Summary of "Population structure of the monogenean, Paramazocraes thrissocles (Mazocraeidae) on the gills of clupeoid fish, Thryssa mystax of Visakhapatnam coast, Bay of Bengal."

An investigation was undertaken on the population biology of the mazocraeid monogenean Paramazocreas thrissocles occurring on the gills of the engraulid fish Thryssa mystax at Visakhapatnam coast , Bay of Bengal. The influence of season and host size on the parasite population density and the dispersion pattern of the parasite in the host population were analysed. A distinct seasonal pattern in the prevalence and intensity to infection is noted with higher parasite loads prevailing during warmer summer months and very low or no infection during winter months. The heavy infections are found to be promoted by high temperatures prevailing during summer months coupled with high host density and the larger size of fish examined during this period. A positive correlation between host size and prevalence and mean intensity to infection with the monogenean was noted, larger fish often carrying heavy infections. Further the monogenean showed an aggregated distribution on the host population as evidenced by the low value of negative binomial parameter 'K'.

Medical and Biotech [MESH] Definitions

Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.

Statistical interpretation and description of a population with reference to distribution, composition, or structure.

The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.

Morphological or behavioral traits influenced by various living conditions that a population encounters especially as it pertains to REPRODUCTION and survival of the population (see POPULATION DYNAMICS) such as age at first reproductive event, number and size of offspring, and lifespan.

Monitoring of rate of occurrence of specific conditions to assess the stability or change in health levels of a population. It is also the study of disease rates in a specific cohort, geographic area, population subgroup, etc. to estimate trends in larger population. (From Last, Dictionary of Epidemiology, 2d ed)
