As fry, this species feeds on zooplankton in the river and is known to be cannibalistic. After approximately one year, the fish becomes herbivorous, feeding on filamentous algae, probably ingesting larvae and periphyton accidentally.
Due Date Calculator. This interactive Due Date Calculator will help you estimate the date your baby will arrive. Pregnancy usually lasts 280 days (40 weeks) from the first day of the woman's last menstrual period. This calculator is a general guide: every pregnancy is unique, and sometimes babies arrive sooner or later than expected. Always talk to your health care provider about your due date. Once you're pregnant, be sure to have regular checkups by a doctor, certified nurse-midwife or other health care professional during the course of your pregnancy.
To calculate the number of weeks you are, you simply start with the first day of your last menstrual period, also called LMP. So if the first day of your last period was January 1st, your first week of pregnancy is January 1-7th, though you are one week pregnant on January 7th as you complete the week. January 8-14th would be the second week, two weeks pregnant on January 14th. Your doctor or midwife may even count days. So for example, if you were, using the January 1st date, five weeks three days pregnant would be February 7th. If you were doing an early ultrasound to look for a heartbeat, you may not see much of anything, but wait a week, until after six weeks, around February 15th, and you would see a lot more.
