Abstract

Fish behavior is affected by environmental condition, including photoperiod. Tounderstand the effects of different photoperiod toward O. hypophthalmus behavior, astudy has been conducted in Oktober 2015. The fish was reared in fiber tanks size100cm X 50cm dan height 40cm with water circulation system. The tanks were placedunder plastic tents that were completed with light bulb and timer to adjust the time.There were 5 treatments applied, namely Control (natural photoperiod), 24 hours dark(24D), 16 dark and 8 hours light (16D8L), 8 dark and 16 hours light (8D16L) and 24hours light (24L). Fish behavior was monitored hourly for a 72 hours periodcontinuously. Swimming and schooling activities, fish position and respons to light andfood were noted. Results shown that the photoperiod clearly affects the behavior offish. During the dark, fish tend to be in the surface, swimming actively, do not form agroup, sensitive to light and very agresive to take food provided. In contrast, during thelight period, fish less active, tend to form a group in the bottom of the tank, lesssensitive to light and less aggresive in taking food. Based on data obtained, it can beconcluded that photoperiod is affect the behavior of fish in general.Keywords: photoperiod, Ompok hypophthalmus, Behavior, Dark, Light

Abstract

Climbing perch (Anabas testudineus) is the one of freshwater fishes living inRiau. Information on the biological aspect of this fish, however, is limited. Astudy aims to understand the reproductive biological aspect of this fish has beenconducted from January-March 2014. The fish was sampled once/ month for athree months period. They were 153 fishes, 68 males and 85 females, 49-145mm SL and 4-126 gram BW. Sex ratio of females and males was 1:1,25. In eachsampling, male and female fishes in 1st , 2nd , 3rd and 4th maturity stages werecaptured, and only female in 5th maturity level was captured. The gonado somaticindex (GSI) is around 0.0088%-5.8567%. Fecundity is around 4.116-13.998eggs/fish, with mature egg diameter ranged from 0.62-0.69 mm. Microscopicstudy of the ovarian structure showing that the ovary of mature femalesdominated by mature eggs and there were few amount of non vitellogenic andearly vitellogenic eggs. The atretic eggs were found in the ovary of the 5thmaturity level fish only. This structure indicates that the fish may be a totalspawner. The testes of males showing mature sperms throughout the study period,indicates this fish may be able to spawn throughout the year.Keywords: Anabas testudineus, Reproduction, sex ratio, GSI, fecundity, sexreversal

Abstract

Pengambang River was inhabit by numerous fish species, however, information on type and relative density of fish in that river was almost none. To understand the type and density of fish in that river, a study has been conducted from May to July 2014. There were 6 sampling sites, in the upstream (S1-S2), middle (S3) and downstream (S4-S5-S6). The fish was sampled using several net types (mesh size 1.27 inch and 1 inch), scoopnet (mesh size 1.27 inch), gillnet (mesh size 2-7 inch) and bamboo trap (mesh size 2 inch). Samplings were conducted 4 times, once in 2 weeks. The fish collected were then identified based on Saanin (1968), Kottelat et al., (1993), Rainboth (1996), and Kottelat (2013). Relative density and the occurence of each type of fish were analyzed. Results shown that there 34 endemic fish species (14 families) were present. There were Barbodes schwanefeldi, Barbichthys laevis, Cyclocheilichthys apogon, Rasbora argyrotaenia, Rasbora trilineata, Osteochilus kelabau, Osteochilus vitatus, Parachela oxygastroides, Hampala macrolepidota, Tynnichthys polylepis, Lobocheilos schwanenfeldii, Mystus nemurus, Mystus nigriceps, Bagrichthys macracanthus, Kryptopterus lais, Ompok hypopthalmus, Wallago leeri, brachypopterus, Pangasius polyranodon, Pangasius-pangasius, Pristolepis grooti, Oxyeleotris marmorata, Helostoma temminckii, Osphronemus goramy, Belontia hasselti, T. trichopterus, T. leerii, Channa striata. C. micropeltes and Notopterus notopterus. The highest relative density (Fi 46%) was in the S5 (in the river mouth of the Pengambang River), while the lowest (Fi 31%) was in the S1 (in the upstram of the river). The most common fish present was K. lais, R. argyrotaenia, E.metalicus, O. vitatus and P.grooti that were distributed evenly along the river (Fi 83,33%). There were 4 introduced fish species found in the Pengambang River (Fi 12.5%), namely E. metallicus, C. gariepinus, O. niloticus and Trichogaster pectoralis.Keyword: endemic fish , introduced fish, Pengambang River, Pekanbaru, Riau

Abstract

Pangasius polyuranodon is one of freshwater fishes that inhabit the Siak River in Riau. This fish has a high economical value and it is a main ingredient for many Riau’s traditional food. However, information on biological aspects of this fish is limited. To understand the stomach content analysis of this fish, a study has been conducted from January – March 2015. The fish was sampled in the Siak River using of the gill net. Stomach content of the fish was analyzed as a basis to calculate the Preponderance Index (PI). There were 118 fishes captured, but 33 of them had empty stomach and they cannot be used for stomach content analysis. Results shown that the main food of P. polyuranodon was a benthic animal such as gastropods (PI 43.91%), bivalve (PI 17.77%), cricket (PI 5.39%), fish (PI 1.52%), crustacean (PI 1.26%), bones (PI 0.24%) and Elais guinensis (PI 28.49%), leaves (PI 1.19%) and Archidendron (0.05%). Empty shells of gastropods and bivalve and Elaeis kernels were found in the intestine of the fish, indicates that the fish dispose these hard materials through their feces. Based on data obtained, it can be concluded that the main food of P. polyuranodon is benthic animals such as gastropod and bivalve and this fish can be categorized as omnivore leads to carnivore.Keyword: Pangasius polyuranodon, Stomach Content Analysis, Index of Preponderance

Abstract

Sail River is one of the polluted rivers in Riau. A study on fish identification in that river has been conducted in 1981 (Hamidy and Alawi, 1991) and there were 54 species present. The environmental changing during these recent years, however, may affects the fish population in that river in general. To understand the fish type present in the Sail River nowadays, a study has been conducted in December 2014 - February 2015. The fish was sampled from 5 study sites, there were in the upstream of river, under the Imam Munandar bridge, under the Sail bridge, in the Lima Puluh District and in the river mouth of the river. The fish were caught using gill net, lure, and cash net. Fish species are identified based on Saanin (1986) and Kottelat et al. (1993). Results shown that the fish caught during the study were consisted of Cypriniformes (8 species), Osteoglosiformes (1 species), Siluiformes (2 species), Beloniformes (1 species), Cyprinodontiformes (1 species), and Perciformes (10 species). The most common genus was Cypriniformes and Perciformes, and they were captured mostly under the Imam Munandar bridge. Based on data obtained, it can be concluded that the fish species living in the Sail River has been significantly decreased during the last 25 years.Key word : Sail river, Pekanbaru, cypriniformes, perciformes, fish population decrement

Abstract

Osteochilus wandersii or lelan fish is a type of freshwater fish that inhabit the Rokan Kiri River. This fish has high economical value, around Rp 30.000-50.000/Kg. However, information on its biological aspects, especially the reproductive biology is poorly known. To understand the reproductive biology of this fish, a study has been conducted from February to April 2015. Total fish captured was 168 (76 males and 92 females). Sex ratio between male and female was 1:1.2. The GSI of male was 0.45%-0.88% and that of the female was 0.82%-3.86%. The fecundity of the fish were 5,772-9,087 eggs/fish. Egg diameter was 0.2-0.8 mm. The relationship between fecundity and standart lenght was y = 1.379x + 0.883, fecundity and body weight was y = 0.581x + 2.858 and the fecundity with ovary weight y = 0.596x + 3.582. The water quality parameter shown are as follows: temperature 26-28°C, transparency 21.5-41.5 cm, pH 6, DO 5.6-7.8 mg/L, CO2 3.9-5.9 mg/L, and current speed 0.40-0.64 m/s. Data on water quality parameters indicate that water quality in the Rokan Kiri River is able to support the life of the fish.Keyword: Osteochilus wandersii, Rokan Kiri River, GSI, fecundity, and eggs diameter

Abstract

Siak River is the most polluted river in Riau, however, many types of fish, including Rasbora argyrotaenia living in that river. As the water is polluted, the health of the fish in general, including its gill structure might be harmed. A study aims to understand the histological structure of the gill of fish from the Siak River has been conducted in February 2015. Abnormality in the gill was noted and the abnormality level was identified using a Histopathological Alteration Index (HAI). Results shown that the types of abnormality present were hyperplasia, hypertrophy, atrophy, epithelium rupture and congestion. The HAI level (13 - 14) indicate that the gill of the R. argyrotaenia from the Siak River was slight damage. This abnormality might be cured if the water quality in the Siak River is good.Keyword: Siak River, Histopathological Alteration Index (HAI), Histology, Abnormality in the gill.
