Abstract Reproductive data are vital for fisheries and conservation management. For cephalopods, reproductive usually obtained by analyzing gonads, which only provide on an individual at a given time require whole deceased specimens. We developed novel method extracting hormones from along the growth axis of chitinous structure could thus lifetime histories. tested our two octopus species taking small subsamples (> 2 mg) beak tissue axis. Estradiol progesterone were detected in both sexes...
The present study investigated the stock structure of snapper (Pagrus auratus) in South Australia, and extent to which this is influenced by adult movement. Fish from 9+ age class were sampled six different regions, encompassing >2000 km coastline habitat types. chemistry transverse sections otoliths was using laser ablation inductively coupled plasma-mass spectrometry, providing elemental profiles that related for first nine years fish’s lives. age-related annual averages both 88Sr 138Ba...
Behavioural lateralization is widespread. Yet, a fundamental question remains, how can be evolutionary stable when individuals lateralized in one direction often significantly outnumber the opposite direction? A recently developed game theory model predicts that fitness consequences which occur during intraspecific interactions may driving population-level as an strategy. This that: (i) minority-type exist because they are more likely to adopt unpredictable fighting behaviours competitive...

The histological effects of cyanide, stress and starvation on the gastrointestinal tract Pomacentrus coelestis , a common marine aquarium fish species, were investigated. Neither anaesthetic cyanide nor found to have any detectable mucosal lining intestine. However, resulted in significant reduction intestine length, surface area intestinal mucosa thickness, all occurring within 13 days.
ABSTRACT This study provides a comprehensive molecular phylogenetic analysis of Uroteuthis squid from the Indo-Pacific region. The main aim was to increase sample coverage northern and eastern Australian waters resolve identity distribution species taken by local fisheries. Two mitochondrial regions, cytochrome c oxidase subunit I (COI) 16S ribosomal RNA (16S rRNA), were sequenced 220 new specimens analysed with further 51 sequences GenBank create combined phylogeny for genus. Three nuclear...
Cephalopods are well known for their diverse, quick‐changing camouflage in a wide range of shallow habitats worldwide. However, there is no documentation that cephalopods use diverse repertoire at night. We used remotely operated vehicle equipped with video camera and red light to conduct 16 transects on the communal spawning grounds giant Australian cuttlefish Sepia apama situated temperate rock reef southern Australia. Cuttlefish ceased sexual signaling reproductive behavior dusk then...
This study assessed the protracted effects of two angling treatments (mild and harsh) on post-release mortality, gonadal development somatic condition Australian bass Macquaria novemaculeata in a pond-based experiment. Angled fish were destructively sampled (along with controls) three times: immediately before, 1 or 4 weeks after release into cages. Compared other groups, harshly angled had similar, low immediate short-term mortalities (< =5%), but significant delayed mortality (25%) fed...
Anemonefishes and their host sea anemones form an iconic symbiotic association in reef environments, are highly sought after the marine aquarium trade. This study examines asexual propagation as a method for culturing geographically widespread commonly traded species of anemone, Entacmaea quadricolor. Two experiments were done: first to establish whether size or colour morph influenced survival cutting into halves quarters; second see feeding was needed maximise growth cutting. Survival...
The effects of barotrauma on the short‐term mortality and physical condition Australian bass Macquaria novemaculeata were investigated after being: (1) conventionally angled released during two tournaments in deep impoundments (2) untreated or subjected to venting recompression a manipulative experiment. All fish into 20 m bathy‐cages monitored for 3 days. Of 238 M. tournaments, 43 (18·1%) had clinical signs vented five these later died (11·6% mortality). Catch histories varied significantly...
Summary The presence of sulfidic sediments (potential acid sulfate soils) is an emerging problem in the management inland wetlands. Using data from 81 wetlands Murray‐Darling Basin, a simple protocol was developed to assess whether wetland will contain at levels that could cause ecological damage. Risk factors include or not receives municipal waste irrigation return water, elevated salinity overlying water (>1750 µS/cm) sediment (400 µS/cm 1:5 soil : extract) and high column (>10...
This study assessed the mortality of 157 snapper Pagrus auratus (9–29 cm, total length, L T ) after being conventionally angled and then released into cages (along with 48 controls) for 4 days off south‐eastern Australia. Fatalities were restricted to 12 fish (7·6%) mostly attributed ingestion hooks especially their subsequent removal, which caused substantial blood loss immediate death. Hook was significantly biased towards smaller (<21 cm a lower chance anglers initially detecting these...
Global octopus catch has doubled over the past four decades and is likely to grow in importance as many key fisheries continue decline. Lack of age data a critical limitation assessing resource status octopus. Over ~30 years, studies have investigated various methods octopus, with some better suited certain species than others. However, only small number researchers hands-on knowledge execute these laboratory. Here, we present first step-by-step guide ageing well decision tool, which should...
