Abstract

Banyaknya industri yang berkembang saat ini menyebabkan meningkatnya kadar logam berat seperti merkuri dalam perairan. Penelitian ini bertujuan untuk mengetahui kerusakan struktur jaringan lambung ikan kakap putih (L. calcarifer) yang dipaparkan pada [Hg (NO3)2] dengan konsentrasi yang berbeda. Dalam penelitian ini, ikan dipaparkan dengan konsentrasi 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm dan 9,97 x 10-1 ppm. Total ikan yang digunakan untuk histologi adalah 15 ekor. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi [Hg (NO3)2] maka kerusakan pada jaringan lambung ikan juga akan meningkat dan mempercepat waktu kematian ikan. Kerusakan yang terjadi yaitu Hipertropi pada sel mukosa lambung, hancurnya villi, terdapatnya ruang antar lapisan otot dan villi serta menipisnya lapisan villi pada konsentrasi [Hg (NO3)2] yang lebih tinggi. Many industries today lead to increased levels of heavy metals such as mercury in water. This research aims to determine the effect of different concentrations of [Hg (NO3) 2] to Asean Sea Bass (L. calcarifer): Gill Histology. In this study, this fishes was treated with 3,16 x 10-2 ppm, 9,99 x 10-2 ppm, 3,16 x 10-1 ppm, and 9,97 x 10-1 ppm. Total fishes used for histological study was 15 fishes. Results of this research showed that increasing the consentrations of the [Hg(NO3)2] will also increase the damage on the stomach structure and fasten the mortality time of the fish. Damage that occurs is hypertrophy aand hyperplacia on epitel cells, , fuse of secundary lamellae and haemorhage on gill that were exposed to high consentration of [Hg(NO3)2].

Abstract

In the Siak River, Riau, the water quality in the downstream area is relatively bad due to pollutant originated from several sources such as industrial and domestic wastes. The low quality water may negatively affects the growth of fish and it is reflected in the growth pattern in the otolith of fish living in that river. To understand the growth pattern in the otolith of Pristolepis grooti (Anabantidae)living in that river, a study has been conducted. Totally 25 fishes were captured from the downstream of the Siak River. The otolith were then removed and processed following Windarti (2007) and investigated under a binocular microscope to study the growth ring pattern in the otolith. The number of dark growth ring was counted. Results shown that 2 to 5 dark growth rings, around 0.086 mm thick were present in the otolith of the fish. The presence of the dark growth rings in the otolith indicated that the growth of P. grooti in the downstream of the Siak River was hampered and this fact also suggested that the water quality in the downstream of the Siak River is not sufficient to support the life P. grooti in that area.

Abstract

The presence of fish cage culture activities may affects the environmentalcondition as the remain of fish feed pellets may enter the surrounding water and itmay serve as food resources for wild fish species such as Puntius schawanefeldi .To understand the impact of fish floating cage activities on feeding habit of P.schawanefeldi and economical condition of traditional fishermen in the KotoPanjang Dam, a study has been conducted on April to June 2013. Fish sampleswere collected from 5 stations, Stations 1, 2 and 3 were in the dam, around thecage, while station 4 and 5 were in the area that has no cage. Data of 24 hoursfish feeding habit were obtained by capturing fish for a 3 days period (once/ 3hours, at different time). Stomach content was then removed, identified andanalyzed using a volumetric method. Results shown that the stomach content offish living around the cage and the fish living far from the cage are different.Stomach content of the fish from the 1 st , 2 nd and 3 rd stations was dominated byfish feed pellet remains (>90%), while that of the fish living in the area with nocage was dominated by debris (>90%). These facts indicate P. schawanefeldi is anopportunist fish, its feeding habit is changing. Fish living around the cage preferto feed on commercial fish feed pellet remains. The presence of P. schawanefeldiaround the cage, however, increase the income of traditional fishermen as theyable to caught around 50 – 80 kg of fish/ week, compare to 10 – 20 kg fish/ weekin the 4 th and 5 th stations. Data obtained indicate that the presence of fish cageaffect the feeding habit of P. schawanefeldi and positively affect the income of thetraditional fishermen.Keywords: Puntius schawanefeldi, feeding habit, fish floating cage, KotoPanjang Dam

Abstract

Kryptopterus apogon is one of the freshwater fishes that inhabit the Danau Baru oxbow lake. This study aimed to understand the stomach content of the fish living in the lake and also to understand its reproductive biology during the period of December-February 2017.The number of fish captured were 45 fishes ( 24 females and 21 males). The stomach content was analyzed using a gravimetry method, while its reproductive biology was noted.  K. apogon is as carnivorous fish and the types of food present in the stomach was fish (98.644%) as main food, crustaceans (0.940%) and insects (0.001%) as additional food. Mature fishes (13 females and 14 males) present throughout the research period, but the peak of reproductive activities occurred in February.  The Maturity Index of female ranged from 0.09-5.45% and that of the male was 0.07-0.18%. The fecundity of the fish was 36.075-540.72 eggs (in 340-690 mm TL and 197.5-1.725 gr BW females). This fish is total spawner,  and the diameter of eggs from the anterior, middle and posterior parts of the ovary was around 0.866 mm. These fish tend to consume fish during its gonad development.

Abstract

This researct was conducted on September 2015 to April 2016. Fish reproduction is controlled by endocrine system that is affected by external factors such as photoperiod. Changing in photoperiod may affect the gonad development in fish. To understand the effect of different photoperiod in gonad development of O. hypopthalmus, the fishes were reared in fiber tanks (140 x 60 x 40 cm) with water circulation system and completed with aerator. The treatments applied were : natural photoperiod, 24D (continuous dark), 16D8L (16 hours dark and 8 hours light), 12D12L (12 hours dark and 12 hours light), 8D16L (8 hours dark and 16 hours light) and 24L (25 continuous light), and the fish were feed on shrimp and cricket enriched commercial pellet. The fishes were sampled once/month, 4 fishes/sample. Parameters investigated were body length, body weight, gonad development, hepatosomatic index (HSI), viscerosomatic index (VSI) and gonadosomatic index (GSI). Based on the research  results different photoperiod did not affect the gonad development of O. hypopthalmus. There was no special pattern in gonad development in all treatments. The gonads were first developed in 13 – 37 weeks old male and female fishes. The female gonad, however, developed earlier than that of the male. The smallest female with developed gonad was 10.65 cm TL and 5.55 g BW. While that of the male was 16.7 cm TL and 16.7 g BW. During the research there was no mature fish.  The HSI and VSI shown similar patterns, it was increased by the second month (17 weeks old fish) and then decreased. This decrement indicates that the energy stored has been used for gonad development. Based on data obtained it can be concluded that the photoperiod does not affect the gonad development of ompok hyopthalmus.
