So too have their reproductive rates. Back in the 1980s, scientists recorded births by female North Atlantic Right Whales every three to four years. Fast forward to today, and these same whales are only reproducing having calves every six to ten years. That\u2019s a greatly concerning drop and begs the question: what is preventing the North Atlantic Right Whale from reproducing?<\/p>\n<h3>The Body Keeps Score<\/h3>\n<figure id=\"attachment_5890\" aria-describedby=\"caption-attachment-5890\" style=\"width: 1100px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5890 size-large\" src=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale-1100x784.jpg\" alt=\"north atlantic right whale baby mom\" width=\"1100\" height=\"784\" srcset=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale-1100x784.jpg 1100w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale-640x456.jpg 640w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale-768x547.jpg 768w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale.jpg 1920w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2019\/01\/baby-north-atlantic-right-whale-530x378.jpg 530w\" sizes=\"auto, (max-width: 1100px) 100vw, 1100px\" \/><figcaption id=\"caption-attachment-5890\" class=\"wp-caption-text\">North Atlantic Right Whale mom with baby \u00a9 Getty<\/figcaption><\/figure>\n<p>Any mother will tell you that pregnancy takes everything out of you.

Researchers have documented that approximately 83 per cent of all right whales have been entangled at least once in their lives. Twenty-five per cent face new entanglements each year. Even if a female survives entanglement, her body undergoes such trauma \u2013 fighting for survival while wrapped in heavy fishing gear \u2013 compromising her ability to reproduce in the future.<\/p>\n<h3>A Changing Ocean<\/h3>\n<figure id=\"attachment_15661\" aria-describedby=\"caption-attachment-15661\" style=\"width: 1100px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-15661 size-large\" src=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-1100x734.jpg\" alt=\"\" width=\"1100\" height=\"734\" srcset=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-1100x734.jpg 1100w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-640x427.jpg 640w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-768x512.jpg 768w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-1536x1025.jpg 1536w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776-530x354.jpg 530w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2025\/07\/right-whale-feeding-GettyImages-1295413776.jpg 1920w\" sizes=\"auto, (max-width: 1100px) 100vw, 1100px\" \/><figcaption id=\"caption-attachment-15661\" class=\"wp-caption-text\">Right Whale feeding \u00a9Getty<\/figcaption><\/figure>\n<p>Climate change isn\u2019t just altering weather patterns, it\u2019s also redrawing the ocean\u2019s food web. As ocean temperatures rise and currents shift, the prey North Atlantic Right Whales depend on are either moving to different areas of the ocean or becoming scarce. And it\u2019s not just happening to the North Atlantic Right Whale! Researchers have noted that both Humpback and Blue Whales have had to migrate much further to reach feeding grounds, leaving them with less time to feast and build up the body fat they need. For North Atlantic Right Whales, this adds yet another obstacle to the species\u2019 survival. If a female isn\u2019t in peak physical condition, how can we expect her body to support the demands of pregnancy and nursing? And without new young, how in the world will this important species bounce back from the brink of extinction?<\/p>\n<h3>How Can You Help Whales?<\/h3>\n<figure id=\"attachment_3061\" aria-describedby=\"caption-attachment-3061\" style=\"width: 640px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3061 size-medium\" src=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale-640x360.jpg\" alt=\"North Atlantic Right Whale\" width=\"640\" height=\"360\" srcset=\"https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale-640x360.jpg 640w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale-768x432.jpg 768w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale-1100x619.jpg 1100w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale-530x298.jpg 530w, https:\/\/blog.cwf-fcf.org\/wp-content\/uploads\/2016\/12\/right-whale.jpg 1152w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption id=\"caption-attachment-3061\" class=\"wp-caption-text\">Right Whale breaching<\/figcaption><\/figure>\n<ul>\n<li><strong>Don\u2019t<\/strong> use single use plastics.
