Abstract. Fauziyah, Mustopa AZ, Fatimah, Purwiyanto AIS, Rozirwan, Agustriani F, Putri WAE. 2021. Morphometric variation of the horseshoe crab Tachypleus gigas (Xiphosura: Limulidae) from Banyuasin estuarine South Sumatra, Indonesia. Biodiversitas 22: 5061-5070. Morphological studies are essential for fish resource management, ecology, conservation, and stock assessment. This research was condu...

distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. as a result, the conventional method finds productive intervals crisply. in this investigation, a net index value is proposed, then; diffusivity equa...

A five years old male individual of Spicara flexuosa was captured by trammel nets on February 13, 2021, at 15 m depths from Black Sea region. The total length and weight were measured as 235 mm 144.06 g. This specimen is the largest that has been reported in coastal waters Turkey. Some morphometric aspects sampled picarel also given. otolith determined 0.0563 Otolith width 8044.31 μm 4596.48 μm...

A 363 foot wide x 19 foot deep x 0.25 inch aperture spillway barrier net fabricated of Dynema was installed in Highline Lake in August 1999 to control escapement of juvenile and adult nonnative fish. The net’s placement met the screening requirement in the Procedures for Stocking Nonnative Fish Species in the Upper Colorado River Basin and allowed the stocking of bluegill and largemouth bass in...

To ensure that a liquid tank semi-trailer has good yaw stability and path-following performance on low-adhesion roads under turning conditions, multi-object PID differential braking-control method is proposed, which takes the tractor rate, articulation angle as control parameters. According to principle of equivalence, trammel pendulum (TP) model used simulate sloshing effect in tank, Fluent so...

This paper discusses the first documented record of Rosy goatfish Parupeneus rubescens in Syrian coastal waters. A specimen (200 mm TL) was captured on 21st May 2020, using trammel nets at a depth 120 m. Ras al-Basit region, 60 km north Lattakia (35°50′ N, 35°50′E). Morphological and taxonomic analysis showed that type individual described present work is newly introduced species Indo-Pacific o...
