Anaerobic digestion is one of the best ways to re-use animal manure and agricultural residues, through the production of combustible biogas and digestate. However, the use of antibiotics for preventing and treating animal diseases and, consequently, their residual concentrations in manure, could introduce them into anaerobic digesters. If the digestate is applied as a soil fertilizer, antibiotic residues and/or their corresponding antibiotic resistance genes (ARGs) could reach soil ecosystems. This work investigated three common soil emerging contaminants, i.e., sulfamethoxazole (SMX), ciprofloxacin (CIP), enrofloxacin (ENR), their ARGs sul1, sul2, qnrS, qepA, aac-(6′)-Ib-cr and the mobile genetic element intI1, for one year in a full scale anaerobic plant. Six samplings were performed in line with the 45-day hydraulic retention time (HRT) of the anaerobic plant, by collecting input and output samples. The overall results show both antibiotics and ARGs decreased during the anaerobic digestion process. In particular, SMX was degraded by up to 100%, ENR up to 84% and CIP up to 92%, depending on the sampling time. In a similar way, all ARGs declined significantly (up to 80%) in the digestate samples. This work shows how anaerobic digestion can be a promising practice for lowering antibiotic residues and ARGs in soil.

Length Frequency Analysis

Caranx bucculentus is the most abundant secondary consumer and the most important predator of commercially important penaeids in the Gulf of Carpentaria. More than 18 000 individuals of this species were collected from 406 trawls during 13 cruises in the Gulf of Carpentaria from 1986 to 1991. The species was most abundant in coastal waters, with a maximum biomass at a depth of 28.1 m. Catches were higher in prawn-trawling grounds than elsewhere in the gulf, and prawns comprised a greater proportion of the diet than is the case for other predatory fishes. Interannual variations in biomass occurred, but there were no differences between cruises or seasons. The decreased catches at night may have resulted from vertical die1 migration of C. bucculentus. Sexual maturity is reached at 110 mm standard length and about one year of age, which is much younger than in congeners. Back-calculated birth dates of C. bucculentus show year-round recruitment that peaks in the pre-wet season months of spring, and gonadosomatic index values are generally higher in the pre-wet season than in the wet season. Gonadosomatic index values remain relatively high (> 1.0), which indicates continuous spawning by C. bucculentus in the gulf. Other large tropical species of Caranx spawn annually, in summer. C. bucculentus fecundities range from 18 000 eggs for a 120-mm fish to about 650 000 eggs for a 460-mm fish. A possible switch is seen in the sex ratio-males seem to predominate at smaller sizes, whereas females seem to predominate among bigger fish. MULTIFAN length-frequency analysis gave values of L∞ = 538.8 mm (8 years old) and K= 0.305 year -1. A growth rate of 822 mm year-1 at L∞/2 is comparable to the growth rates of other tropical carangids. The diet of C. bucculentus throughout the gulf is dominated by epibenthic crustaceans and teleosts.

Abstract. In coastal gulfs generally, predominance of wind-seas are expected. Waves measured at a location having a water depth of 15 m in the nearshore waters of Gulf of Mannar during one year period (1 May 2015 to 30 April 2016) is used to examine the predominance of wind-seas and swells through spectral characterization. The study shows that even though the location is in a gulf, the annual average value (~ 0.84 m) of the significant wave height at this area is comparable to that along the coastal waters of the Indian subcontinent, but the annual maximum value (~ 1.7 m) recorded is much less than that (3 to 5 m) observed in those regions. Also, large seasonal variations are not observed in the wave height. The waves of the study region are under the control of sea-breeze with the maximum in the late evening hours and the minimum in the early morning hours. 53 % of the surface height variance in the study area is a result of southeast and south swells and the remaining are the east and southeast wind-seas.

Copepods are the most abundant microcrustaceans in the marine waters and are the major food resource for many commercial fish species. In addition, changes in the distribution and population composition of copepods may also serve as an indicator of global climate changes. Therefore, it is important to model the copepod distribution in different ecosystems. Copepod samples were collected from three different ecosystems (seagrass area, cage aquaculture area and coastal waters off shrimp aquaculture farm) along the coastal waters of the Malacca Straits over a one year period. In this study the major statistical analysis consisted of fitting different probability models. This paper highlights the fitting of probability distributions and discusses the adequateness of the fitted models. The usefulness of these fitted models would enable one to make probability statements about the distribution of copepods in three different ecosystems.

Species of the genus Oryzias are models for studies of adaptation to osmotic environments because they demonstrate inter-species adaptability. Oryzias curvinotus, a fresh and brackish water species, is distributed from the coastal waters of southern China to northern Vietnam. The correlation of O. curvinotus’ distribution with physical water conditions in the Tien Yen estuary of northern Vietnam was recorded during monthly collections for one year. For the current study, a total of 2916 individuals of O. curvinotus were caught, of which 942 were selected to be measured and have their developmental stage recorded: 41 larvae, 749 post-larvae and 152 juveniles or adults. A developmental description and an identification to the species level are also provided. Temperature, salinity and turbidity at collection sites ranged from ca. 17 to 34°C, from ca. 0 to 16 psu and from 0 to 524 NTU, respectively. A peak catch per unit effort was found in April and at the stations at which salinity was about 0.6 to 2.5 psu. In stations where salinity was greater than 17 psu or at 0 psu, few specimens were collected. Examination of distribution indicated a tendency of the species to be present along the estuary, with the center part as the main habitat of this species. The function of an estuarine environment for fishes, which inhabit fresh and brackish waters, is discussed.

Base Of Pyramid

Research was carried out in August 2008 at two sites within Marine Protected Areas (MPA) in Kelapa and Harapan Islands of Seribu Islands, Indonesia. The purpose of this research was to compare the mortality rate of coral transplanted on the upper and base of pyramid-shaped concrete fish shelters. Fish shelters were placed on the seabed of Kelapa Island which is characterized by sandy seabed and Harapan Island which is characterized by silt. Both sites are within Marine Protected Areas. The survey recorded mortality rate of transplanted coral and percentage of live coral coverage. The research also sampled fish populations within the MPA sites and pyramid areas so that the two sites can be compared for their fish biodiversity. The data were analyzed by using T-Test Student of SPSS 11.5 computer program to compare between two locations, and upper and base of transplanted position. After one year, the average mortality rate among transplanted coral species in Kelapa Island was 34%. However, the mortality rate of transplanted coral in Harapan Island was slightly higher than in Kelapa Island: 42%. The transplanted coral at the top of the fish shelter had higher survival rate (39%) compared to the base of the fish shelter (24%). Fish populations in Kelapa Island consisted of 1,119 individuals from 35 species. This was much higher than in Harapan Island where the research found only 655 individuals from 27 species. Fish populations found around the fish  shelter area in Kelapa Island consisted of 125 individuals from 25 species. This was lower than the fish population in Harapan Island, where 206 individuals from 23 species were recorded.
