Abstract

Microalgae live in almost all types of waters, including in groundwater. The diversity, fertility, and development of microalgae species in ponds are strongly influenced by the conditions and fertility of the waters. This study aims to determine the types of microalgae found in the Pekanbaru City Pond Waters. This research was conducted in Aquatic Biology Laboratory Faculty of Marine and Fisheries, Riau University by survey method. Sampling locations consist of 4 stations and 3 sampling points. The results showed that there were 13 species of microalgae found in ponds in Pekanbaru City, namely: Scenedesmus quadricauda, Pediastrum duplex mey, Tetrastrum heteracarthum, Spirulina platensis, Microcystis aeruginosa, Chlorella vulgaris, Scenedesmus dimurphus, Pediastrum duplex var, Closeterium parvulum, Coelastrum microforum, Scenedesmus acuminatus, Pediastrum biradiatum and Scenedesmus obligus. Based on laboratory culture results, the highest abundances of microalgae were Scenedesmus quadricauda, Spirulina plantensis and Chlorella vulgaris.

Abstract

Research on the abundance of plankton in Tebing Tinggi Island waters ecosystem, Meranti Island District, Riau Province was conducted in March 2017. The observations focused on the phytoplankton and zooplankton communities at ten stations. The variations in the abundance of plankton on average between the location groups were 4428 - 1716224 cells / m3 and 23938 individuals / m3 (67.73%) respectively for phytoplankton and zooplankton. The structure of the phytoplankton community was observed to be dominated by 5 diatoms. Coscinodiscus, Chaetoceros, Guinardia, Navicula, Pseudonitzshia. However, the predominant genus (> 10%) was Coscinodiscus with an abundance of 664,665.97 cells / m3 (99.47%) at station 5. Of the dinoflagellate group, only Ceratium clans with the highest abundance in station 7 of 324609 cells / m3 with location to the north of the Black Water Strait but still in normal condition. The macroplankton community structure is dominated by the Copepoda group especially Calanoida, Cyclopoida and Nauplius copepods with high densities of more than 50%. On the other hand, information about the mangrove forest ecosystem, and associated fauna in the ecosystem in the coastal area of TebingTinggi Island is still lacking. It is therefore necessary to conduct research that can be used as a basis to create a concept of management of marine resources in the region.

Abstract

Environmental condition and water quality in general may affects the health status of fish and it represents in the structure of fish organs such as the gill, kidney, and liver. To understand the structure of the gill, kidney, and liver of Pangasius hypophthalmus that live in the Tanjung Kudu Lake (good water quality) and in the Sail River that has been polluted, a study has been conducted from November to December 2020. Twelve fishes (6 fishes/river) were analyzed. The tissue was formalin-fixed and processed through alcohol series, paraffin-embedded, 5m sliced and Hematoxylin-Eosin stained. The histological samples were then studied using a binocular microscope Olympus CX 21. The abnormality level of the tissue was categorized using the Histopathological Alteration Indeks (HAI). Results showed that the fish tissues from both study sites indicate light abnormality signs such as hyperplasia, hypertrophy, and lifted epithelia. The HAI was 2 for fish from the Tanjung Kudu Lake and 3 for the fish from the Sail River. This index indicates that the abnormality may be cured as the water quality improved.

Abstract

Osteochilus melanopleurus can be found in the Siak and Kampar Rivers. The Kampar Rivers waters are better than that of the Siak River and it affects the growth of the fish. The growth pattern is reflected in the pattern of otolith growth rings. The research aims to understand the pattern of otolith growth rings of the O. melanopleurus from both rivers has been conducted from January to February 2021. There were 55 fishes captured (28 males and 27 females). The otolith was taken using tweezers and shaved manually using a soft grindstone. The dark growth ring pattern was investigated using a binocular microscope. Results showed the size of fish captured was 220 to 360 mm from Siak River and 310 to 370 mm from Kampar River. In the fish with the same standard length, the size of the otolith from the Siak River is heavier and longer than that of the Kampar River, which means that fish growth from the Kampar River is better than that of the Siak River. The length of an otolith from Siak River ranged from 1.875 – 3.275 mm, the width was ranged from 1.575–2.75 mm and the weight of otolith was 0.0039 – 0.0098 g, while the length of an otolith from Kampar River ranged from 2.375–3.275 mm, the width was ranged from 1.85–2.575 mm and the weight of otolith was 0.0042 –0.0076 g. The maximum number of the dark ring in the otolith from the Siak River was 4 and Kampar River was 2. The distance between the nucleus and the first dark ring of fish from both rivers was varied from 0.1–0.525 mm, and there was no special pattern. This fact indicates that the first dark ring was formed individually and they were not formed by a periodical incidents during the fish life.

Abstract

Pangasianodon hypopthalmus can be reared under biofloc system and short photoperiod. To understand the effect of biofloc system and photoperiod manipulation to wards blood structure of P. hypopthalmus a study was conducted on September to December 2020. This experiment using a factorial CRD design with 2 level for B factor (biofloc and no biofloc), 3 level for P factor (Natural, 18 hours dark, 24 hours dark), 3 repetition. The fish was reared in 110L tank, 30 fishes/tank, fed with fish pellet (FF-999, Provit 781-1 and Provit 781-2). Parameters measured were the number of erythrocytes, leukocytes, the level of hematocrit and leukocrite and leukocyte types. The blood was collected using syringe wetted with EDTA 10%. The number of blood cells was calculated using haemocytometer, while the white blood cells were stained using Giemsa solution and checked under a binocular microscope. Results shown that there is no different blood structure in fish of all treatments. Total erythrocytes are 1,681,111-2,647,777 cell/mm3, total leukocytes are 55.031-55.655 cell/mm3, hematocrit 20.33-38.11% and leukocrite 20.33-38.11%. White corpuscle are basophil 00-3.89%, eosinophils 0-3.67%, lymphocytes 26.67-73.89%, trombosit 1-48.89%, monocytes 13.33-30.22% and neutrophill 0.00-9.22%. Based on data obtained, it can be concluded that the biofloc system and photoperiod manipulation combination do not negatively affects the fish hematology.
