Fisheries Research Report No. 354: Recreational fishing for Abalone in Western Australia in 2024/2025 - estimates of participation, effort and catch
No full textThe Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters as a hand collection fishery while wading or diving. Three species of abalone are allowed to be caught. Roe’s abalone (Haliotis roei) are generally collected while wading from the shore in accessible nearshore reef complexes along the West and South Coast Bioregions. Greenlip abalone (H. laevigata) and Brownlip abalone (H. conicopora) are collected while wading (including snorkelling and freediving) and diving (using compressed air) predominantly along the South Coast Bioregion.
Recreational fishing for the three abalone species is licensed and highly regulated, especially in the Western Zone (which includes the Perth Metropolitan Roe’s Abalone Fishery) where fishing is only permitted for a one-hour period on four days per year. The northernmost part of the Western Zone (the Mid-West Region from Moore River to the Greenough River Mouth) was also open to recreational fishing for the 2024/25 fishing season for the first time since 2011
A transcription factor gene CaMYB114 associated with black seed coat in chickpea
No full textBackground
Grain colour is an important quality trait affecting the market value and consumer preference. Chickpeas with black-coloured seed coat is known for their beneficial high antioxidant and fibber content, yet the underlying molecular basis remains poorly understood.
Results
Here, we examined the grain colour trait of a panel of 261 diverse desi chickpea (Cicer arietinum) accessions and specially characterized the development of the black seed coat. We showed that the black colouration emerged on embryo tips at 30 days after flowering (DAF) and expanded to whole grain at 35 DAF. Genome-wide association analyses revealed a single major genetic locus CaBlk3-1 on chromosome Ca3 controlling black seed coat. Candidate gene screening within 0.5 Mb upstream and downstream of CaBlk3-1 identified a single MYB-encoding gene CaMYB114 related to anthocyanin biosynthesis. Phylogeny analyses showed that CaMYB114 was clustered with Arabidopsis MYB90, MYB113, MYB114, consistent with their role in anthocyanin production. Subsequent analyses suggested that CaMYB114 was abundantly transcribed in black genotypes but weakly in the brown genotypes at 35 DAF, closely linked with black colour development. Genetic variation analyses of CaMYB114 identified a 12-bp deletion containing a GAGA motif in the 5UTR region of black chickpea genotype. A gene-specific marker targeting this deletion was developed to validate its link with the black seed coat in a larger chickpea germplasm collection.
Conclusions
We identified a single major QTL and the underlying candidate gene CaMYB114 closely associated with the black seed coat trait in chickpea. Our study has greatly improved our understanding of the genetic basis of chickpea black seed and will unlock the potential for breeding new chickpeas with desired grain colour to meet various market requirement
Large scale genome-wide association analysis identified QTLs associated with aluminum tolerance in chickpea
No full textChickpea has become an increasingly popular healthy food worldwide. Aluminum (Al) toxicity is a major hurdle for chickpea cultivation and yield improvement in acidic soils. However, the genetic mechanism of Al-tolerance in chickpea remains poorly understood. Here, we performed a large-scale hydroponics screening and SNP chip array genotyping of 1154 diverse chickpea accessions. Root lengths after 6 days cultivation under hydroponics in control (T0: pH 4.2) and Al treatment (T1: pH4.2, 15/20 μM Al3+) were measured. Root tolerance index (RTI = T1/T0) ranking revealed significant variations in chickpea Al-tolerance, with common Australian chickpea cultivars positioned in the low to medium range. Genome-wide association analyses revealed eight QTLs on chromosomes ca1 (CaAlt1-1), ca3 (CaAlt3-1), ca4 (CaAlt4-1, CaAlt4-2), ca5(CaAlt5-1), ca6 (CaAlt6-1), and ca7 (CaAlt7-1, CaAlt7-2) associated with T1, implying a multigenic genetic basis for Al-tolerance in chickpea. Specifically, CaAlt7-2 was associated with both T1 and RTI, whilst CaAlt4-2 was detected for T1 uniquely in the HatTrick x CudiB22C population. Al- tolerant and sensitive haplotypes for the identified QTLs were also identified. Organic acid transporter genes CaMATE2, CaMATE4, and CaALMT1 were found in proximal genomic regions to CaAlt7-2, CaAlt4-1, and CaAlt6-1, respectively. Further qRT-PCR in parental chickpea lines (HatTrick, Slasher, Gunas, CudiB) confirmed that CaMATE2 and CaMATE4 were strongly induced upon Al treatment. Interestingly, CaMATE2 was preferentially expressed in the upper part of the root, whilst CaMATE4 preferentially in the root tips, implying a potential complementary role in Al resistance. Their direct roles in Al tolerance and the potential alternative candidate genes near the QTLs require further investigation. This first report of QTLs on Al-tolerance in chickpea has substantially advanced our understanding of the genetic basis of Al tolerance in chickpea and will facilitate the rapid breeding of Al-tolerant chickpea cultivars for previously un-accessible acidic soils
Exploring single cell microbial protein as a sustainable fishmeal alternative in yellowtail kingfish (Seriola lalandi) diets: impacts on health and gut microbiome
No full textBackground
With the global expansion of aquaculture and the increasing demand for fish meal, identifying appropriate and sustainable alternative protein sources for aquafeeds has become essential. Single-cell protein (SCP), derived from methanotrophic bacteria, presents a promising alternative by converting methane into protein, potentially addressing both the need for alternative protein sources and reducing industrial greenhouse gas emissions. This study aimed to evaluate the effects of different levels of SCP inclusion (0%, 25%, 50%, and 75% fish meal replacement) on the health, gene expression, and gut microbiome of yellowtail kingfish (YTK, Seriola lalandi) following a 35-day growth trial. Results
The study found that SCP inclusion at the highest level of fishmeal replacement (75%) induced a mild inflammatory response in the hindgut of the fish. However, micromorphological assessments of the hindgut, serum biochemistry, and gene expression analyses revealed no significant detrimental effects from SCP replacement. Notably, there were indications of improved lipid digestibility with SCP. Furthermore, SCP inclusion significantly enhanced microbial richness and altered the composition of the gut microbiome, introducing beneficial bacterial taxa that may contribute to improved gut health and resilience. Conclusions
This study highlights SCP as a viable and sustainable alternative to fish meal in YTK diets. The findings suggest that SCP can be included in YTK diets without adverse health effects at moderate levels and may even offer benefits in terms of lipid digestibility and gut microbiome diversity. These results contribute to the advancement of more sustainable aquaculture practices
Trenching and compost sustain grain yield increases over nine years on deep sands but at a cost
No full textContext. Crops grown on deep sands on the south coast of WA are limited by soil physical and chemical properties including compaction and poor nutrition. Aims. Crops grown on deep sands on the south coast of Western Australia are limited by soil physical and chemical properties including compaction and poor nutrition. Our aim was to determine what effects deep-placed organic amendments have on soil properties and crop production in a deep sand and whether such amendments are profitable. Methods. A long-term field trial was conducted over nine years (2015–2023) to investigate soil amendments including lime (0 and 2 t ha−1 ) and composted chicken litter (0, 10 and 20 t ha−1 ) with and without incorporation in trenches (0.1 m wide, 0.5 m deep spaced at 0.9 m) in an incomplete factorial design on crop yields, soil chemistry, soil physical properties, root growth and economics. Key results. Grain yields were increased by more than 1 t ha−1 yr−1 where compost and lime were incorporated to 0.5 m. Grain yields for the highest yielding treatments were at or near their rainfall limited yield potential. The yields for surface applied compost did not differ to those that were trenched. The yield increases were attributed to higher nutrient (N, P, K, S) supply, higher pH and organic carbon, reduced bulk density and soil strength within the trench lines, along with increased root activity. The time taken for the compost applied treatments to exceed the cumulative profits of the Control treatment ranged within 19–29 years assuming current prices, costs and yield trends. Conclusion. Reduced bulk density and soil strength associated with trenching was found to persist within the trench lines for at least six years resulting in increased root growth at depth. The addition of composted chicken litter, either surface spread or incorporated in trenches increased grain yields more so than trenching alone. Implications. The compost treatments, although having the highest grain yields, were not commercially viable at the rates applied. The trenched treatments had higher cumulative yields than those treatments that were not trenched. In the absence of compost, the trenched treatments were the most profitable with discounted returns AUD282 to AUD931 ha−1 higher than the Control over nine years
