Abstract

Introducing Biofilter as a Technique for Solving a Problem of Organic Pollutan at Brachiswater Pond at Lakkang Village, MakassarAbstract: Fish/shrimp culture at pond is one of income source for coastal community. Water sources for brackhiswater pond come from river and estuary.  The quality of water source for this pond depend on the quality of river and estuary.  On the other side, people use river to through it their waste not only domestic waste but also industrial waste along the river, consequently the pollutant in the river is high. Brackishwater pond along Tallo river has a source of water from River and Tallo Estuary.  A high organic concentration in the Tallo River has a significantly effect to the production of shrimp/fish pond.  A low water quality due to high organic matter could decrease the production of pond and farmers could not be able to grow out fish/shrimp for all year due to in particular month was occurred an increasing significantly of organic pollutant in the river. Introducing biofilter method to farmers for increasing  pond water quality and reducing organic waste in the pond is very important, so farmer could apply this simple biofilter technique for solving a problem of a high organic matter in their pond.  Applying biofilter techinique could be expected increasing water quality in the pond, consequently it could increase shrimp/pond production of farmers.Keywords: Biofilter, organic pollutant, Shrimp/fish pond, Tallo River and Lakkang Village.Abstrak: Budidaya ikan/udang di tambak merupakan salah satu sumber pendapatan masyarakat pesisir.  Sumber air di tambak biasanya berasal dari sungai dan muara sungai.  Kualitas sumber air di tambak sangat tergantung kepada kualitas air sungai dan muara.  Di sisi lain, sungai merupakan tempat pembuangan limbah baik limbah domestic maupun limbah industry yang ada di sepanjang sungai sehingga kandungan limbah baik limbah organic maupun non organic cenderung sangat tinggi di perairan sungai. Pertambakan di sepanjang muara sungai Tallo, Kelurahan Lakkang sumber airnya berasal dari Sungai dan Muara Sungai Tallo.  Tingginya kandungan bahan organic di perairan Sungai Tallo sangat mempengaruhi produksi tambak masyarakat. Kondisi kualitas perairan yang rendah karena tingginya kandungan bahan organic menyebabkan semakin turunnya produksi tambak dan masyarakat tidak dapat membudidayakan ikan dan udangnya sepanjang tahun karena pada waktu-waktu tertentu terjadi peningkatan limbah bahan organic yang signifikan. Pengenalan metode biofilter untuk meningkatkan kualitas perairan tambak dan mengurangi limbah organic di tambak sangat penting untuk dilakukan sehingga masyarakat dapat memanfaatkan teknologi sederhana biofilter untuk mengatasi masalah tingginya konsentrasi bahan organik di tambak.  Dengan penerapan teknologi biofilter ini diharapkan terjadi peningkatan kualitas air tambak yang akan meningkatkan produksi budidaya udang/ikan.Kata kunci: Biofilter, pencemaran, bahan organic dan Kelurahan Lakkang.

Abstract

Kapoposang Island and the surrounding waters has been appointed by Indonesian Governmet to be a part of waters tour park in South Sulawesi, implying the requirement of the marine resources, including seagrass ecosystems in this area, should be well managed in order to provide biodiversity protection and sustainable use of the seagrass ecosystems. For this purpose, one of basic required information is seagrass distribution and habitat structure. This study was aimed to 1) observe the location of continues seagrass beds, 2) identify the habitat structure in each site of continues seagrass beds. A combination of visual observation and transect method was applied to determine the sites of continues seagrass beds, while seagrass habitat structure was identified based on ecological habitat structure model. Study results revealed that continues seagrass beds were only found in five different sites of Kapoposang coastal waters. Seagrass habitat structure among the five sites were in variable and the highest seagrass cover was found in two sites, namely 1) site A in the north-west part of the island (S04o41'42.5"; E118o56'59.5") dominated by Thalassia hemprichii and 2) site E located in the north part of the island (S04o41'57.8"; E118o57'45.7") dominated by Enhalus acoroides. Both of these sites were different in heterogeneity but similar in complexity. Keywords: Thalassia hemprichii, Enhalus acoroides, continues seagrass beds, habitat structure

Abstract

Purse seine fishing gear is designed to catch both large and small pelagic fish, and commonly used in tuna fisheries. However, this gear is not size-selective, and can pose a threat to fish stocks. The aim of this study was to obtain information on the biological characteristics of little tuna (Euthynnus affinis) caught by purse seiners operating in the waters of Herlang District in Bulukumba Regency, South Sulawesi, Indonesia. Data collected from March to May 2019 included little tuna fork length (FL), weight, sex, and gonad maturity stage (GMS). Fish characteristics analysed in this study were length-weight relationship, size distribution, life phase, and gonadal maturity. Analyses were performed in MS Excel 2010 and Graphpad Prism v.5.03. Male and female little tuna had isometric growth patterns. Modal length class was 24.0-24.4 cm for males and 23.0-23.4 cm for females. All fish caught were below 30 cm TL, while the mean size at first maturity for this species is 39.8 cm. Although the catch was dominated by immature fish (GMS I and GMS II), all GMS stages were present for both sexes, with around a third of females in GMS III-V. Keywords: Scombridae, gonad maturity stage, length-weight relationship, early maturation, fishing pressure.
