The twaite shad (Alosa fallax), a herring family member, was once abundant in British rivers, with thousands of fish spawning upstream in the spring.
Overfishing, deforestation, habitat loss, and migratory path obstruction have all contributed to population declines. Hybridization between species is more common in species that have been disturbed by humans. The estuarine period, or the time they spend in estuaries swimming from spawning grounds to sea, is expected to last up to a year and a half in A. fallax. Specific heterogeneity and juvenile survival in the estuarine phase are not taken into consideration in the calculation.

The aquaculture industry should concentrate on cultivating simpler species with less welfare and environmental threats, such as seaweeds and bivalves like oysters, mussels, and clams.
According to Franks, intelligent creatures such as octopus should not be farmed at all.
Over the last few decades, the global aquaculture industry has risen to a size of $250 billion (£182 billion). Aquaculture has been criticized for detrimental effects such as deforestation, reliance on wild fish for feed, and overuse of antibiotics. It was described as a response to the exploitation of wild fish stocks.
According to the report, health should be taken into account as well. Fish have long-term memory, can solve challenges, work with other animals, and sense discomfort, contrary to popular opinion. Octopuses and other cephalopods can solve puzzles, traverse mazes, and open jars. Crayfish display emotional behavior, such as fear and tension, and spiny lobsters have advanced navigati

The Australian government has formally recognized the loss of 13 endemic species, including 12 mammals and the first reptile to be lost since European colonization.
The dozen mammal species addition solidifies Australia s unenviable status as the world s mammal extinction capital, bringing the cumulative number of mammals believed to have died out to 34.
Inevitable
None of the 13 was unexpected. Except for one, all of the mammal extinctions are recent, with the majority occurring between the 1850s and 1950s.
However, the record contains two animals that have been extinct in the last decade, both from the Indian Ocean s Christmas Island.
According to The Guardian Australia, the last Christmas Island pipistrelle, a bat genus, died in 2009. In 2014, the last living Christmas Island forest skink - the first Australian reptile to go extinct - was discovered. The International Union for Conservation of Nature has historically recorded all extinctions (IUCN)
