#HappyEarthDay, celebrate our blue planet that is 70 % water and interlinked with life on land for millions of species and humans! And the vast range of cultures and heritage that humans have created and shaped with interaction with our world's oceans. #coastalhistory

#Fishweirs are one of the primary tools of #indigenouscommunities who populated many of the islands of the #AsiaPacific in #prehistory till recently. Build structures that link human communities and marine life, interacting with each other for 1000s of years. 1/6

#Yap in the #FederatedStatesofMicronesia is home to 800 #aech stone #fishweirs. Fishing of aech was often carried out by multiple families. However, there are several taboos and restrictions which apply to members of the community, including women, excluding them from fishing.2/6

Their construction is not only an anthropogenically derived structure but also the construction of an environment marine species to inhabit and propagate on. Attracting a range of species to be caught but also as an enrichment of the marine ecology of the area. 3/6

The construction of these structures on sandy shores or on reefs of the Pacific islands have an impact on both the ecology of humans and marine species. whether as a form of wave barrier to reduce erosion or as a habitat and haven for marine species to live in! 5/6

Picture of #fishweirs, #IsabelaProvince, #Luzon, #Philippines, from around 1912. The shore has 3/4 large fishweirs jutting out into the waters. Made by Ilocano people, an Austronesian ethnolinguistic group native to the northern coast of Luzon, Philippines.

Examples of maps and ethnographic drawing fishing #Sakhalinisland now in modern #Russia by of the Mamiya Rinzō (間宮 林蔵, 1775 – 13 April 1844) was a #Japanese explorer famous for his exploration of #Karafuto, along coast of the #AmurRiver and the Island of Sakhalin. 1/10 #Artic

Sakhalin (Russian: Сахалин, IPA: [səxɐˈlʲin]) on north coast lies 6.5 km (4.0 mi) off the southeastern coast of Khabarovsk Krai in Russia, while its southern tip lies 40 kilometres (25 mi) north of Japan's Hokkaido. 2/10

The drawing depicts two indigenous fishermen spearing fish, and bundling them up for transport in a sled with dogs in the background. In the foreground of the image two spears lie on what appears to be the side of a riverbank. 3/10

Historically, the island has been inhabited by a mix of different ethnic groups,a mix of indigenous peoples like Ainu, Oroks, and Nivkhs, and others who are now present in tiny numbers, with over 50% of Russians today as part of the modern Russian state. 4/10

During his exploration Mamiya Rinzō, came into contact with many of these indigenous peoples and recorded some of their cultural and activities. The indigenous peoples of Amur River were both fishers and hunters who took advantage of a range of different species. 5/10

A large number of fish types were found in the river/coast, ie lamprey, 2 species of salmon & 2 sturgeon species. Kaluga stur-geon (Huso dauricus), one of the world's largest freshwater fish, is endemic to the Amur-Hei-long River. 6/10

The indigenous peoples of the region employed several fishing methods such as netting, spearing, fish traps and fishweirs along its waterways and on its coastline. Exploiting ecological niches on different species seasonally. 7/10

The #Nivkhs who lived on the lower armour made #fishweirs seasonally along the river and collecting large numbers of fish which they preserved by smoking. Other fisheries that existed were for eels and sturgeon as well as in shore whaling for species of small whales. 8/10

The resources of the region have been heavily depleted since the beginning of the 19th century with some of the rivers being devoid of any viable fish populations. 9/10
