164 TREUBIA VOL. IJ, 2—4. 
VAN BREEN (7°) in his schedule of the owners, areas and assessed 
values (for ground-tax purposes) (verpondingswaarde) of the territories oc- 
cupied by the fish-ponds north of the capital town of Batavia, between the 
Muara Angke and the Kali Sunter, computes the total area at 1100 hectares 
- or 2720 acres. This fits well with the calculation of the Cadastral Survey 
Office above referred to, according to which the area would be 1195 hectares 
or 2950 acres, as stated above. | 
Outside this principal zone of marine fish-ponds there is another small 
group of sea fish-ponds in the neighbourhood of Batavia, west of the 
Muara Angke, which, inclusive of the intermediate embankments and 
walls, covers an area of 33 hectares or about 80 acres. Still further west 
we get to the marine ponds laid out only a few years ago near Kamal, 
measuring inclusive of embankments and walls circa 55 hectares or 135 acres. 
East of Tandjong Priok there is finally a group of marine fish-ponds, . 
originally extending from just east of the first old western harbour-dock of 
Tandjong Priok as far as Marunda, just east of the Muara Tjilintjing. Of 
late years, however, the empangs in a large part of the western end of 
this pond-district have disappeared in connection with the expansion of 
the harbour towards the East. On the other hand I was informed by 
people hailing from those parts, that during the last 5(?) years the entire 
littoral zone from Marunda to the East as far as Sungei Tawar has 
been occupied by newly laid out sea-fish-ponds. 
The old fish-pond district between Tandjong Priok and Marunda, with 
which I am personally familiar, at present ') extends from Pedjonkoran, 
situated about 2!/, K.M. east of the first old western harbour-basin of 
Tandjong Priok, as far as Marunda, and, according to the Cadastral Survey 
Office, it covers an area of some 840 hectares or 2075 acres. Within this 
territory the fish-ponds together with the intermediate embankments and 
earthen walls occupy 296 hectares or 730 acres according to the Cadastral 
Survey Office, my own calculation yielding 285 hectares or 704 acres. 
The abovementioned ponds, not known to me from personal inspection 
and situated between Maıunda and Sungei Tawar, do not figure in any 
map. The Kamal fish-ponds are represented only on the latest Topograph- 
ical Service map. As for the remaining marine fish-ponds in the Residency 
of Batavia, the Topographical Service maps only show the following additional 
ones: near Tandjong Kait (in the Tangerang region); near Gagah (near 
the Hook of Krawang) and near Pakis (at the western boundary of the 
District (Afdeeling) of Krawang). From fishermen coming from those 
beaches | learned however, that in the course of the last few years new 
fish-ponds have been laid out along the Muara Tangerang, facing the 
isle of Onrust, and along a considerable part of the coast of the 
District (Afdeeling) of Meester Cornelis, near Muara Gembong, Gagah, 
Blubuk and Muara Bungin.
