Abstract Albuneid crabs are specialized and active sand-burrowing organisms. Despite their substantial diversity, their ability to avoid fishing gear leads to “under collection” and a discontinuous record of distribution. The present study documents the first distributional record of Albunea occulta Boyko, 2002 from the Bay of Bengal, eastern Indian Ocean. Albunea thurstoni Henderson, 1893 is also recorded for the first time from the area, i.e., from the Gulf of Mannar, southwestern Bay of Bengal. This study further reports variation in morphological characters, especially in the carapace grooves (CG) from previous records and across specimens from different regions. Morphometric characters were found useful in species discrimination, which is explained as well.

This study highlighted the occurrence of the Indonesian tuna longline fishery targeting albacore (Thunnus alalunga) caught in the Eastern Indian ocean. The data used in this study based on the Research Institute for Tuna Fisheries (RITF) observer program in Benoa. This paper presents the current information on biological aspect (size distribution and length-weight relationship) and fish behavior (swimming layer and feeding periodicity) of albacore. Total albacore samples of  3,152 were taken from scientific observer data from 2010-2013. The study area of albacore was between 0-33°S and 75-131°E. Albacore length  distributed from 70-196 cmFL (median=93 cmFL, mode=100 cmFL, mean=92.12 cmFL) and dominated at size of 95 cmFL. The highest percentage length of albacore was  >90 cm (L50) occured in the area between (30-35°S and 80-95°E) and (10-15°S and 120-125°E). The length weight relationship was determined to be W=0.0045 FL1.8211  (W in kg, FL in cm). The expected season to catch the ALB was from April to July with the peak season in June and July. The swimming layer of albacore based on minilogger data were distributed from at 118 to 341 m depth and mostly catch at depth of 156 m with temperature degree 18°C.  The feeding periodicity of albacore’s are start from 7:45am to 17:59 pm, mostly active at 10 am to 11 am. The majority of ALB caught by Indonesian longliner was mature condition and negative allometric growth. The ALB peak season was in June-July and the best time to catch was 10 am to 11 am at depth of 156 m. Keywords : albacore, feeding periodicity, swimming layer,  CPUE

Hexanchus spp. are shark species that are often caught in the Indian Ocean southern Nusa Tenggara and its status is Near Threatened, but the information is still relatively limited. This study aimed to sex ratio, length-weight relationship and reproductive size of sixgill shark, Hexanchus spp. caught from southern Nusa Tenggara waters. This study had been carried out during 2016 at the Fishing Port of Tanjung Luar, East Lombok, West Nusa Tenggara. Shark data collection was done by measuring the length, weight, maturity and fishing data. Data were analyzed  by formula of sex ratio, length-weight relationship, length at first maturity (Lm) and length at first catch (Lc). The results showed that Hexanchus spp. caught in the southern Nusa Tenggara waters consisted of H. nakamurai (81.82%) and H. griseus (18.18%). The sex ratio of both sharks was dominated by the female. The average of the total length of H. griseus (218.3 ± 96.08 cm). It was longer than H. nakamurai (127.6 ± 30.35 cm). The length-weight relationship of H. griseus was formulated as W = 0.0195 LT 2,6344 (R² = 0,9265) and H. nakamurai with the formula W = 0.002 LT 3,1098 (R² = 0.902). Both species  have the size of Lm was bigger than the size of Lc which indicated  to their population vulnerability.
