Abstract

Swamp eel Monopterus albus (Zuiew, 1793) breeding was not developed due to limitation of technology. Swamp eel hatchery development may start with male and female eel brood stock differentiation with develop practical method base on morphology. Research conducted to identify morphology differentiation between male and female swamp eel applied truss morphometrics. One hundred male and female swamp eel were used and 18 phenotype characters were measured within head, body and tail parts. Results showed there were 10 phenotype characters able to use as a marker to distinguished male and female swamp eel. Five phenotype characters showed male swamp eel were bigger in size than female swamp eel, included anterior nostril, long of upper jaws to posterior nostril, mouth deep, body and total length. Moreover, five phenotype characters also showed that male swamp eel smaller in compared to female, included length of mouth to posterior of operculum, upper jaws length, head length, vent body width and tail length. In practical, ventral -dorsal of head part able to use as a marker of male swamp eel, in specify characters deep mouth width and stronger jaws appearance. However, female swamp eel was distinguished from longer tail length that related to preparation of gonadal development while adult phase. Body part of male and female swamp eel not able to use as sex marker.

Abstract

The objective of this study is to identify the factors influencing the welfare of blue swimming crab fishermen in the eastern coastal region of Lampung Province. The study was conducted in three regencies: East Lampung, Central Lampung, and Tulang Bawang, with a sample of 100 blue swimming crab fishermen. Daily fishermen use boats with a capacity of 1-2 GT, while babangan fishermen use boats with a capacity of more than 2 GT. The average catch for daily fishermen ranges from 1.99 to 3.18 kg per trip during the east season and from 9.08 to 10.33 kg per trip during the west season. Babangan fishermen catch an average of 74 kg per trip during the east season and 222 kg per trip during the west season. The factors influencing the welfare of fishermen during the east season are income level (X1), number of family dependents (X4), housing conditions (D1), ease of access to education (D3), and ease of access to transportation (D4). During the west season, the influencing factors are income level (X1), education level (X3), number of family dependents (X4), age of the head of the family (X5), ease of access to healthcare services (D2), and ease of access to education (D3).

Abstract

Kiluan Bay is one of the marine conservation areas in Tanggamus Regency, Province of Lampung through which dolphins migrate. This research aims to analyze the relationship between the distribution of sea surface temperature and chlorophyll with the appearance of dolphins in Kiluan Bay. This research uses an exploratory survey method. The research results show that the highest appearance of dolphins was in the Transition Season I, around 117 in the temperature range of 29,44-29,88°C with a chlorophyll concentration of 0,120-0,184 mg/m³ and the lowest in the West Season was around 31 in the temperature range of 28,56-29,34°C with a chlorophyll concentration of 0,096-0,134 mg/m³. The appearance of dolphins is more strongly related to sea surface temperature than to chlorophyll concentration because dolphins do not eat phytoplankton directly where there is a time lag where increasing the chlorophyll concentration value does not immediately have an impact on increasing the intensity value of dolphin emergence, but requires some predation time.

Abstract

Blue swimming crab (BSC) is one of Lampung's main export fisheries commodities. The catch of BSC by fishermen in East Lampung waters is becoming more intensive and increasing from year to year, so it is a concern that it will threaten the sustainability of the stock. This research aimed to analyze the biology of several populations of BSC in East Lampung waters during overfishing conditions. Population biology data on BSC analyzed included growth rate, size at first caught, recruitment patterns, sex ratio, fishing mortality, exploitation level, and a potential spawning ratio. The analyzed data originated from BSC caught by crab net fishermen in East Lampung landed at TPI Kuala Penet and TPI Muara Gading Mas for 1 year (August 2019-June 2020), totaling 35,322 samples consisting of 20,586 males and 14,736 females. The research showed that the level of crab utilization had an E value of 0.71 per year. In these overfishing conditions, it was known that the growth of crabs in these waters was following the equation of CWt= 191,6x[1-e-130(t-(-0,073))]. The carapace width of BSC caught for the first time (Lc) was 119 mm (male) and 123 mm (female) with a sex ratio (M: F) that varied every month between 1:1 and 2:1. Recruitment occurred throughout the year. The SPR was slightly under 20% indicating that overfished conditions had caused the potential for the crab to spawn in an unsustainable condition.
