“…Thus, generally and ecologically, the species of fish found in the Mahakam River, especially around Tanjung Una comprises two groups, group of river fish and group of marine fish. The fish is same with the fish caught in the mouth of the Mahakam delta at salinity of 1.3 to 33.0‰ (Suyatna et al 2010). In addition, Juliani and Suyatna (2014) found the species in the coastal waters of Sangatta in salinity of 20.2 to 33.0‰.…”

Abstract. Suyatna, I, Mislan. A. Rahman A. Winta Wijaya YI. 2017 Kartanegara,. The aim of this study is to dig up more information about the biophysical conditions of Mahakam River around Tanjung Una of Kutai Kartanegara, Indonesia including the fishery potential in these locations. The observations were conducted in two periods. Through field surveys, the sample of fish and shrimp were caught with pulled nets from many stations, while to know the water quality around the location of the observation, water sampling was conducted and then the sample was brought to a laboratory to be analyzed in order to find out its quality. On the scale of taxonomy and ecology, community structure of fish and shrimp from 21 species of fish consisted of 17 families, five orders, and one class. For the shrimp, it was only four identified species of the genus Macrobrachium family Palaemonidae and genus Metapenaeus family Penaeidae ordo Decapoda class Malacostraca. The distribution of the length and weight of fish and shrimp was found out to be small. The value of the diversity index between the fish and shrimp showed low to moderate with a value of D: 0.150 to 0.601; H': from 0.986 to 2.089, E: 0.268 to 0.621 and Margalef: 1,475-2,345 for the fish and a value of D: 0.325 to 0.688, H': from 0.615 to 1.205, E: 0.462 to 0.834 and Margalef: from 0.490 to 0.614 for the shrimp. The index indicated that there were species that tend to dominate other species. The species richness was low. Physical-chemical properties and heavy metal content in the Mahakam River around Tanjung Una were generally still below the quality standard. The observations concluded that the number of marine fish species was found two times higher than the river fish species, but not to the number of population. .

“…While from 29 fish species observed in the middle part of Mahakam, only one species was commonly living in marine area, Lampa-lampa or Bilis (Bareback anchovy, Papuaengraulis micropinna). All marine fish species found both in the lower and middle part of Mahakam was known to distribute along coastal and sea waters of Makassar strait from southern to northern of Panajam Paser Utara district (Bappeda and Fpik Unmul, 2017), Kutai Kartanegara district (Suyatna et al, 2010), Bontang city (Suyatna et al, 2016) and Sangatta Utara district (Juliani and Suyatna, 2014). Both marine and freshwater fish species in the lower part of Mahakam was also reported in the result of a biophysical observation of Mahakam river (Suyatna et al, 2017).…”

A first survey on a community marine species in river of Mahakam East Kalimantan was performed in December 2015 and May 2016. Fish samplings were carried out from two locations the lower and the middle part of Mahakam. Whilst hydrometric observation of current velocity, water depth and tide was measured not only at the locations but also along the river from 2013 to 2017, tide was only observed in the lower part of Mahakam. However, marine fish species were recognized to reach up the middle part of Mahakam, 230 km from coastline. To describe a community fish structure and its dissimilarity of the two surveyed locations, diversity and bray Curtis index were applied. Almost 15 marine fish species identified in river of Mahakam was demersal fish and index of the similarity of marine fish community between the locations only 0.106.

“…In India, pugnose ponyfish (Secutor sp) is one of the major by-catch composition (Muddula 2015) from the country leiognathids were known 16 species (Abraham et al 2011), in Sri Lanka 13 species , in Malaysia 22 species (Seah et al 2011) that were identified from eight or nine genera (Seah et al 2012), at certain location of Malaysia such as the coastal waters of Pulau Sibu-Tinggi nine species (Mazlan et al 2006), and in Thailand found in intertidal mudflats seven species (Sichum and Tantichodok 2013). In Indonesia, these fishes from various places were reported 11 species (Suyatna et al 2010), 10 species (Wedjatmiko 2007), 20 species (Pauly 1977.

Abstract. Suyatna I, Sidik AS, Almadi FA, Rizal S, Sukarti K. 2016. Fish community structure in high water temperature around Bontang Industrial Estate, East Kalimantan, Indonesia. Biodiversitas 17: 558-564. We have conducted studies on fish community and their physical and chemical properties of coastal waters in the work area of the industrial estate from 2012 to 2014. At least four industries are known to use the coastal waters in cooling their processing equipments, the hot wastewater is then discharged back into the coastal environment. The current study reports the result of a survey undertaken around the work area of PT Blackbear Resources Indonesia. The result showed that high water temperature and tidal fluctuation are affecting the fish community in the area. By sampling results, during HWL of the spring tide at the maximum of water temperature of 35,9 o C, fish were the most populated and found 5999 ind. or 72,4% of the total number of 8291 fish. During LWL of the same tide type fish were observed 1931 ind (23.3%) and during the neap tide 361 ind (4.3%) at the maximum of water temperature of approximately 40 o C, this ambient showed that the fish population drastically change in number and the environment became undesirable.
