Abstract

Cibanten watershed upstream is from Karang Mount (one of that is shallow lake Cibanten water springs), flow in Serang City and the downstream at Banten Bay. From upstream until downstream, Cibanten watershed used by various anthropogenic activities where potentially to increasing trophic state of the waters. This research aimed to evaluate trophic state of Cibanten watershed. Research conducted at April – Mei 2018. Water sample took and measured at three different location, upstream (code: Hu), Central (code: T) and downstream (code: Hi). Water parameters where in-situ measurement was water depth, temperature, secchi depth, water colour, pH, dissolved oxygen and salinity (special for downstream). Water sample analysed at Aquaculture Laboratory of UNTIRTA, the water parameter was phosphate and chlorophyll-a. Trophic state of Cibanten watershed analysed with Trophic State Index (TSI). The result from upstream of Cibanten watershed categorized as mesotrophic, with maximum secchi depth until water bottom and existed some water plant. In the central and downstream of Cibanten watershed categorized as light eutrophic. The significant different between upstream, central and downstream of Cibanten watershed is secchi depth. Low secchi depth at central and downstream due to water turbidity, shown by water colour is yellowbrown that assumed come from suspended solid contents.

Abstract

Situ Cipondoh is favorite location for the fisherman in Tangerang Regency andthe surrounding area. The aim of the research is to know characteristics andperception from the fisherman to Situ Cipondoh and economic value ofrecreational fishing in Situ Cipondoh. The research using primary data which iscollected by accidental sampling from 50 fisherman. Valuation of recreationalfishing in Situ Cipondoh using travel cost approach. Average respondent age are34 years old, graduate from Senior High School and earn money about2.000.000,00 IDR – 3.000.000,00 each month. They usually come alone and stayfor fishing about 6 hours and more. Significant factor that affect the number oftourists is the number of fish catched. Based on the calculation, value ofrecreational fishing in Situ Cipondoh estimated at 281.687.255,62 IDR perannum.

Abstract

Sinodontis is one of the ornamental fish that have high economic value, because of its unique behavior which could swim in reversed position. The purpose of this study was to determine whether there are differences in the effect of incubation temperature on hatching time and hatching time of sinodontis eggs, and to know the optimal temperature for the time of hatching time and hatching rate of the sinodontis eggs. The main parameters measured were the hatching time and hatching rate of sinodontis eggs. This experiment used completely randomized design with 4 treatment temperature difference, A (25-26oC), B (28-29oC), C (31-32oC) and D (control), with 3 replications. The results showed that the fastest hatching time of sinodontis obtained in treatment C at 1120 minutes (18 hours 40 minutes), then treatment B at 1240 minutes (20 hours 40 minutes), then treatment D at 1340 minutes (22 hours 20 minutes) and longest hatching time in treatment A at 1760 minutes (29 hours 20 minutes). Highest hatching rate of sinodontis obtained in A treatment that was equal to 94.67%, then C treatment that was equal to 82.67%, and treatment D amounted to 81.33% and lowest hatching rate in treatment B 80.00%. Based on the results of the study showed that the optimal temperature to accelerate the sinodontis for hatching time was at a temperature of 31-32oC, while the optimum temperature for increasing the hatchability of sinodontis eggs was at a temperature of 25-26°C.

Abstract

A strong demand for high quality of fish seeds can not be fulfilled by the production of seed in the area of Serang district. Many people have to fulfill their needs from out side Banten area. Therefore, in order to support in solving the problem, the Office of Marine and Fisheries Servise of Serang District Government through their laboratory of fish breeding (BBI) in Baros Serang, proposing the development of breeding facilities to enlarge the increasing demand of high quality of fish seeds. This program is important to support the developmen in fish culture in Serang district as well as in Banten Province. A feasibility study for the development of the laboratory of fish breeding have been done on December 1 to 30 March 2011 with using qualitative descriptive analysis method, a simple quantitative analysis and measurement of water quality. Location of the BBI Baros was very suitable, However, the land Area of BBI is inadequate to operate in large scale production. Accordingly, in implementing fish farming based on Indonesian National Standard (SNI), Ways of Good Fish Hatchery (CPIB), Fish Ways Good (CBIB) and stem and seed certification requires Laboratory facilities are adequate. The optimal areas for fish breeding laboratory is about 4 hectares, to prepare the large production scale.

Abstract

Snakehead is a kind of fresh water fish that still taken from the nature, which is the yieldof it fishing are unreliable. Therefore, the aquaculture technique is needed. Criticalphase of snakehead aquaculture is choosing suitable feed for larvae. Based on this problem, information about first feed suitable for larvae is very important.The aim of the research is to know about growth and survival rate of snakehead larvae with differentfeed. The research was done in 21 days at the Center for Research and Development ofFreshwater Aquaculture Bogor. Larvae with first weight 0.4±0.07 mg and length 4.56±0.53 mm were used. Fish were feed three times daily in ad satiation. Experimentaldesign used was completely randomized design four treatment with three replications,namely A (egg yolk chicken), B (Moina sp,), C (Artemia sp.) and D (silk worm).Parameters measured were the absolute length growth, the growth of absolute weight,specific growth rate, survival rate and feed efficiency. Water quality parameters weretemperature, pH, DO and conductivity. The result showed that the used of silk worm asfirst feed for larvae indicated the best performences. The growth of the absolute length of13.34±1.30 mm, absolute weight of 54.52±2.93mg, specific growth rate 23.85±0.21%,survival rate 97.67±2.36% and feed efficiency 82.69±7.79%.  Keywords : feed, growth, larvae, silk worm, snakehead, survival rate.

Abstract

Helminth is one of the many parasitic groups found on the body of the fish. The helminth parasitic can inflict harm ecologically, biologically and economically. Monitoring of the distribution of disease in fish is crucial especially when the fish has a pattern of migration from one place to another. Fish sampling was carried out in September – October 2012 from the place of landing of Fishes (TPI), i.e. TPI's Pelabuhan Ratu (West Java province), TPI Karangantu (Banten Province), TPI Bandar Lampungprovince of Bandar Lampung), TPI Muara Angke (DKI Jakarta), and TPI BanyuwangiEast Java province). As many as 160 of 218 R. brachysoma (a prevalence 73.38 %), and number of intencity is 1.378 ± 11.96. The helmint parasitic is a Lechitocladium angustiovum (Digenea: Hemiuridae), Lecitochirium sp. (Digenea: Hemiuridae), Prodistomum orientalis (Digenea: Lepocreadiidae) and Anisakis typica (Nematodes: Anisakidae). Differences in characteristics of R. brachysoma habitat will cause differences in the amount, intensity and prevalence of the helminth parasitic species investment in an area. This is related to the behavior of eating and food availability of R. brachysoma. The distribution of the helminth parasitic in the digestive organs is on intestine (13.72%) and stomach (86.28%), utilizing the existing nutrients as food. In very small amounts, the relationship between the parasite and its host is a mutually beneficial symbiotic relationship but in great numbers, the helminth parasitic infection can lead to secondary infections on the infected organs and can lead to decreased metabolism.Keyword: distribution, helminth parasites, short body mackerel, Jawa Sea, Rastrelliger brachysoma
