Also check for the individual dry weight of Artemia during the development from cysts to newly hatched nauplii in our 1998 paper from Aquaculture (also in the profile). Do you have any photo of Atherina boyeri egg?

Does anyone know the daily ingestion rate of Artemia in percid larvae from the day they start feeding to weaning on day 16 after hatching? It's pretty common in elasmobranchs. Yes Azad sir truly said....but the results are varying and no conclusive outcome can be drawn based on a species. Is there an idea, opinion, suggestion or sound knowledge about promising feedstuffs of plant or animal origin to be used as partial alternatives for example in common carp feeds? Check this book. Actually I have data with distances between a target fish and three prey (quantitative dependent variable) in function of time (quantitative  input also) and I found that it is called a time serie. To what level will the pH decrease? I have a historical collection of otoliths mounted in both 1,2-dichloroethane and cytoseal which I'd like to remove for detailed shape analysis. Is Ariosoma granadosi, Talwar and Mukherjee 1977, is a valid species. Our focus is on morphological characteristics, nutritional and reproductive physiology, metabolism, respiration and bioenergetics, biochemistry and molecular mechanisms as well as behavior. I don't think the goal was to measure speed, more about behavior and reaction time, but the methods might give you some ideas. We found that a significant bioaccumulation of Cu while the Cu concentration in water was not detectable (<0.001 ppb). Can anyone tell me the mechanism for micronucleus formation in fish blood cells? Please check your email for instructions on resetting your password. Has anyone a photo of caudal skeleton in Oncorhyncus or a paper with its detailed description? Thus, try first with one brain and evaluate the results.

I looked in the suggested papers and couldn't find what I am looking. Some uses cumulative percentage of all samples of fully matured egg (Stage v and above) to estimate Lm. doi:10.1111/j.0022-1112.2006.00940.x, Jerison, H. J.

As far as I know, there is (neither theoretical or practical ) no PCR enzyme which can carry out all the amplification you desire. You apparently have quite a heat tolerant strain of rainbow, as most studies report critical tolerance limits for rainbow trout to be 24-26 C. Although the fish may be able to survive, the near-lethal temperatures have extremely negative impact on the physiology of the fish. 2, pp.

Do you have any record of the tropical fish Gymnarchus niloticus breeding in captivity? Source Normalized Impact per Paper (SNIP).

Dear Syed, thank you very much for the information. my bamboo sharks are far from photogenic and won't stay still long enough for me to get anything more than a very blurred mess. Cookies are used by this site.
I know for humans it is argued not to be, but is it potentially useful in providing fish or zooplankton, with usable b12 supplement. To be more precise, I look for the Arctic char quantities of N and P inside their body. There is a vast literature on this subject, including several textbooks. https://www3.epa.gov/region1/npdes/merrimackstation/pdfs/ar/AR-1242.pdf. Fish meal is a limited source and there's only so much plant material you can add to the feed of carnivorous fish species as salmon.
