Abstract

This study was conducted to determine morphometric kijing taiwan at several locations in Minahasa District and North Minahasa regency and its association with the abundance of plankton and water quality. Sampling gravestone taiwan and water quality obtained from the four (4 ) locations: Rap Rap Village, BBAT Tatelu North Minahasa Regency, Paleloan and Tataaran II Village, Minahasa regency. Morphometric measurements kijingg taiwan include dimensional measurements and weighing of the shell. Measurement of shell dimensions include length , width , and thickness. Include the weighing of the weighing of the total, shell weight and wet weight of meat. Water quality measurements carried out directly at the sites include measurement of temperature, pH, dissolved oxygen and water base texture, while the identification of plankton carried in Pathology and Clinical Laboratory of Fish Diseases, Faculty of Fisheries and Marine Sciences, University of Sam Ratulangi. Morphometric measurements will be taken in any of 50 individual kijing taiwan each location. The results of morphometric measurements in multiple locations showed uniform size Tataaran II contained in the Village, the Village and Village Paleloan Rap Rap while in BBAT Tatelu uniformity of size only in size from 7-18 to 9-74 cm was caused by Taiwan in the pool because kijing BBAT Tatelu regarded as pest extermination so regularly done. Relationships shell length and total weight kijing taiwan to change at any time is influenced by several factors such as the condition of gonadal maturation , water quality and availability of food in the waters.

Abstract

An experiment was designed to assess the relative performance of three shelter types on the survival and growth of red-claw crayfish (Cherax quadricarinatus).  A 13 days old juvenile crayfish with an average length of 10 mm were cultured in 400 ml water of glass bowl and were provided with one of 3 types of shelter over 19 days.  The various shelter types assessed were dried coconut leaves, bamboo and Hydrilla.  Juveniles in each bowl were fed with Artemia twice a day morning and in the afternoon. There was no significant effect (P>0.05) of shelter type on the survival rate; however, there was a significant effect (P<0.05) on growth with dried coconut leaves (5.33%) performing significantly better than Hydrilla (2.33%) and bamboo (2.00%).  This experiment showed that the shelter types provided had a significant effect on the growth but not in their survival.Keywords: Survival rate, Growth, juvenile Cherax quadricarinatus, ShelterABSTRAKTujuan penelitian ini adalah untuk menganalisis sintasan hidup dan  pertumbuhan  juvenil lobster air tawar (C. quadricarinatus) dengan shelter yang berbeda. Juvenil lobster yang berumur 13 hari dengan panjang rata rata 10 mm dipelihara dalam wadah toples kaca dengan diberikan ketiga perlakuan selama 19 hari.  Ketiga jenis perlakuan adalah daun kelapa kering, bambu dan Hydrilla.  Juvenil diberi pakan Artemia 2 kali sehari yaitu pada pagi dan sore hari.  Hasil penelitian menunjukkan ketiga perlakuan tidak berbeda nyata terhadap sintasan hidup (P>0.05), namun berbeda nyata (P< 0.05 ) untuk pertumbuhan dengan daun kelapa kering (5.33%), Hydrilla (2.33%) dan bambu (2%).     Penelitian ini menunjukkan bahwa jenis shelter memberikan pengaruh nyata  terhadap pertumbuhan namun tidak berbeda nyata untuk sintasan hidup.Kata kunci: Sintasan hidup, Pertumbuhan, Juvenil Cherax quadricarinatus, Shelter

Abstract

The purpose of this study was to identify sea slugs L. pallescens taken from two different mangroves, namely Rhizophora mucronata and Avicennia marina in Tongkaina waters, Bunaken District, Manado City based on morphology and anatomy as well as shell color. Identification of mangroves and sea slugs refers to the identification book. The results obtained were L. pallescens species with elongated and tapered morphology at the end of the shell measuring 0.3-2.7 cm. The operculum is purple. The color of the shell obtained was 66.85% consisting of dark colors (black, black, orange, brown and gray spots), occupying the stems and roots of the mangrove, while the light colors (yellow, yellow, dark spots and red) were found to be 33.15%, occupying the leaves and stems of mangroves. The high survival rate of L. pallescens was found in the mangrove roots. This species was found in R. mucronata by 65.26% while in A. marina only 34.74%, this could be caused by differences in the shape of the mangrove roots.Keywords: L. pallescens; Mangrove; Shell color; MorphologyAbstrakTujuan penelitian ini adalah mengindentifikasi siput laut L. pallescens yang diambil dari dua mangrove berbeda yaitu Rhizopora mucronata dan Avicennia marina di perairan Tongkaina, Kecamatan Bunaken, Kota Manado berdasarkan morfologi dan anatomi serta warna cangkang. Identifikasi mangrove dan siput laut merujuk pada buku identifikasi. Hasil penelitian yang diperoleh yaitu spesies L. pallescens dengan bentuk morfologi memanjang dan meruncing, pada bagian ujung cangkang berukuran  0,3-2,7 cm. Operculum berwarna ungu. Warna cangkang yang diperoleh 66,85% yang terdiri dari warna gelap (hitam, hitam bercak orange, coklat dan abu-abu), menempati bagian batang dan akar mangrove sedangkan warna terang (kuning, kuning bercak gelap dan merah) didapat 33,15%, menempati bagian daun dan batang mangrove. Tingginya kelangsungan hidup  L. pallescens berada pada bagian akar mangrove. Spesies ini ditemukan pada R. mucronata sebesar 65,26% sedangkan pada A. marina hanya 34,74%, hal ini dapat disebabkan oleh karena perbedaan bentuk akar mangrove.  Kata Kunci: L.

Abstract

Research on plankton organisms in supporting aquatic resource management is very important to do. This study aims to see the structure of the plankton community in the coastal waters of West Halmahera Regency. There were 9 sampling sites, namely the waters of Toniku (TO), Tewe (TW), Dodinga (DG), Tuada (TU), Porniti (PR), Payo (PA), Bobo (BO), Sahu (SH), and Ibu (IB). Plankton observations used the Census-SRC method. The parameters observed were abundance, diversity index, uniformity index, and dominance index. The results showed that the highest phytoplankton abundance was found in the TO area, namely 1.7 x 107 cells/m3 and the lowest was 4.1 x 106 cells/m3 in the PR area. The highest phytoplankton diversity index was found in the PR area, namely 2.075 and the lowest was 1.429 in the IB area. The highest uniformity index of phytoplankton was found in the PR area, namely 0.901 and the lowest was 0.624 in the BO and DG areas. The highest phytoplankton dominance index was found in the IB area, namely 0.350 and the lowest was 0.138 in the PR area. The highest zooplankton abundance was found in the DG area at 2.0 x 106 cells/m3 and the lowest was 3.3 x 105 cells/m3 in the IB area. The highest zooplankton diversity index was found in the TU area, namely 1.981 and the lowest was 1.516 in the IB area. The highest uniformity index of zooplankton was found in the IB area, namely 0.942 and the lowest was 0.761 in the DG area. The highest zooplankton dominance index was found in the BO area, namely 0.266 and the lowest was 0.167 in the TU area. The conclusion of this study revealed that the most common type of plankton found was Bacillariophyceae. While the diversity value shows moderate diversity, the uniformity value shows a high level of uniformity, and the dominance value shows low-moderate dominance.
