Sea Turtle Conservation

CONSERVATION OF SEA TURTLE, NEST AND HABITAT

In season 2018-19, we have recorded 755 olive ridley nests and 7 Green turtle nests along the entire Bangladesh coast except the Mangrove Sunderban. Out of that 755 nests have been recorded and conserved within FWS-US project area. A total 65,388 hatchlings so far been released by the community people that hatched MLA sea turtle program, estimated more than 76% hatching on average. In few cases highest 98 % hatching also recorded by the local people within the semi in situ relocated hatching ground. The nest record and the hatchlings release increased dramatically comparing the previous year efforts. It seems that due to the lack of survey efforts before, we could not get all nesting information. 100% in situ conservation is virtually ineffective in Bangladesh coast specially in Cox’s Bazar area until now, but our current effort on hatching success is good comparing other projects in other country. Here relocation hatching ground summarized in the following Table-4.1. Few nests face inundation in late season and pre-monsoon period in May–June. The nest record and hatchlings release increased dramatically comparing seasons before 2013, as large number of manpower recruited for nest monitoring and conservation through the integrated efforts of BFD, FWS. It seems that due to lack of survey efforts before, we could not get all nesting information and many nests might have been stolen, predated or some might have been naturally hatched without any records. Currently largely in situ conservation is virtually ineffective in Bangladesh coast specially in Cox’s Bazar area until now due to large number of settlements and disturbances. Although relocation is discouraged throughout the world, in Bangladesh it is still our destiny and Marinelife Alliance found out innovative hatching technique just using natural parameters. Nesting and hatching data summery has been depicted in the Figure-5.14a and 5.9. We have done a comprehensive work on education and awareness program around 300 fishing boats have so far been registered and fishermen’s are periodically being trained and motivated on bycatch reduction, data collection and try to help safe release of marine megafauna affected in bycatch.

AWARENESS AND EDUCATION

Awareness programs and local school education programs done to share knowledge with the grassroots people like general inhabitants, local elites, fishermen about the facts of sea turtle. Videos exhibited to the people, target groups to influence positively.

SEA TURTLE MIGRATION STUDY 💦 Figure-9.13. PIT tagging on juvenile hawksbill turtle at Sonadia Island: turtle scanning with BioMark PIT tag scanner, (left) and PIT microchips, Scanner and PIT Tag applicator. 9.6. SATELLITE TRACKING Figure-8.7. Satellite tracking system illustrations (top); map showing satellite tagging locations along Cox’s Bazar coast (above); two types of satellite tag used in program SPLASH10-309A and SPOT-293A (below). Satellite tracking conducted to study migration and foraging habitat of sea turtle nest along Bangladesh coast. Satellite tracking involves attaching on the sea turtle shell a Platform Terminal Transmitter (PTT) and getting the transmission data from ARGOS satellite. The PTT send message to satellite each time the turtle comes to the surface to breathe and the analyzed location data of the tracked turtle then sent to MLA researcher via ARGOS satellite. In...

Plankton

What is plankton? Plankton are marine drifters — organisms carried along by tides and currents Phytoplankton blooms in the Barents Sea, shown in natural color from NASA's Aqua satellite on July 10, 2014. The solid white area in the top right corner is cloud cover. Credit: NASA's Earth Observatory The word “plankton” comes from the Greek for “drifter” or “wanderer.” An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces. Some plankton drift this way for their entire life cycle. Others are only classified as plankton when they are young, but they eventually grow large enough to swim against the currents. Plankton are usually microscopic, often less than one inch in length, but they also include larger species like some crustaceans and jellyfish. Scientists classify plankton in several ways, including by size, type, and how long they spend drifting. But t...

Shark Finning

The Massacre of the World's Sharks for Soup BY EDWARD DORSON The world's sharks are quickly vanishing and it's primarily driven by the demand for shark fins as an ingredient of a status symbol soup devoured throughout Asia at weddings and banquets. Approximately 73 to 100 million sharks are killed annually worldwide just for their fins. Some shark populations are already functionally extinct, having declined by as much as 99%. The outcome of further inaction will soon create a vast jellyfish soup, formally known as the ocean. Sharks targeted by finners aren't taken whole; their valuable fins (up to $700 a kilo, at the time of this writing) are sliced off and the living mutilated shark is tossed back into the sea to sink and slowly die. It is despicably inhumane. The obliteration of 400 million years of evolution for some perceived social status with serving shark fin soup isn't just idiotic and cruel - it's tragic. A healthy ocean depends on sharks. Scientific...
