapter focuses on the changes that occur as the eggs develop, hatch into larvae, and finally transform into juveniles (ontogeny).
