    Default What lake come from Sulawesi shrimps ?

    As I know, there are several lakes in Sulawesi. Biggest should be Malili lake system with pH approx. 8. Second one is lake Poso with water pH +-7.
    Correct me, if am I wrong.
    What I never found is origin of imported shrimps?
    Where they come from? Malili? Poso? both? which species from where?
    What about Cardinals and Spongicolas?
    Does someone know?

    Really Malili is not a lake, it is a lakes system. it is compound for Matano lake that flows to Mahalona lake, and this flows to Towuti lake, tree ones are relatively good connected. There are also to satellite lakes Lontoa and Matano, they are so little.

    Poso is not realted with Malili lakes system, it is in the north of the island, and it has special features as termocline in their water -a sort of temperature stratification-.

    Most of the new species are from Malili lakes system. Spongicola comes from Towuti lake, and Cardinal comes from Matano lake.

    This is all I know about.

    Is it possible for anyone to go and see this place? That would be so awesome to see wild Sulawesi shrimps! I bet they're gorgeous in their natural habitat.

    Lake Matano (Indonesian: Danau Matano)

    As mentioned, Lake Matano is the northernmost lake of the Malili lake system. It has a maximum depth of 590m, making it the tenth deepest lake in the world. At 164.1km², its surface area is less than that of Lake Towuti, however.

    The water parameters in the shallows of Lake Matano are as follows:
    Temperature (°C) 28.7
    pH 8.5
    General hardness (°GH) 7
    Carbonate hardness (°KH) 5
    Conductance (μS) 175
    Total dissolved solids (ppm) 87.5
    Oxygen (mg/l) 6.93

    The following shrimp species can be found within the lake:

    Caridina dennerli
    Caridina holthuisi
    Caridina lanceolata
    Caridina loehae
    Caridina mahalona
    Caridina masapi
    Caridina parvula

    Petea River

    The Petea River connects Lake Matano to Lake Mahalona. Shrimp that are found within the river are not thus considered riverine, as it is considered an extension of either lake rather than a true river.

    The following shrimp species can be found within the river:

    Caridina holthuisi
    Caridina lanceolata
    Caridina loehae
    Caridina masapi
    Caridina parvula

    Lake Mahalona (Indonesian: Danau Mahalona)

    Lake Mahalona is south-east of Lake Matano and north of Lake Towuti. It is far smaller than the two, with a meximum depth of 73m. This lake is connected to Lake Matano and Lake Towuti by the Petea River and Tominanga River respectively.

    The following shrimp species can be found within the lake:

    Caridina holthuisi
    Caridina lanceolata
    Caridina lingkonae
    Caridina masapi
    Caridina striata
    Caridina tenuirostris

    Tominanga River

    The Tominanga River connects Lake Mahalona to Lake Towuti. Shrimp that are found within the river are not thus considered riverine, as it is considered an extension of either lake rather than a true river.

    The following shrimp species can be found within the river:

    Caridina lanceolata
    Caridina masapi
    Caridina parvula
    Caridina tenuirostris

    Lake Towuti (Indonesian: Danau Touti)

    With a maximum depth of 203m, Lake Towuti is dramatically shallower than Lake Matano. Despite this, Lake Towuti has the greatest volume of all the Malili lakes. This is due to its large surface area of 561.1km².

    The water parameters in the shallows of Lake Towuti are as follows:
    Temperature (°C) 29.2
    pH 8.4
    General hardness (°GH) 6
    Carbonate hardness (°KH) 4
    Conductance (μS) 146
    Total dissolved solids (ppm) 73
    Oxygen (mg/l) 7.15

    The following shrimp species can be found within the lake:

    Caridina glaubrechti
    Caridina holthuisi
    Caridina lanceolata
    Caridina lingkonae
    Caridina loehae
    Caridina masapi
    Caridina parvula
    Caridina profundicola
    Caridina spinata
    Caridina spongicola
    Caridina striata
    Caridina tenuirostris
    Caridina woltereckae

    Larona River

    The Larona River is to the west of Lake Towuti and drains the Malili lake system via Towuti Outlet Bay. Shrimp that are found within the river are not necessarily thus considered riverine, as it may considered an extension of Lake Towuti.

    The following shrimp species can be found within the river:

    Caridina lanceolata
    Caridina masapi
    Caridina tenuirostris

    Lake Lontoa (Indonesian: Danau Lontoa)

    Lake Lontoa is a satellite lake within the Malili lake system, and has a maximum depth of 2-4m.

    The following shrimp species can be found within the lake:

    Caridina masapi

    Lake Masapi (Indonesian: Danau Masapi)

    Lake Masapi is a satellite lake within the Malili lake system, and has a maximum depth of 2-4m.

    The following shrimp species can be found within the lake:

    Caridina masapi

    General rivers, not considered extensions of lakes

    These are the rivers that are not considered extensions of the lakes within the Malili lake system, and shrimp found within them are considered riverine.

    The following shrimp species can be found within the rivers:

    Caridina mahalona
    Caridina masapi
