This research aimed to determine the species composition of fishes in the Kaliotik River, Lamongan Regency. The sampling was conducted from March to May 2020 at four stations. A total of 1031 samples caught by the fishing net during the study consists of Anabas testudineus, Trichogaster trichopterus, Hyposarcus pardalis, Mystus sp., Channa striata, Oreochromis mossambicus. The fish diversity index values indicated that the river is in low to moderate condition. The species was also slightly evenly distributed in the waters with no dominant species. Trichogaster sp. and Anabas testudineus are the two dominant species found in the waters with a relative abundance of 44 % and 41 %, respectively. The Kaliotik River ecosystem balance was affected by disposal from human activities along the riverbank.

The diversity of freshwater fishes which inhabit in the river of Daerah Istimewa Yogyakarta is not yet well documented. Complete documentation is needed as starting point and continuous research on the fish diversity in DIY. Boyong-Code River flows across the DIY, and it upstream is located on the hillside of Merapi volcano. The Code River upstream is called Boyong River. The research was aimed to acquire data about the diversity of fish fauna along the Boyong-Code River in the DIY. Further, the research purpose is to know which species are rare, potential for aquaculture, and introductive. Samples are taken along the Boyong-Code River starting from upstream to downstream. Samples were collected using Purposive Random Sampling methods with fishnets. Sampling area generally divided into three location i.e., upstream, middle-stream and downstream. Species diversity of fish in the Boyong-Code River is consisted of 24 species, with 5 introductive species. There are eleven native fish species which are potential for cultivation (aquaculture), i.e.: Barbodes binotatus, Mystacoleucus obtusirostris, Rasbora lateristriata, Rasbora argyrotaenia, Barbonymus balleroides, Osteochilus vittatus, Hampala macrolepidota, Anabas testudineus, Channa striata, Clarias leiacanthus and Clarias batrachus. The Boyong-Code River is a decent habitat for fishes. Many introduced fishes starting to invade the Boyong-Code River intentionally or unintentionally by human

Fish Species Composition

Estuaries are critical aquatic environments that are used by many fish during their life cycle. However, estuaries often suffer from poor water quality as a result of anthropogenic activities. Fish diversity studies in estuaries are common, although few have examined whether correlations exist between water quality, metal contamination and fish assemblages. In the present study we investigated the effect of abiotic conditions, heavy metals and estuary characteristics on the abundance, diversity and composition of fish in four intermittently open estuaries along the Illawarra coast of south-eastern Australia. The heterogeneity of environmental conditions was reflected in the fish assemblages in each estuary. Environmental variables predicted fish species composition, and estuaries in particularly poor condition contained few species (estuarine residents) in high abundance, indicating their ability to acclimatise and survive in conditions that are hostile to other species. Overall, these findings demonstrate that estuarine fish assemblages may be useful indicators of estuary condition and reveal the importance of managing anthropogenic activities in the surrounding catchment to improve water quality so that biodiversity of fish can be restored in these estuarine environments.

Fruit fly monitoring is an important part of integrated pest management  since  it provides information  about fruit flies species composition in any given  area. The aim of this study was to find out species composition of fruit fly in the City of Sorong, and both Sorong and Raja Ampat Regencies. Sampling was conducted from June to November 2016 using trapping method. There were 19 species of fruit flies in the whole sampling locations, consist of 11 species attracted to cue lure and 8 species attracted to methyl eugenol. Bactrocera frauenfeldi was the dominant species  in trap baited with cue lure, while B. umbrosa and B. dorsalis were dominant in trap baited with methyl eugenol. Fruit fly diversity index in Raja Ampat Regency and City of Sorong were low while diversity index in Sorong Regency was relatively moderate. IntisariMonitoring lalat buah merupakan bagian penting dalam pengelolaan hama terpadu yang memberikan informasi tentang komposisi lalat buah di suatu area.

Abstract. Isroni W, Samara SH, Santanumurti MB. 2019. Short Communication: Application of artificial reefs for fisheries enhancement in Probolinggo, Indonesia. Biodiversitas 20: 2273-2278. Overfishing is one of the biggest challenges in the fisheries sector in Probolinggo, Indonesia. The fish apartment (artificial reefs) was one of the solutions to increase the fish resource since it serves as the habitat for fish to live, spawn, and search for food. In this study, the fish apartment was installed in Probolinggo (Karang Katon and Dringu Beach) from 2017 to 2018. This study showed that five fish species (Caesio cuning, Acanthurus achilles, Acanthurus albipectoralis, Sphyraena jello, and Apagon novemfasciatus) were found in Karang Katon while four species (Chaetodon octofasciatus, Chromobotia macracanthus, Nemipterus japonicas, and Lates calcarifer) lived in Dringu Beach. From a total of 333 fishes, A. achilles was the species with the highest composition level of 51.65% (172) in Karang Katon station. In Dringu Beach station, C. octofasciatus had the highest fish species composition level of 46% (183) from a total of 402 fishes. The diversity index and dominance index in Karang Katon station were low at-1.280 and 0.343, respectively. The diversity index and dominance index in Dringu Beach station were also low at -1.115 and 0.3503. A. achilles had the highest density of 34.4 ind/m3 in Karang Katon station while C. octofasciatus had the highest species density of 36.6 ind/m3 in Dringu Beach Station. From this study, it could be concluded that artificial reefs application enhanced the fisheries in Probolinggo, Indonesia, and help its sustainability.

The Diversity of fish species, composition and abundance from Bodna River in Kwali Area Council, Abuja was studied between May 2018 to April 2019.The aim of the study was to determine the management and sustainable use of the fisheries resources of the Area council. About 1331 fish were collected from the artisanal fishermen during the study period and morphometric indices were determined using standard methods. The fish were identified and counted. Sex ratio 1:2:1 (Males to Females) was obtained indicating a male dominated population. Length –weight measurement indicated that the fish exhibited positive allometric growth pattern. The highest percentage abundant species in the site were Oreochromis niloticus with 34.8% Clarias garienpinus with 28.0% and Pellonula leonensis with 17.6% and the least occurring species were Nannocharax shariensis with 11.0% Mormyrus valenciensis with 7.7%. The seasonal variation of fish distribution was observed to be higher in the wet season with 66.2% than the dry season. Nutrient displayed greater impact on fish abundance in the wet season. The Simpson and Shannon Weiner’s diversity index values were (0.976) and (-1.456) in both richness and evenness respectively. The findings of the study could be helpful to the artisanal fishermen and the community for fisheries sustainability.

Fishes were sampled monthly by different nets in Aksu River Estuary from October 2006 and March 2008. In total, 3347 individuals from 26 species were captured. Mugil cephalus, Vimba vimba and Liza aurata were the dominant species and comprised over 50% of the total number. The fish comprised 10 marine, 14 freshwater and 2 migrant. The index of species richness, Shannon-wiener diversity, and evenness each showed a consistent seasonal pattern. Canonical correspondance analysis indicated that salinity correlated with the seasonal pattern in the fish assemblage.
