P. har­veyi lat­est devel­op­ment


For each species we now start a con­tin­ual doc­u­men­ta­tion of the infor­ma­tion which is gath­ered over time. This we have decided to do because it is becom­ing increas­ingly clear, that the devel­op­ment and changes in the nat­ural habi­tats, and in the occur­ance of the species are hap­pen­ing rapidly. We find it impor­tant that we doc­u­ment as much infor­ma­tion as pos­si­ble in order to estab­lish a rel­a­tive clear pic­ture of what is happening.

The resources of infor­ma­tions are many and var­ied, so infor­ma­tion often becomes spread around on the inter­net and is not col­lected in one place. These infor­ma­tions can come from reports from the local areas, of local experts who observe changes hap­pen­ing, from pri­vate col­lec­tors and local enthu­si­asts who posts on face­book, or it can come from arti­cles, sci­en­tific stud­ies in the fields and many oth­ers. It is there­fore not just one coher­ent report we attempt to make but rather a gath­er­ing of many sources of infor­ma­tion, with the excact men­tion of dates and source of infor­ma­tion. We will how­ever, often not men­tion spe­cific loca­tions pre­cisely, as we wish to pro­tect these as much as possible.

We hope to con­tribute this way to the con­tin­ual increase of under­stand­ing and knowl­edge of the extreme threa­thened sit­u­a­tion of the parosphroe­menus species.


Dis­tri­b­u­tion area

West Malaysia, type local­ity Batu Arang. This wet­land is now largely destroyed. The species still exists in suit­able rem­nants of marshes of the for­merly large jun­gle of Selan­gor (100 km north of Batu Arang)

No fur­ther occurences are known.

Threaths P. har­veyi

Very high.

After the type local­ity has been dried up almost com­pletely, de-​forested and thus made barely inhab­it­able for licourice gouramies, the species appear to have adjourned into the for­merly extended nature pro­tec­tion area ‘Selan­gor For­est’. But despite its pro­tected sta­tus this area too has been drained in large parts and has been trans­formed into plan­ta­tions. P har­veyi tries to sur­vive in some of the drainage canals and in reamin­ing black water swamps of the relict jungle.


In 2018 the Parosphromenus Project was con­tacted by Aidil Mohd Shameen, who wished to con­tribute to our work by mon­i­tor­ing the par­tic­u­lar area of ‘Selan­gog For­est’ and keep us informed.

Aidil Mohd Shameen lives in this area, and is one of the local experts of the nat­ural habi­tats of not only parosphromenus species, but many other Malaysian native species.

We will upload infor­ma­tion here, as we get it, — and it serves as a quiet and citizen-​science approach, highly impor­tant way of keep­ing in touch with this par­tic­u­lar area.

Novem­ber 2018: Report­ing a total of 18 spec­i­ments catch over one day, most juve­niles. The con­di­tions of the peat swamp sta­ble, yet with oil­spills. No sign of defor­esta­tion or dis­tur­bance of the swamps

Decem­ber 2018: 4th decem­ber 2018, on another pop­u­la­tion sur­vey of the p.harveyi habi­tat. A total of 28 spec­i­ments was found. 9 con­firm males, 13 con­firm females and 6 juve­niles. Other fish include 37 spec­i­ments of betta livida and 6 choco­late gourami along with other barbs and ras­b­o­ras. There are sign of oil spill on the sur­face of the water from road construction..The for­est is still ok with no sign of deforestation.
