Good Dutch rare fish news


This video is called Brook Lamprey Spawning April 2011.

Translated from the Dutch water management organisation De Dommel, about saving fish before dredging the river Dommel at the Klotputten sand catchment spot:

Tuesday, December 11, 2012

As a precaution, the water, in addition to the exemption rules, was thoroughly inspected for the presence of brook lampreys. During these checks a hundred brook lampreys were captured. These lampreys were transferred a few kilometers south of the Klotputten to a suitable habitat. This capture shows that the brook lamprey population in this part of the Dommel is much larger than we previously thought. During this activity also a large number of individuals of the protected spined loach, some gudgeons and some perches were captured.

Ecological development

Lately, we see a tremendous positive environmental development in the upper Dommel river. For example, last year the very rare green gomphid dragonfly and the common club-tail dragonfly were found. These species, like the brook lamprey, depend on clean water and good morphological processes.

This is a video of brook lampreys sharing a spawning ground with river lampreys, a larger related species. As far as is known, the first ever observation of this in the Netherlands.

 

Tajikistan snow leopards, video

Snow leopard cubs – A video from Tajikistan

Snow leopards thriving in Tajikistan

December 2012. Known as the ‘Roof of the World,’ the Pamir Mountains of Tajikistan are situated at the intersection of several of Asia’s greatest mountain ranges, and fittingly may represent some of the richest habitat for ‘Asia’s Mountain Ghost’ – the elusive snow leopard.

300 snow leopards in the Pamirs

Today, as many as 300 of the remaining 3,500-7,000 wild snow leopards are thought to live in the Tajik Pamirs – an area which provides a potentially critical link between the southern and northern regions of the snow leopard’s range, and may serve as a vital genetic corridor for the species.

Given the potential of this region as one of the world’s last snow leopard strongholds, big cat charity Panthera recently carried out two extensive camera trap surveys in the Pamir Mountains, including one in Tajikistan’s Jartygumbez Istyk River region in collaboration with University of Delaware graduate student Shannon Kachel and the Tajik Academy of Sciences.

While reviewing photos from the survey’s 40 camera traps, Panthera field staff recently uncovered incredible new images of a snow leopard mother and her two cubs, which they have made into a video. The playful cubs are shown licking and pawing icicles and attempting to climb a rock. Along with this entertaining footage, also included are stunning images of the snow leopard mother and one of her cubs inspecting the camera trap, their quizzical faces pressed up against the camera lens.

Healthy population?

In addition to this special glimpse into the hidden lives of snow leopards, this footage also potentially indicates that a healthy, breeding snow leopard population exists in the Jartygumbez Istyk River region of Tajikistan, within a well-managed trophy hunting concession. These data are particularly positive for the region’s snow leopard population when paired with evidence gathered in the summer of 2011 of snow leopard cubs (stealing a camera trap) in the Zorkul region of Tajikistan’s Pamir Mountains (a collaborative project with Fauna and Flora International), approximately 100 km south of the Jartygumbez Istyk River region.

Scat analysis

Panthera scientists are reviewing all of the camera trap photos from the surveys to assess the size of the region’s snow leopard population and the significance of the Pamirs as a part of the snow leopard’s corridor. In addition, Panthera’s field staff and partners have collected snow leopard scat samples for diet analysis, are conducting surveys to evaluate the abundance of snow leopard prey species and are also assessing the management and impact of local trophy hunting concessions and nature reserves, which target snow leopard prey species.

Poaching and unsustainable hunting of snow leopard prey

Panthera’s scientists have identified poaching and unsustainable hunting of snow leopard prey, including ibex and Marco polo sheep, as a major threat to Tajikistan’s snow leopards. To address this issue, our field staff are working with local villagers and a trophy “prey” hunting expert to analyze the infrastructure and training needed to establish a community-based hunting program of prey species.

Community based programme

Scheduled to begin in 2013, this program aims to better regulate the current unsustainable hunting of ibex and Marco polo sheep to conserve Tajikistan’s snow leopards, while bringing direct economic benefits to local villagers through tourism operations. Ultimately, if successful, Panthera hopes to use this community-based prey hunting program model to implement similar operations in other Central Asian countries.

Dutch nature reserve water animals


This video is about the Slufter area on Texel.

In nature reserve De Slufter on Texel island in the Netherlands, warden Dick Schermer has investigated animals of brackish water.

In Achtbunder creek, there is hardly any sea water; mainly fresh water.

There, especially ostracods (in August) and water boatmen live.

However, in the Madura creek, salt water flows in regularly. There, common gobies, chameleon shrimps, Palaemonetes varians shrimps, etc. live.
