Abstract

Porong River Estuary is potentially assumed to be contaminated of heavy metals Pb, Cu and Zn from anthropogenic and industrial activities in Sidoarjo, East Java. This study aimed to analyze the difference of heavy metal contaminations (Pb, Cu and Zn) in water and sediment of mangrove ecosystem located in Porong River Estuaries in September 2014. The location of sampling was selected by purposive sampling method considering the river parts: (1) upstream, (2) downstream and (3) open sea. Analysis of heavy metal contaminations (Pb, Cu and Zn) were performed by using Atomic Absorption Spectrophotometer (AAS). The average concentration of Pb, Cu and Zn in water were <0.0044, 0.0226 dan 0.3555 mg/kg, respectively. While those of Pb, Cu and Zn in sediments were 0.0648, 0.3543 and 0.5653 mg/kg, respectively. It showed significance different of Pb and Cu concentration in water and sediments. On the other hand, there was no difference of Zn concentration between those medium.

Abstract

Tabingal fish (Puntioplites bulu Blkr) is a type of freshwater fish that commonly inhabit the Siak River, Riau. To understand the sex ratio and condition factor of this fish, a study has been conducted in April to October 2009. Total number of fish collected was 131. The sex ratio of this fish during the research period was almost constant (1:1), but the number of male was slightly higher than that of the female. Most of fish collected were 87-241 mm TL and they are categorized as undeveloped gonad fish. The factor condition was ranged from 1.21-1.50.

Abstract

Sixty seven specimens of the young catfish Pangasius sutchi were divided into three groups. The group (A) was young catfish with size (Body Length, BL±STDEV) 5.6±0.4 cm, n = 24, group (B) was 9.4±0.5 cm, n = 24, and group (C) was 15.0±0.9 cm, n = 19. All specimens were forced to swim in swimming channel of the flume tank for examined their swimming performance. The result show that the swimming speed has negative correlation on the swimming endurance. Higher swimming speed will be at lower swimming endurance for three groups of the young catfish. The bigger young catfish had higher swimming performance than smaller. Based on estimation of the burst swimming speed was 86.8 cm sec-1 for group C, 74.4 cm sec-1 for group B, and 57.5 cm sec-1 for group A. The estimation of the maximum sustained swimming speed was higher for bigger than smaller fish, as 10.9 cm sec-1 for group A, 19.7 cm sec-1 for group B and 16.4 cm sec-1 for group C. The relationship between swimming speed and swimming endurance of the young catfish are discussed in detail in this paper.

Abstract

Boiled fish has various disadvantages such as short shelf life, less attractive appearance, consumers are limited, so we need a better product diversification. Research aimed to diversify into shredded boiled fish through substitution experiments of banana male bud 0%, 10%, 20%, 30%, 40%, and 50% (w/w) of the boiled meat mackerel fish. The results showed that the increased substitution of banana male bud tends to reduce levels of protein and moisture content, and tends to increase the fat content. Substitution of male banana bud against boiled fish up to 50% (w/w) produce shredded with characteristics of hedonic, fat content, ash content, and TBA are not-different from the substitution of 0%, but it has a higher yield, more fibrous texture, color brown more bright, water and protein levels the lower. The shredded of boiled fish banana male bud has a 54.26% yield, 5.97% moisture content, 25.86% fat, 33.04% protein, and lightness 34.83 (scale 0-100), so it is still included in the SNI shredded fish.

Abstract

This research was conducted in October 2013 in Pematang Sei Baru village of Tanjung Balai Asahan sub regency Asahan Regency in North Sumatera Province. This study aims to determine the level of environmental friendly sembilang gillnet using Fish Aggregating Device (Tuasan) or FAD and economical feasibility of this environmentally friendly technologies. The method used in this study is a survey method with direct observation both interviews and discussions with fisherman. Observation by using FAO (1995) criteria shows that this fishing gear in combination with FAD could be classified into environmentally friendly fishing gear. The results of the feasibility analysis calculations indicate that this gillnet bussiness proved provide benefits for fishermen and deserves to be developed because of the value of BCR (Benefit Cost Ratio) retrieved of 3.07; FRR (Financial Rate of Return) is 181.91% and PPC (Payback Period of Capital) is only 6 months and 18 days.

Abstract

Mangrove ecosystem in the coastal of Darul Aman Village has been seriously degradated. This condition can affect gastropods live in the area. The purpose of this study was to determine the density and sex ratio of mangrove snails Telescopium telescopium in mangrove ecosystem. This study was conducted in September 2014 in the mangrove ecosystems of Darul Aman Village Rupat Distric. The method used in this study was a survey method. Location study was divided into three stations. Snail T. telescopium sample was collected by hand-picking directly in five plots of 2 m x 2 m for each station. The snail sex determination was done from colour and shape observation of gonad in laboratory. Variance Analysis (ANOVA) was used to test the significance differences of mangrove snail density between stations. During the research, a total of 77 samples of snail mangroves, with sizes ranging from 59.0 to 98.1 mm and a weight of 24.83 to 84.26 g was obtained. Average density of mangrove snails obtained 0.60±0.379 to 2.05±0.411 (ind/m2). Mangrove snail density was significantly different between stations (sig.<0.05). Morisita index value at the third station shows that the distribution pattern of mangrove snail is uniform (Id <1.0). Sex ratio (male and female) of mangrove snails was 1: 1.

Abstract

Snakehead fish (Channa striata) is one of economically valued freshwater fish species, which is potential to be cultivated intensively. However, it has still mirred in the production because of low survival fry rate. The current research aimed to obtain the best stocking density on the survival and growth snakehead larvae rearing in plastic lined pond. Research was conducted in Batanghari Sembilan Fish Breeding Units from 3rd June until 3rd July 2014. This research used a completely randomized design with four treatments and three replications. The treatments were P1 (2 larvae per-litre), P2 (4 larvae per-litre), P3 (6 larvae per-litre), and P4 (8 larvae per-litre). The result showed that the difference of stocking density was significant on survival rate, length and weight growth. Stocking density P1 with 2 larvae per-litre was resulted the highest-value consist of survival rate (63.83 %), absolute length growth (3.61 cm), and-absolute weight growth (3.88 g). Water quality parameters during research in optimal range were temperature 27-32oC, pH 5.2-7.8, dissolved oxygen 2.08-7.06 mg.L-1, and ammonia concentration 0.006 - 0.072 mg.L-1.

Abstract

Penyediaan benih ikan berkualitas dan berkesinambungan menjadi faktor penting dalam peningkatan budidaya ikan. Pengembangan usaha budidaya akan mengalami hambatan tanpa diberengi oleh ketersediaan benih yang cukup dan berkualitas baik. Salah satu cara yang dapat ditempuh untuk menyediakan benih yang berkualitas unggul adalah dengan jalan perlakuan Ginogenesis. Penelitian ini telah dilakukan pada bulan Mei-Agustus 2014 di Laboratorium Pembenihan dan Pemuliaan ikan Universitas Riau. Penelitian ini bertujuan untuk mengevaluasi pengaruh lama penyinaran dan lama kejutan suhu dingin serta pertumbuhan benih ginogenesis ikan selais (Ompok rhadinurus). Metode yang digunakan adalah metode eksperimen, dengan perlakuan lama penyinaran Ultraviolet terhadap sperma ikan dan lama kejutan dingin terhadap telur setelah pembuahan 1 menit pada suhu kejutan dingin 5 oC. Sperma berasal dari ikan patin (Pangasius hypopthalmus), sedangkan telur berasal dari ikan selais (O. rhadinurus). Hasil eksperimen menunjukkan bahwa perlakuan terbaik adalah lama penyinaran 3 menit setelah terjadi pembuahan 1 menit dan lama kejutan dingin 3 menit pada suhu dingin 5oC. Sedangkan pertambahan bobot dan panjang mutlak K-2H dan G-2N meiotik tidak jauh berbeda.
