Fish breeding requires mature male and female fish in a suitable environment and season. There are two types of fish breeding: natural breeding which occurs instinctually in nature, and artificial breeding where humans control the environment and induce breeding. Factors that influence fish breeding include endocrine control, environmental conditions, physiological processes, nutrition status, stress levels, and ecological factors. Hormones released by the hypothalamus and pituitary glands govern key reproductive processes. Environmental conditions like temperature, photoperiod, tides, and water parameters also impact breeding. Physiological changes and energy mobilization are regulated by hormones as well.

that produces offspring, usually
animals or plants.
 Fish breeding is the breeding of

5. TYPES OF FISH BREEDING
 Two types-
1. Natural Fish Breeding: Instinct breeding in
natural breeding is known as natural fish
breeding.
2. Artificial Fish Breeding: The breeding method
by controlling environment and artificially
inciting male and female fish is known as
artificial fish breeding.

7.  Changes in environmental variables are transduced into effects on
reproductive processes through the hypothalamo–pituitary–gonadal (HPG)
axis.
 This begins with hypothalamic synthesis and synaptic release of peptide
gonadotropin-releasing hormones (GnRH) onto the gonadotropic cells of the
pituitary gland, where they stimulate the synthesis and release of FSH & LH
hormone.
 FSH is involved in stimulating the early stages of gamete development and
 LH in the control of maturational events

8. Physiological factors including nothing but the hormones.
Hormones govern,
 Migration
 Timing of reproduction
 Morphological changes
 Mobilization of energy reserves
 Elicit intricate courtship behavior

9.  Temperature
 Photoperiod
 Periodicity
 Tides
 Latitude
 Water depth
 Substrate type
 Salinity
 Exposure

12.  There are many factors have been identified as factor influencing
spawning, egg quality and reproductive performance of fish.
 All of the factors are play a vital role in the spawning, egg
composition, gonadal development, egg quality and reproductive
performance of fish directly and indirectly.
 All the factors mentioned above should be in a limit range for
successful reproduction.
