Abstract

Anemon laut merupakan salah satu jenis hewan dari filum Cnidaria. Mereka dapat dibudidayakan dan diperbanyak secara vegtatif dengan metode fragmentasi. Fragmentasi adalah sistem reproduksi secara aseksual dengan cara pembelahan bagian tubuh sehingga membentuk individu baru yang berasal dari satu individu sehingga mempercepat proses reproduksi. Namun cara fragmentasi ini sering menemui kendala, yaitu rendahnya tingkat kelangsungan hidup (survival rate), serta performa morfologis yang mengalami pemutihan. Hal ini disebabkan karena adanya gangguan dari algae berfilamen serta ketidakmampuan anemon beradaptasi pada kondisi lingkungan buatan. Penelitian bertujuan untuk mengetahui pengaruh cahaya terhadap kelangsungan hidup dan tampilan morfologis anemon pasir (Heteractis malu). Percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) yang terdiri atas 3 perlakuan, dan masing-masing perlakuan diulang sebanyak 4 kali. Hasil penelitian memperlihatkan bahwa keberadaan cahaya sangat mempengaruhi kehidupan anemon. Namun demkian, intensitas cahaya tidak berpengaruh signifikan terhadap tampilan morfologis anemon. Ketiadaan cahaya akan membuat tampilan morfologis anemon (warna tubuh) semakin pucat. Cahaya berpengaruh signifikan terhadap tingkat kelangsungan hidup anemon pasir (H. malu). Kondisi yang gelap tanpa cahaya akan menurunkan tingkat kelangsungan hidup anemon.

Abstract

Bullet tuna (Auxis rochei Risso 1810) as an export commodity, have a positive impact on Indonesia's foreign exchange. Utilization status is fully exploited, and captured gonad immature. The aim of this study is to estimate the utilization, growth, and population of bullet tuna. Conducted in Labangka (Sumbawa Regency) during May-August 2019. The compilation of the fork length frequency data (FL) of bullet tuna uses sampling, observation, dialogue and documentation techniques. Alleged utilization level of bullet tuna resources is calculated using a surplus production model. Growth parameters (K and L?) were estimated by the Electronic Length Frequency Analysis (ELEFAN I) method on the Scanning of K-values FAO-ICLARM Stock Assessment Tools II (FiSAT II). FiSAT II software is also used for population estimation based on FL frequency data. Tuna fishing in Labangka uses surface longlines and outboard motorboats. The status of the utilization of bullet tuna in the waters of southern Sumbawa reaches fully exploited and low growth rates. Bullet tuna fisheries activities in Labangka are small scale fisheries that apply the rules of responsible fisheries. So that management is sustainable, it can be done by increasing the size of the fishing line, beginning with the socialization to fishermen.

Abstract

Little tuna or Kawakawa (Euthynnus affinis) or tongkol banyar (Indonesian) are one species of neritic tuna landed in Bangko-Bangko (Lombok Barat District) and Labangka (Sumbawa District). This study aims to determine the feasibility status of kawakawa catch with fisheries biology parameter approach, namely growth pattern (b), condition factor (K), length captured (Lc), and length maturity (Lm). Survey methods and sampling, documentation, interview, and observation techniques were chosen to collect data that were processed quantitatively. Comparative data analysis to obtain justification, relevance and/or contradiction between results and status with theory and policy. Kawakawa are caught by fishermen in Lombok Strait and Indian Ocean in south Sumbawa using surface longlines and gillnets, which are selective fishing gear. Based on the parameters of the condition factor, many of kawakawa have flesh (K>1.0) so that their status is worth catching and worth selling.  The growth pattern parameter is hyper allometric (b>3.0), so that the status is worth catching and worth selling. The technology performance of catching kawakawa in the study location has a dangerous status (Lc/Lm<1.0), which means that the kawakawa captured have never maturity have never matured. That fishing technology of kawakawa is not environmentally friendly in terms of fish resources conservation, especially in preservation and protection. Thus the kawakawa in Lombok Strait and Indian Ocean in south Sumbawa were not eligible to be captured during February-July.

Abstract

White-spoted rabbitfish (Siganus canaliculatus Park 1797) or serpik (Sasak) are very popular with the community as consumption fish. The condition of resources is very worrying along with the shrinking area of ??seagrass ecosystems as a habitat for white-spoted rabbitfish. The purpose of this study is the eligibility of parent candidate of white-spotted rabbitfish. The study was conducted from 1 June to 31 July 2018 in Serewe Bay, south of Lombok Island. Data were collected using a survey-descriptive-independent method with sampling, observation, documentation, and dialogue techniques. Data consists of primary and secondary, quantitative and qualitative data groups, as well as numeric and logarithmic. Biologically, white-spotted rabbitfish from Serewe Bay has a thin body (minor allometric) and slightly flat (not fleshy). The biological status indicates that the gonads do not yet contain eggs and sex cells, so they are not eligible to be candidates for parent. However, the level of maturation is quite high where almost all of the fish samples observed are worth catching, which means the fish have passed the length of the first time the gonads mature (maturation). To get a decent and productive white-spotted rabbitfish parent, it is recommended to catch the prospective parent after the mating season ends.

Abstract

Coastal waters in the south of Sumbawa Island as a habitat for coral reef ecosystem in a potential habitat for the life of reef fish resources. One of them is red snapper or Malabar snapper or Malabar blood snapper (Lutjanus malabaricus Schneider, 1801) which contributes to increasing the value of Indonesia's exports. The problem of Malabar blood snapper fisheries management is population degradation and over exploited. This study aims to estimate the sustainability status of fisheries management of Malabar blood snapper in the coastal waters of the Indian Ocean. Data compilation was carried out during the period June-July 2019 in Cemplung Beach, Labangka, Sumbawa Regency. The sustainability analysis of the of Malabar blood snapper fisheries management applies the technique of Rapreefish (Rapid Appraisal for Reef Fisheries) which was modified and developed from Rapfish (Rapid Appraisal for Fisheries). Sustainability studies were carried out on the biological dimension (11 attributes) as an output factor, and the technology dimension (16 attributes) as an input factor. Management of Malabar blood snapper fisheries involving fishermen and collector?s trader has been carried out conventionally. The result is the level of utilization and exploitation of the Malabar blood snapper resources each overfishing and over exploitation. While the biological dimension, the management status is "Quite Sustainable", and the technology dimension is "Less Sustainable". Improving the management's sustainability status requires intervention from strategic stakeholders. The purpose is toincrease the size of the captured Malabar blood snapper and catching it in potential fishing grounds.

Abstract

Mangroves, a vital coastal ecosystem on earth, are threatened due to human destructive activities. Current, accurate, and reliable information on the extent of mangroves and its distribution is limited. Partial monitoring requires more comprehensive approach, especially in calculating the areal extent in a certain period of times. Therefore, monitoring by analyzing Landsat imagery could provide accurate and reliable data in determining the areal extent and spatial distribution of mangroves. We used publicly available Landsat data during the period of 1997-2018. The data, subsequently, was analyzed by supervised maximum likelihood technique and followed by a direct field validation with the total sample of 45 points (33 mangroves and 12 non-mangroves). The results of Landsat imagery analysis of 5 TM (1997) and 8 OLI (2018) reveal that approximately 82.22% and 86.67 of overall accuracy with the areal extent of mangroves in 1997 was about 44.75 Ha, increasing to about 88.83 Ha in 2018. This represents a significant increase of mangroves extent during that period as it is a result of reforestation. Rhizophora stylosa dominates the mangroves closed by Cemara beach, while Sonneratia caseolaris is abundant in the estuary. This information could be used as a basis for policy makers to create a sound regulation to mitigate the mangroves destruction as well as forcing the conservation efforts in Lembar Bay.
