A single specimen of saltwater crocodile Crocodylus porosus Schneider, 1801 (1.50 cm in length) was captured and photographed by a local fisherman by gill net at fishpond around mangrove ecosystem of east coast Surabaya on December 2020. The location where the estuarine crocodile caught is an important wetland area in Surabaya with an excellent mangrove cover. Wonorejo mangrove location is about 10 km from the centre of Surabaya, the second-largest city in Indonesia. This finding is considered as a first reported of C. porosus in Surabaya, and at the same time is proof of the importance of the mangrove area on the east coast of Surabaya as a habitat for wildlife that must be conserved appropriately. Routine monitoring of mangrove areas, including their wildlife, is essential so that they are not displaced by the development of the city which changes the land function to become a residential area.

Strategy For Development of Untia Archipelago Fishing Area Based on Ecotourism In The City of Makassar This research was conducted from August 5, 2019 to September 5, 2019, aimed at identifying the potential of ecotourism in the Untia VAT Area mangrove ecosystem, analyzing the suitability of the Untia VAT Area mangrove ecotourism, and determining the strategy of developing mangrove ecotourism in the Untia VAT Area. Data collection was carried out through field surveys and interviews using questionnaires. Data analysis uses area suitability analysis for coastal tourism, mangrove tourism category and SWOT analysis. The results of this study indicate that the potential for ecotourism in the mangrove ecosystem Untia VAT Area is a mangrove area included in the appropriate category to be used as an ecotourism area. The strategy of developing mangrove ecotourism in the Untia PPN Region is to increase human resources (HR), planting abrasion-resistant mangrove species in a sustainable manner, procurement of facilities and infrastructure to support tourism activities, and good cooperation among policy makers.

Herein we report a method of assessing DNA fragmentation in the saltwater crocodile using the sperm chromatin dispersion test (SCDt) after including frozen–thawed spermatozoa in a microgel (Halomax; Halotech DNA, Madrid, Spain). Following controlled protein depletion, which included a reducing agent, sperm nuclei with fragmented DNA showed a homogeneous and larger halo of chromatin dispersion with a corresponding reduced nucleoid core compared with sperm with non-fragmented DNA. The presence of DNA damage was confirmed directly by incorporation of modified nucleotides using in situ nick translation (ISNT) and indirectly by studying the correlation of the SCDt with the results of DNA damage visualisation using a two-tailed comet assay (r = 0.90; P = 0.037). Results of the SCDt immediately following thawing and after 5 h incubation at 37°C in order to induce a range of DNA damage revealed individual crocodile differences in both the baseline level of DNA damage and DNA longevity.

Capture Rates

Since 1986 the Conservation Commission of the Northern Territory has operated a programme to remove 'problem' saltwater crocodiles from waters in and adjoining the township of Nhulunbuy. Over a period of five years, 52 different saltwater crocodiles (44 male) were captured. Most (48) were released at remote sites designated by the traditional Aboriginal owners of the surrounding lands. Release distances from the township varied from 17 to 282 km (by coastline). Many crocodiles (47.9%), including those released at the most distant sites, returned to, and were subsequently recaptured at, the township. Total capture rates (initial captures and recaptures pooled) varied seasonally, with fewer crocodiles being caught in the cooler dry season. During the wet season capture rates remained high, but relatively fewer 'new' crocodiles were caught. Probability of recapture could not be related to distance and direction of release from the township, nor size and sex of the released crocodile. Frequency of capture of individual crocodiles (1-8 times) was also unrelated to these variables. The high rates of return indicate that relocation is unlikely to be an effective strategy for managing humancrocodile interactions, at least in areas where potential release sites already support saltwater crocodile populations near carrying capacity.

Main Strategy

One of the resources that has potential to utilization is a mangrove ecosystem. The aim of this study was to analyze the changes in the area of mangroves, analyze the causes of destruction of mangroves, and formulate strategies for sustainability management of mangroves in Sawo District. The changes in the area of mangroves was identified from  imagery and analyzed by ArcGis 10.2.2. The causes of mangrove destruction was analyzed from the data collected from the stakeholders in Sawo District that related to management of mangroves in district level, regency level, and province. The data was analyzed by Analytical Hierarchy Process (AHP) to formulate the strategies for sustainability management of mangroves. The result of landsat imagery showed that, mangrove area has decreased about 17,405 ha within a decade. Mangrove destruction was caused by human activities, such as logging and conversion of mangrove land into agriculture. The main strategy for sustainability management of mangroves was community’s empowerment, then followed by others alternatives. Keywords: AHP, coastal, destruction, ecosystem, landsat

Crocodylus Porosus

Crocodylus porosus is the largest species of crocodile and can be found in estuarine and riverine area in Malaysia. Crocodile in captivity can be found in Malaysia for various purposes such as tourism, conservation and leather industry. However, the management practice in established crocodile farm varies across park for example in terms of feeding regime. Thus, this study focusses on the feeding regime of C. porosus in captivity and evaluation of management of crocodile of Teluk Sengat Crocodile Farm. This study was carried out for 35 days in two different ponds of Teluk Sengat Crocodile Farm, Kota Tinggi, Johor. The results show majority of the food given to crocodile were chicken (64%), followed by fish (28%) and prawn (8%). Prawn was only given to juvenile crocodile every day, while fish and whole chicken were given to adult crocodile once a week. The feeding frequency are adequate for the juvenile crocodile however, the feeding quantity for adult pond are worrying. Future research should be conducted on other captive population of C. porosus in other areas in Malaysia as well to better understand the overall management practices in Malaysia.

Management Approaches

This paper attempts to identify and explicate sustainability approach through innovative management of natural resources that is able to create balance between conservation and utilization of natural resources. Innovative management of natural resources is related to the act of bringing changes or an introduction to a novelty idea for achieving organisational goal which involves organising people, finances and resources, training, controlling, monitoring, and sanctioning. The study focuses on the mangrove ecosystem, one of the most sensitive natural resources in the country, which has been successfully managed by the government through top down approach. Data was gathered through content analysis and interviews with several key persons from the study area. This paper firstly compares the different management approaches in Matang Mangrove Forest Reserve and Kuala Gula Mangrove, before finally elaborating on the innovative management of the latter.
