Parentage Analysis Reveals Unequal Family Sizes during Hatchery Production

چکیده

Lake sturgeon (Acipenser fulvescens) is a species of conservation concern that has been stocked in several Great Lakes (North America) rivers. were extirpated the Ontonagon River Superior and stocking began 1998. In 2017, gametes collected from spawning lake (9 females, 36 males) caught at nearby Sturgeon ground, generating nine family groups using 1:4 mating design (n = 862). 2018, 3 females 15 males, three groups, additional collections drifting fry reared hatchery, resulting 84 hatchery-produced 675 wild-caught for River. The objective this study was to compare paternal representation genetic diversity between two strategies. Parentage analysis based on data 12 microsatellite loci determined none hatchery had equal (p < 0.001), while wild-produced offspring representation. Despite larger number breeders contributing larvae, there no significant difference larvae representative offspring.

Test for Intraclass Correlation Coefficient under Unequal Family Sizes

Three tests are proposed based on F-distribution, Likelihood Ratio Test (LRT) and large sample Z-test for intraclass correlation coefficient under unequal family sizes based on a single multinormal sample. It has been found that the test based on F-distribution consistently and reliably produces results superior to those of Likelihood Ratio Test (LRT) and large sample Z-test in terms of size fo...

On testing equality of intraclass correlations under unequal family sizes

The three likelihood-based tests, namely, likelihood ratio test, Rao score test, and Wald test and two more asymptotic tests which use Srivastava’s estimator of intraclass correlation coefficient are considered to test the null hypothesis of equality of intraclass correlation coefficients when the families have unequal number of children. Methods are illustrated on Galton’s data set. Using simu...

Centralized Caching with Unequal Cache Sizes

We address centralized caching problem with unequal cache sizes. We consider a system with a server of files connected through a shared error-free link to a group of cacheenabled users where one subgroup has a larger cache size than the rest. We investigate caching schemes with uncoded cache placement which minimize the load of worst-case demands over the shared link. We propose a caching schem...

Production of tropical oyster seed in hatchery

Oysters have been collected from wild since long time ago for human consumption. Recent development in aquaculture has allows the production of its seed in hatchery. Factors favoring the oyster production are stocking density, water quality and the availability of live food. These factors can increase the growth and survival of the oyster. Fundamental knowledge on life cycle and biology of oyst...
