In recent years, the numbers of the endangered North Atlantic right whales have declined. There are so far 14 famous deaths of these whales. Marine scientists have recently developed a new method to improve the population of these whales.
According to these scientific studies, the number of whales has increased less than three percent every year. The number increased from 270 animals in 1990 to 482 in 2010. Despite this, the percentage of these whales has declined by 99.99 percent since 2010.
Adult females have recorded the biggest decline. They have decreased to a mere 200 whalesin 2010. And they have only further declined to become 186 in 2015. This has lead to the creation of a gap between the number of males and females.
The new statistics provides us with a clearer gesture about the number of North Atlantic right whales. The Current studies and the new statistics proved that the number of these whales has declined since 2010.
The new estimations calculate the number of these whales accurately. These estimations however are not put in consideration most times.
Why was the new statistical model developed?
In the recent years, the North Atlantic right whales changed the place and the time of their past gatherings. This has lead to the decreasing of its sight probability. The North Atlantic right whales that once gathered to feed, and take care of its young recently changed their place of gathering.
This change has lead to makeing the current statistical estimation less credible than the past.leading to the development of a new statistical model to estimate the abundance of these whales.
The Aquarium of New England has conducted searches around the North Atlantic right whales for more than three decades. This Aquarium keeps the data of the whales accurately in a catalog .We depend on these accurate data to estimate the abundance of these whales.
There are a group of researchers who have made annual studies about the North Atlantic right whales. Their studies have been collected in a catalog. These studies are considered a comprehensive enumeration that consists of the photographs of these creatures for the past 25 years.
These researchers managed to photograph the North Atlantic right whales. The total number of these Amazing creatures is 658 whales. Of which 280 of them are females. And the males number at 328. There are also 50 animals of unknown sex.
NOAA Fisheries has issued a warning to fishermen to try and prevent them from crashing into the North Atlantic right whales. Which would lead to more deaths, and injuries in these majestic creatures.
