Abstract

Danau Gatal merupakan danau alami yang menerima air dari Sungai Rokan saat musim hujan. Danau ini dihuni oleh banyak spesies ikan. Namun, informasi mengenai jenis ikan yang ada di kawasan tersebut masih terbatas. Untuk mengetahui spesies ikan yang ada di Danau Gatal, penelitian dilakukan pada November 2021 s/d Februari 2022. Pengambilan sampel ikan dilakukan seminggu sekali/bulan hingga tidak ditemukan spesies baru. Ikan ditangkap menggunakan alat pemancing, jaring, dan bubu, sampel ikan kemudian diidentifikasi. Hasil penelitian menunjukkan bahwa ikan yang tertangkap terdiri dari 3 ordo, 13 famili, 14 marga, dan 15 spesies. Keanekaragaman jenis ikan (H’) di Danau Gatal sebesar 3,47, indeks dominansi (C) sebesar 0,19 dan keseragaman (E) sebesar 0,52. Nilai kualitas air danau adalah sebagai berikut: suhu 28oC-32oC, kecerahan 39-45 cm, kedalaman 109-111 cm, pH 6, oksigen terlarut 3,9-4,3 mg/L, dan CO2 5,89-7,99 mg/L. Berdasarkan nilai indeks keanekaragaman ikan di Danau Gatal tergolong rendah. Beberapa ikan belum pernah ditemukan di danau itu sebelumnya, yaitu sepimping, kipper, selais, dan kapar.

Abstract

This research was conducted on one of the Siak River tributaries that crosses the urban area in Pekanbaru, namely the Pengambang River. The Pengambang River flow is dammed to become a reservoir; one of its functions is as a source of raw drinking water. Increased activity along rivers and reservoirs certainly has an impact on water quality. The research was carried out in May-October 2023. Water sampling was taken at 3 points each along the river flow and in the Reservoir. The physicochemical water quality parameters measured include temperature, TSS, BOD, COD, DO, pH, TP, Nitrate, and Total coliforms for rivers and reservoirs, while Chorofil-a only for reservoirs. Water quality was evaluated using CCME-WQI, and the results of water quality evaluation according to CCME-WQI in the Pengambang River at all sampling stations could have been bad to marginal. At the same time, in the Reservoir, it was marginal. The CCME_WQI Index value in rivers ranges 42.33 to 54.97, while in reservoirs, it is higher 49-56, it indicated water quality in reservoir better than river. Parameters influencing water quality in rivers and reservoirs, especially TC and BOD come from household waste cage fish cultivation.

Abstract

The quality of the Siak River is gradually deteriorating with the rapid socio-economic development in its tributary watersheds. S. Sibam and Air Hitam are part of the Siak tributaries in the Siak tributary sub-region in Pekanbaru City. The quality of the Sibam and Air Hitam tributaries in the Siak Watershed of Pekanbaru City has been studied to determine the relative pollution level of water quality standards. Water quality measurements were carried out from January to August 2022 at the upstream, middle, and confluence with the Siak River. The pollution level of the Sibam River and Air Hitam River was measured using the pollution index method. The quality of the Sibam River and Air Hitam waters is compared to the quality standards according to The Regulation of Government of the Republicof Indonesia(RGRI) Number 22/2021 Class III. The water quality parameter measured consisted of dissolved oxygen, TSS, pH, BOD, COD, nitrate, nitrite, ammonia, and total phosphate. Pollution index calculations for the Sibam and Air Hitam rivers show light pollution, with index values ranging from 1.75 to 3.57. Nitrite and ammonia concentrations in the Sibam River do not meet quality standards. Whereas in the Air Hitam River, the BOD, nitrite, and ammonia level exceeds the quality standards (RGRI Number 22/2021 Class III). The highest pollution index is in the middle of the river, with settlements on both rivers.Keywords:Pollution IndexWater QualitySibam RiverAir Hitam River

Abstract

Nile tilapia (Oreochromis niloticus) is tolerant of variable aquatic conditions, but fluctuations in growth can be recorded in the macrostructure of its otoliths. This study characterized sagittal otolith morphology, quantified fish–otolith morphometric relationships, described dark growth-check patterns, and evaluated concurrent water-quality conditions in the Deli River Estuary, Belawan Bahari, North Sumatra. Fifty fish (27 females and 23 males) obtained from four artisanal fishing occasions between October and December 2024 were measured for total length, body weight, otolith length, width, and weight. Length–weight relationships were estimated using W = aLᵇ, whereas total length–otolith relationships were assessed by linear regression. Fish measured 180–235 mm and weighed 152–300 g; sagittal otoliths were 4.30–6.77 mm long and 0.0063–0.0630 g in weight. The estimated length–weight exponent was 2.979 in females (95% CI: 2.545–3.414) and 2.463 in males (95% CI: 2.063–2.863), indicating near-isometric growth in females and negative allometry in males. Total length explained 78.4% of male otolith-length variation but only 13.9% in females. Dark growth checks ranged from zero to three; 45 fish (90%) had at least one check, and the first check occurred 0.225–0.300 mm from the nucleus. Temperature was 25–28 °C, pH was 6.0, and dissolved oxygen was 4.09 mg/L. The growth checks indicate episodes of reduced otolith accretion, but their causes and periodicity cannot be assigned without validation. Seasonal sampling, replicate readings, and otolith chemical or physiological analyses are recommended.
