please suggest me some topics of masters research pertaining to fish breeding..?

Answer 1

There has been a lot of on going discussion of the impact of water temperature on the ratio of the sexes among livebearer fry. To my knowledge there has been very little actual research, either lab or field, to prove or disprove any temperature impact. That's something many fish farmer would love to know.

Answer 2

A couple of things come to mind. These are all off the top of my head.

1) In various frog species, the death of a tadpole in a pool of water can release a trigger chemical that causes other tadpoles to go through a growth spurt. The thinking is that the larger tadpole is harder to prey upon. The drawback is this lengthens the metamorphosis of the frog. Are there similar instances in fish species where the death of a sibling, neighbor, etc. can trigger a physiological change due to an external stimulus?

2) Many small males of various species impersonate females in order to mate. They escape the notice of dominant males and secretly fertilize eggs of females. These "sneaker males" have been documented in a lot of bass/sunfish species. What factors influence success rate of these female impersonators?

3) Archerfish align themselves almost vertically with the water surface to minimize light refraction when shooting at a target. Are there various chemicals/waste materials that aren't directly harmful to the fish, but would alter the refraction of light through the medium so as to throw off their aim?

Answer 3

Hmm, there are lots of things you could do research on such as effect of various temperatures on sex ratios and development of the eggs, or simply what spawning triggers (temperature, pH, barometric changes) affect a specific fish.

Answer 4

teach specific animals that is Monogamist. And evaluate in the event that they could be a perdator or in the event that they could be a prey. i actual ask your self if coyotes are Monogamist. One time wittnessed how they are able to have a tendency to an injured Coyote and guard it while traveling lower back to that is Den. i come across that magnificent because of the fact while a %. of canines have a celebration injured they are going to pass away it in the back of and haven't any concern in any respect. That lead me to have self belief Coyotes are very distinctive from canines or Wolves I in basic terms ask your self why.

Answer 5

It really depends on the fish! for instance, Goldfish are harder to breed than Guppies.

Answer 6

if you givve you fish time, and water, they will breed by themselves. also make sure you have a boy and a girl, otherwise it will never work. this website has all you need to know about how to get those fish of yours to have babies. http://fins.actwin.com/mirror/breeding.html i hope all of my advice is helpful to you. best of luck!

Answer 7

bettas, but there is alot already written about them.

Other species such as arowanas are very interseting to research.
