Abstract The carrying capacity is defined as the ability of aquatic environment to support the life of organisms in that area. A study aimed to assess the aquatic carrying capacity for extensive fishing in the Tanjung Balam Lake, Buluh China Village, Kampar District, Riau. The carrying capacity was determined based on primary productivity using chlorophyll-a value. A research was conducted June, 2019. There were 3 stations namely station 1 (inlet area), station 2 (in the middle of lake) and station 3 (tip of lake). In each stations, there were 2 sampling point, in the surface and depth of 2 Secchi (90 cm). Sampling was done three times, once a week. Water quality parameters measured were chlorophyll-a concentration, transparency, temperature, pH, dissolved oxygen, phosphate and nitrate concentration. Results shown that chlorophyll-a: 6.87 – 25.28 µg/L, transparency: 49 – 54 cm, temperature: 28.5 – 29.8 0C, pH: 5, dissolved oxygen: 3.2 – 7.3 mg/L, CO2 3.9 – 15.9 mg/L, phosphate: 0.042 – 0.148 mg/L and nitrate: 0.0125 – 0.0437 mg/L. Carrying capacity assessment based on chlorophyll-a in the Tanjung Balam Lake was 0.46 tons/year.Keywords: Kampar River, Oxbow lake, Primary Productivity, Water quality

Abstract

Abstract Madong Village is one of the coastal areas that is overgrown by vegetation in the form of seagrass which is a habitat for marine life, among other is gastropods. The presence of community activities around the seagrass ecosystem might affect the quality of waters and organisms associated with the ecosystem, especially gastropods. Information about the species of gastropods in the region is still limited. To find out the species of gastropods in the seagrass ecosystem of Madong Village, this research was conducted in March-April 2019. There are      3 research stations, and each station has 3 line transects with 1x1 m quadrat. The results shown that the gastropods found consisted of 5 families and 6 species, which are: Cerithium coralium, Cerithidea cingulata, Strombus canarium, Strombus urceus, Pyrene scripta, and Nassarius crematus. The conditions of the water quality obtained ware temperature ranges from 30-32º C, current speed 0.15 m/sec, dissolved oxygen 6.7-6.9 mg/L, acidity (pH) 8, salinity 31-35 ‰. The type of substrate at Station I and II is muddy sand, while Station III is sandy mud. Keywords: Madong Village, seagrass ecosystems, gastropods species,Cerithium coralium, Strombus urceus.

Abstract

ABSTRACTA Study on the abundance of Chaetodontidae, coral cover and  relationship of  abudance with coral cover were conducted from May -          July 2019 in the Lagoi Waters of Bintan Regency of  Riau Islands Province. Abudance of fish observed with Underwater Visual Census (UVC) method while coral cover with Reef Check  method. Apparently the abundance of Chaetodontidae fish ranged from 313.3 - 603.3 ind/ha whereas coral cover ranging from 46 - 74%.Forthat, abudance of coral fish corelated (r = 0.977) with coral cover, suggest that, there is a very strong relationship between live coral cover and Chaetodontidae fish. Key words :Chaetodontidae, Coral Reef, Lagoi Waters

Abstract

ABSTRACTDessykristina65@gmail.com   Knowledge about fish behavior is highly needed in developing effective fishing techniques and methods. One of the fish behaviors that can be learned for fishing gear is fish swimming activity. Fish swimming activities can be divided into three large groups, namely suistained, prolonged, and swimming speed. This study uses an experimental method / observation that is the speed and endurance of fish swimming tested on a flume tank with different current speeds in each group of tilapia and this research was carried out in March 2019 at the Fishing Equipment Laboratory, Department of Resource Utilization of the Faculty of Fisheries and Ocean University of Riau. The purpose of this study is to determine and test the endurance of tilapia swimming from various types of fish at different current speeds and to determine the swimming speed and maximum swimming speed.swimming speed maximum sustained of 5 tailed tilapia is 2,2 BL / sec,swimming speed maximum sustained of 10 tailed tilapia is 2,3 BL / sec, andswimming speed maximum sustained of 15 tailed tilapia is 2,0 BL / seconds. Thespeed prolonged of the 5-tailed tilapia group is 2.2 - 8.2 BL / sec, thespeed prolonged of the 10-tailed tilapia group is 2.3–8.0 BL / sec, and thespeed prolonged of the 15-tailed tilapia group is in the range of 2.0 -7.7 BL / sec. These results indicate that at this speed it is good to use active fishing gear to catch tilapia in waters. After knowing the speed of swimming, this tilapia can make an efficient fishing gear in fishing so that it increases fishing yields for fishermen.  Keywords: Fish swimming speed, Tilapia swimming endurance, Water current

Abstract

ABSTRACT                The purpose of this study was to determine consumer acceptance of catfish (Pangasius hypophthalmus) grilled fish cake with different processing. The research method used was the experimental method of making the grilled fish cake with different processing, namely X1 (fried) and X2 (grilled). Then a comparative study was conducted to compare treatment using the t-test. Based on the results of research from organoleptic assessment, the catfish grilled fish cake X2 was significantly different from the catfish grilled fish cake X1 at a 95% confidence level. Viewed from the aspect of appearance X1 7.19 X2 7.44, taste X1 6.93 X2 7.46, texture X1 6.92 X2 7.13 and aroma X1 7.04 X2 7.34 in the catfish grilled fish cake X2 treatment was higher than catfish grilled fish cake X1 treatment. The processing of catfish grilled fish cake with grilled processing was most preferred by consumer acceptance with characteristics of appearance quite brilliant without mucus), taste (specific of grilled fish cake), texture (quite dense and elastic) and aroma (specific of grilled fish cake) with chemical value of ash, fat, protein, moisture, and carbohydrate content was 1.43%, 4.26%, 15.34%, 22.68%, and 53.00%, respectively. Key Words: catfish, grilled fish cake, fried, grilled

Abstract

AbstractMystus nigriceps  is freshwater fish that inhabit the Tarai River. A research aims to understand the morphometrical, meristical characteristics and growth pattern of this fish had been conducted from January to March 2019. Sampling were conducted in the Tarai River, using cast net , scoop net and bamboo trap, six times, once/ two week. Result shown that there were 102 fishes (70.93-181.21 mm TL and 4.12-35.7 gr BW) were captured from the river. There were 32 morphological characteristics measured and 6 meristical characteristics counted. There were 4 morphometrical characteristics differences between male and female. In female fish, the distance between mouth to the eye, body width and the distance between dorsal fin to the adipose fin longer than those of the male, but male has longer  base of caudal fin. The meristical characteristic of the fish were as follow: D.I.6-8, P.II.10-22, V.8-12, A.7-9, C.16-23. The length-weight relationship shown that the growth of male and female was similar, it was negative allometric with  b= 2.339  for male and b= 2.163 for female fish. Keywords: Catfish, adipose fin, negative allometric, fin ray

Abstract

ABSTRACK This research was conducted from June to July in Koto XI Tarusan subdistrict, Pesisir Selatan Regency, West Sumatra Province. This study aims to determine the comparison of boat chart catches in the amount of weight (kg), number of individuals (tails) and fish species before and after midnight fishing in Koto XI Tarusan District, Pesisir Selatan Regency, West Sumatra Province. The method used in this study is a participatory method, which is catching data on catches in the fishing ground (fishing ground) by participating in the process of catching boat fishing gear. All data obtained are processed and processed by t test analysis. The results of this study based on statistical tests conducted there are differences in catches of boat chart fishing equipment based on the amount of weight before midnight and after midnight where thit 4.10 is greater than ttab 3.067 so the initial hypothesis is rejected means that there is a difference in the number of results composition catch between the time before midnight and after midnight. Keywords: Boat Chart Fishing Equipment, Comparison, Test Analysis t
