Abstract

Thynnichthys thynnoides (Cyprinidae) is a type of freshwater fish that inhabits the Pinang Luar Oxbow Lake. This fish has high economical value, around Rp. 25,000–35,000 /kg. This study aims to understand the reproductive biology of Thynnichthys thynnoides from the lake had been conducted during rainy season from March–April 2016. There were 169 fishes (75.04–199.32 mm TL, 3.78–73.01 gr BW, and 0.01–6.22 gr GW) were collected and measured. There were 145 male and 24 female captured. Sex ratio of males and females was 6:1. In each sampling, there were males in the 1st-5th maturity level, while that of the females were in the 1st-4th maturity level. The gonad somatic index was 0.14–14.90%. fecundity is around 26,250–33,894 eggs/fish, and the egg diameter was 0.33–0.39 mm. This structure indicate that the Thynnichthys thynnoides was a total spawner and they may spawn throughout the rainy season.Keywords : Thynnichthys thynnoides, rainy season, sex ratio, maturity level, gonad somatic index

Abstract

ABSTRACT Channa lucius is one of freshwater fishes that inhabit the Kampar Lama Oxbow Lake. This research aims to determine the type of food present in the fish’s stomach. To understand the type of food consumed by C. lucius, a research has been conducted at July to August 2019. There were 107 fishes captured, but only 38 fish have full stomach. The analysis was conducted using a gravimetric method. Stomach content was analysis as a basis to calculate the Preponderance Index (PI).  Result shown that the main food of C. lucius is fish (PI 98%) and the complementary food is insects (PI 1%). The water quality parameter of the Kampar Lama Oxbow Lake are as follows : temperature 28-29°C, transparency 47.5-48 cm, pH 5, DO 4.06-4.47 mg/L, and CO2 9.98-11.98 mg/L.Keyword : Channidae, gut content, gravimetric method, index of preponderance

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

A study aims to understand the morphological and meristical characteristics, relative growth and condition factor of Trichogaster trichopterus has been conducted on Juni to Agustus 2013. Twenty five fishes (56-84 mm TL and 3,63-6,52 gr) from the Tapung River and 29 fishes (55-102 mm TL and 2,00-15,18 gr) from the FAPERIKA Dam were collected and measured. There were 13 meristical and 25 morphological characteristics have been studied. Meristical characteristics of the fins of the Tapung’s fish were as follows: D. VI-VII, P.9-14, A.IX-XII. 30-36, C.16-22 and those of the dam fish were as follow D.V-VII, P. 9-12, A. IX-XII. 30-36, C.16-21. The number of scales in the frontal area of the dorsal fin was 22-27, in the lateral line was 32-41, above the lateral line was 11-14, below the lateral line was 13-16, around the body was 42-62 and around the base of the tail was 24. There were 5 types of relative growth patterns of the morfological characteristic measured from the Tapung’s fish and that of the FAPERIKA Dam was 1 types. Length-weight relationship of Trichogaster trichopterus from both sampling sites were isometric.Key words: Trichogaster trichopterus, flood areas, Tapung River, morphological characteristic, meristical characteristic

Abstract

ABSTRACT This research was conducted in the waters of the village of Kampung Madong, Kampung Bugis Village, Tanjungpinang City, Riau Islands Province. The aim are to identify Shrimp that come from mangrove ecosystem habitats from the waters of Madong Village. There werw 3 sampling areas, upstream (St 1), middle (St 2) and downstream (St 3), of the mangrove ecosystem. Prawns sampling were conducted once/week for a month period, using a spear and bubu. Morphometrical and Morphological  characteristics of the prawns were analyzed descriptively and the prawns sampled were identified. The results found that there were two types of shrimp included in the Penaedae family of the genus Penaeus that live in the habitat of the mangrove ecosystem, namely (1) Panaeus monodon and (2) Panaeus merguensis.  Detail identification showed that they were Panaeus monodon(37 specimens, 17 males and 20 females)  andPanaeus merguensis(42 specimens, 20 males and 22 females).The waters parameters measure in mangrove ecosystem that is dissolved oxygen 7,3-8,1 mg/L, temperature 28-30oC, clarity148-190,5 cm, salinity 25-30 mg/L, pH 6,5-7,5, O27,3-8,1 mg/ l, alkalinity 52-100 mg/l. Keywords: Kampung Madong, Shrimp, Mangrove, Panaeus monodon, Panaeus merguensis

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.

Abstract

Aek Sidempula River, a small river that has high quality water and it is inhabitedby aquatic organisms such as crabs. Scientific information on crabs living in thatarea, however, is almost none. To understand the crabs present in that river, astudy has been conducted from November 2015 to January 2016. The crabs wascaptured using traditional line fishing. Morphometrical and meristicalcharacteristics on the crabs captured were described based on Ng dan Tan (1998)and Ng and Takeda (1992). The crabs sampled were only 40 crabs, and they werebelonged to a single species namely Malayopotamon tobaense (Potamidae). Thisspecies is medium sized crab, 16 – 49 mm carapace width, with dark purplecarapace. This species is characterized by the presence of first gonopod that hasupward turned tip. Male has bigger chelae and narrower abdomen than that of thefemale.Keywords: Crabs, Potamidae, Malayopotamon tobaense, Aek SidempulaRiver, Pearung Silali, North Sumatera.
