Abstract

Zooplankton has an important role in waters, especially in the food chain, these organisms are consumers I which play a major role in bridging energy transfer from major producers (phytoplankton) to living things at higher trophic levels (fish and shrimp). This study aims to analyze the relationship between zooplankton abundance with phytoplankton and physicochemical parameters in the waters of Kastela, Ternate. The research was conducted from March to April 2017 in the waters of Kastela Ternate City North Maluku Province at 5 stations and 4 periods of sampling. Zooplankton samples were taken by filtering methods. The results showed that there were 20 zooplankton genera from 5 (five) classes namely Ciliate (4 genera), Crustaceae (8 genera), Hydrozoa (3 genera), Rotifera (3 genera), and Urocohordata (2 genera). Zooplankton abundance ranges from 1032 to 10942 cells.l-1, the highest at station 3 periods II (10942 cells.l-1), and the lowest at station 4 period I (1032 cells l-1). The range of values of the zooplankton biological indices is diversity index (0.5005 - 1.8662), uniformity index (0.6521 - 0.9601), and dominance index (0.1661 - 0, 6800). There was a low correlation between zooplankton abundance and phytoplankton abundance and physical-chemical parameters of water in Kastela waters, with determination coefficient is 0.236 and regression equation Y = 35079.107 + 0.030 phytoplankton - 791,251 temperature + 75,417 salinity - 1658,557 pH Keywords: mangroves, macrozoobenthics, organic matter

Abstract

Toman fish seeds (Channa micropeltes) generally come from natural catches in South Kalimantan and Central Kalimantan. A closed system is an effort to efficiency transportation costs by increasing the density of fish in transport media. Efforts to reduce stress levels are very important so that they can transport a lot, have small deaths, and take a longer time, and do not disturb the physiology of the fish after transportation. The purpose of this study was to determine the effect of giving 3 ppt salt in transport media to the survival of fish during transportation. This research consists of two stages of activity, that is stage one is transportation for 12 hours and stage two was post-transportation maintenance for 11 days. In stage one, the plastic bag is filled with 10 L of water and is packed according to the treatment. This study used a Completely Randomized Design (CRD) with 4 treatments 3 refitition to produce 12 experimental units. K treatment density of 30 heads / bag with no salt water (0 ppt) and treatment A: B: C with density (30: 50: 70) tail / bag with salt water (3 ppt). The calculation of the highest survival rate in treatment A was 97.80%. The results of analysis of varians (ANOVA) that the treatment has a real effect on survival rate in fish seed transport toman. This shows the best density in this study is 30 heads / bag. Keywords: redsnackhead Fish, Channa micropeltes, transportation, salinity

Abstract

The use of probiotics (Lactobacillus  sp.) in feed is one alternative that is done to improve immunostimulants, growth stimulants, and can be used as a balance of microorganisms in digestion. This study aimed to evaluate the growth performance of vanamei shrimp fed with the addition of Lactobacillus  sp. with sweet potatoes in feed. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment was by feeding with different sweet potato concentrations: A) The dose of sweet potato in feed was 0% (as control); B) The dose of sweet potato in feed was 10%; C) 1The dose of sweet potato in feed was 15%; and D) The dose of sweet potato in feed was 20%. Data were analyzed using variance analysis (ANOVA) and continued with W-Tuckey's further test. The research parameters were digestive enzyme activity, nutrient digestibility, and growth. The results of the variance analysis showed the addition of various sweet potato concentrations with Lactobacillus sp. has no significant effect (p> 0.05) of the growth rate. The specific growth rate of vannamei shrimp ranges from 3.06 to 3.23% / day. Based on the results of the analysis on the utilization of sweet potatoes as a prebiotic on the performance of Lactobacillus sp. in the vannamei shrimps (Litopenaeus vannamei) digestive tract can be concluded that the growth performance does not have a significant effect after being fed with the addition of Lactobacillus sp. and sweet potatoes in feed.

Abstract

Sponge is one of the biota that makes up coastal and marine ecosystems, especially in coral reef ecosystems and seagrass beds in both tropical and subtropical waters. The lack of research and knowledge about sponges (Porifera; Demospongiae), especially in the reef flat ecosystem on Barranglompo Island, is considered necessary to be studied and equipped for research on marine biological resources in the future. This research was conducted in March-November 2019 on Barranglompo Island. The purpose of this study was to determine the diversity and species composition and density of sponges (Porifera: Demospongiae) in the reef flat of Barranglompo Island, Sangkarang District, Makassar City. The method used in sponge data collection is a belt transect starting from ± 50m of shoreline drawn perpendicular to the end of the back reef at each station. The diversity of sponge species found was 22 species belonging to the Demospongiae class. The diversity of sponges on Barranglompo Island is still quite diverse, with a fairly even distribution.

Abstract

Coral reefs are organisms that live on the bottom of the waters and are in the form of limestone (CaCO3) which is strong against sea waves so that it can prevent coastal erosion and is also a place for various types of animals associated with coral reef ecosystems that utilize coral polyps. as his food. Mega-benthos are biota / organisms with a size of more than 1 cm that live on or in the seabed, including the sticking, creeping and burrowing biota that is visible with the camera. The research was conducted using the Line Intercept Transect Method and the Benthos Reef Check Method. The results showed that the highest percentage of live coral cover was found on Badi Island 71.46% (Good coral condition category), the moderate coral condition category was represented by Kapoposang Island (46.02%) and the bad coral condition category was represented by Ballanglompo Island ( 7.92%). The highest diversity of species (H ') Mega-benthos is at station 3 (Badi Island) with the value of H' = 2.528 while the lowest is at station IV (Lumu-lumu Island) with the value of H '= 0.6365. So that the category of the megabenthos species diversity index in the research location can be said to be in the low to moderate category.
